Abstract

Purpose

The steel construction market has undergone gradual development in the past decades given its profound impacts on environment, economy and society. The purpose of this paper is to facilitate a better understanding of the major drivers and issues behind the market development of the steel construction industries around the world.

Design/methodology/approach

A three-step desktop research was conducted to select relevant research outputs published in the past 20 years. The research methodology in conducting these studies and their research trends were analyzed. Then the potential influencing factors for the market development of steel construction were identified through a content analysis of the selected studies.

Findings

A total of 59 articles were identified accordingly. These influencing factors were divided into five main themes: contextual, institutional, industrial, project-related and individual factors. In terms of the frequencies of these factors appeared in previous studies, “continuous development of standards, codes, and specifications” and “advance in product and process technology” were the top two driving forces in the market development of steel construction, while “cost issues” was the most frequently reported obstacle.

Originality/value

The study takes an initiative to establish a practical classification framework that can be dedicated to illuminating the critical issues or success factors affecting the development of the steel construction market. This framework can help policymakers, industry practitioners and researchers achieve sustaining success in steel construction in the developed, emerging and inactive markets.

Abstract

Purpose

The purpose of this paper is to select a suitable procurement method for steel building construction in Sri Lanka following a systematic method which weigh, both procurement selection factors and existing procurement systems.

Design/methodology/approach

An abductive research stance is followed in this empirical study. Procurement selection factors were selected through a critical literature review which was followed by a quantitative questionnaire survey. The collected data were analysed using descriptive statistical analysis and relative important index.

Findings

The critical literature review outlined 46 procurement selection factors, out of which 26 factors were very important in steel building procurement selection. Short construction period and higher constructability of design are ranked at the top with the highest priority rating factors. Management-oriented procurement system was selected as the most appropriate procurement system for steel building constructions within the Sri Lankan context.

Research limitations/implications

The study is limited to widely use three procurement systems in Sri Lankan construction industry. Yet, the process followed in selecting the most appropriate procurement system could be applied for other contexts. The implications of the study are mainly identifying management-oriented procurement as the most suitable procurement method for steel building construction in Sri Lanka.

Practical implications

The systematic procedure of procurement method selection for steel building construction may use in the Sri Lankan construction industry to limit the resource loss due to wrong selection of procurement.

Originality/value

A study which critically and comprehensively presenting a procurement selection process for steel building construction is not recorded in Sri Lanka prior to this study.

Abstract

Purpose

The purpose of this study was to select an atmospheric corrosion evaluation methodology and to establish a range of relative corrosion penetration and/or progress values, which could be used as reference in the selection of materials for the civil construction industry.

Design/methodology/approach

Salt spray, field tests, accelerated cyclic tests and accelerated field tests were used to evaluate atmospheric corrosion resistance of civil construction materials. The cyclic accelerated test and the field test with saline solution spray were found to be appropriate for atmospheric corrosion resistance evaluation.

Findings

The corrosion resistance of aluminium killed mild steel, aluminium killed copper added steel, and electrogalvanized steels, all phosphatized and painted, were evaluated by field and accelerated corrosion tests. Of the materials studied, aluminium killed mild steel showed the least resistance to atmospheric corrosion. The use of aluminium killed copper added steel is recommended for material specification in the civil construction industry.

Research limitations/implications

Salt sprays are not adequate to evaluate atmospheric corrosion resistance. There are other cyclic tests that could be tested in future work.

Practical implications

Brazilian technical standards, which specify the metallic materials used in the civil construction industry, will be changed in order to include the construction steel corrosion resistance evaluation methodology, which is proposed in this paper. As a result, the tendency of the construction materials lifetime is set to increase.

Originality/value

This paper contributes to the improvement of the Brazilian Technical Standard by the inclusion of an atmospheric corrosion resistance requirement.

Abstract

Purpose

Government procurement policies containing domestic content requirements have faced increasing attention, as more traditional forms of trade discrimination have declined in recent decades. The most important effort to reduce discriminatory government procurement policies is the plurilateral Agreement on Government Procurement (GPA), in which a subset of WTO countries has agreed to provide increased access to imports from fellow signatory countries. This paper focuses on the Buy American policy, which mandates domestic content for all US Federal government purchase above the micro-purchase level. The author tests whether steel imports from GPA and US Free Trade Agreement (FTA) partners, both of which receive preferential access to US federal procurements, increase as the value of federal construction contracts rise.

Design/methodology/approach

The author tracks federal construction contracts and seeks to determine whether there is a link between these contracts and construction grade steel imports from GPA and US FTA members. The author uses two-stage least squares to regress the import quantity of steel from GPA and US FTA countries on the value of US federal construction contracts. Imported and domestic steel prices as well as macroeconomic variables such as industrial production and non-residential construction are controlled for. A panel data set is used that includes three different construction-grade steel products and covers years 2004-2013.

Findings

The results indicate that increased federal construction contracts increase imports of construction-grade steel from GPA and FTA partners. This effect is relatively small, however, which may be due to the fact that federal construction is a small share of overall US construction. In general, the results suggest that the primary determinant of US import sourcing behavior is the business cycle as well as the price of steel. Nevertheless, the findings indicate that the preferences provided by the GPA and FTAs do have some impact on where US construction firms source their steel.

Originality/value

Previous research has studied the effect of the WTO’s GPA on foreign access to federal construction and other service contracts. This is the first study, however, to investigate whether these contracts impact the import sourcing behavior of the steel that is used in construction. Furthermore, while previous research measures the impact of GPA membership on the overall trade of goods and services, this paper is the first to link a particular industry with the inputs that are restricted by local content requirements such as the Buy American policy but freed up under the GPA. In general, previous research on the GPA has tried to capture the broad effect of GPA membership on trade, while this study focuses on the relationship between the GPA, federal procurement in a particular industry (construction) and import behavior of a key input, construction grade steel.

Abstract

Purpose

This paper aims to investigate the level of awareness about, adoption of and willingness to adopt light steel (LS) for building projects. It also assessed the benefits, challenges and solutions to the challenges of adopting LS for building projects.

Design/methodology/approach

The quantitative (questionnaire) research method was used for the study. The research design was survey in nature. The whole-population cluster sampling technique was adopted. The clusters were the LS buildings from two (Western Cape and Gauteng) out of the eight provinces in South Africa. The respondents were the construction organizations that have executed LS building projects in the selected provinces. Hence, 56 firms filled and returned the questionnaire. Data analysis was done with frequency, mean scores, t-test and analysis of variance (normality of data distribution assumed).

Findings

Results indicated that, out of the 29 areas of application of LS identified in literature, respondents were aware of 11 areas, adopted LS for seven areas and were willing to adopt LS for six areas. Respondents also noted that 18 of the 25 identified benefits of LS were relevant to South Africa. Despite the benefits, few developers embrace it, it is a threat to suppliers’ and contractors’ businesses and it delays building approval due to low awareness.

Practical implication

The implication of the results is that there is low awareness about, adoption of and willingness to adopt LS for building projects in South Africa, and this may be due to the identified challenges. To boost the awareness about, adoption of and willingness to adopt LS, LS technologies need to be imported, LS warehouses should be provided in all cities and it must be ensured that LS building projects are cheaper than conventional buildings.

Originality/value

The value of the study is that the adoption of LS for building projects will improve the capacity of sustainable development.

Abstract

Purpose

The purpose of this study is to investigate the effect of the airgap on thermal behaviour and structural response of fabricated slim floor beams (FSFBs) in fire.

Design/methodology/approach

A detailed analytical model is established and validated by replicating the response of FSFBs. The validated finite element modelling method is then used to perform sensitivity analysis. First, the influence of the airgap presence is analysed, and later, the effect of the airgap size on thermal behaviour and structural response of FSFBs at elevated temperatures is investigated.

Findings

Results from the study demonstrate that the presence of the airgap has a considerable influence on their thermal behaviour and structural response of FSFBs. The size of the airgap, however, has no significant influence on their thermal and structural response in fire.

Originality/value

No investigations, experimental or analytical, are available in literature addressing the effect of airgap on the structural response of FSFBs in fire. The presence of airgap is helpful and beneficial; hence, the findings of this research can be used to develop designs for structural members with airgap as an efficient and inexpensive way to improve their response in fire.

Abstract

Purpose

Concrete-filled hollow section (CFHS) is widely used in steel construction. The combination of concrete and steel decreases buckling and deformation of steel. However, studies reveal that using normal concrete increases the dead weight of a structure. Therefore, a lightweight concrete, such as foamed concrete (FC), is proposed to reduce the weight of the structure. The purpose of this study is to determine the strength of modified fibrous foamed CFHS (FCFHS).

Design/methodology/approach

Steel and polypropylene fibres were used with rice husk ash, and short column fibrous FCFHSs were tested under compression load. Greased and non-greased methods were adopted to determine bond strength and confining effect between steel and concrete.

Findings

Results indicate that the use of fibre in FCFHSs improves the strength of CFHS from 9% to 11%. The non-greased method confirms that an interaction exists between steel and concrete with a confinement coefficient of more than 2.0.

Originality/value

It can be shown that the modified fibrous foamed concrete can increase the strength of the concrete and can be used as concrete filled in steel construction industry.

Abstract

Purpose

This paper aims to investigate computationally and analytically how different levels of restraint from surrounding structure, via catenary action in beams, affect the survival of steel framed structures in fire. This study focuses on examining the mid-span deflection and the tensile axial force of a non-composite heated steel beam at large deflection that is induced by the catenary action during exposure to fires. The study also considers the effect of the axial horizontal restraints, load-ratio, beam temperature gradient and the span/depth ratio. It was found that these factors influence the heated steel beam within steel construction and its catenary action at large deflection. The study suggests that this may help the beam to hang to the surrounding cold structure and delay the run-away deflection when the tensile axial force of the beam has been overcome.

Design/methodology/approach

This paper is part one of the parametric study and discusses both the effect of the axial horizontal restraints and load-ratio on the heated steel-beam. Reliance on the prescriptive standard fire solutions may lead to an unpredicted behaviour of the structure members if the impact of potential real fires is not considered.

Findings

Variation of the horizontal end-restraint level has a major effect on the behaviour of the beam at high deflection, and the loading on a beam at large displacement can be carried effectively by catenary behaviour. An increase of axial horizontal stiffness helps the catenary action to prevent run-away at lower deflections. The studies also investigated the influence of varying the load ratio on the behaviour of the heated beam at large deflection and how it affects the efficacy of the catenary action. The study suggests that care should be taken when selecting the load ratio to be used in the design.

Originality/value

In a recent work, the large deflection behaviours of axially restrained corrugated web steel beam (CWSB) at elevated temperatures were investigated using a finite element method (Wang et al., 2014). Parameters that greatly affected behaviours of CWSB at elevated temperatures were the load ratio, the axial restraint stiffness ratio and the span–depth ratio. Other works included numerical studies on large deflection behaviours of restrained castellated steel beams in a fire where the impact of the catenary action is considered (Wang, 2002). The impact of the induced axial forces in the steel beam during cooling stage of a fire when the beam temperature decreases, if thermal shortening of the beam is restrained, large tensile forces may be induced in the beam (Wang, 2005; Allam et al., 2002). A performance-based approach is developed for assessing the fire resistance of restrained beams. The approach is based on equilibrium and compatibility principles, takes into consideration the influence of many factors, including fire scenario, end restraints, thermal gradient, load level and failure criteria, in evaluating fire resistance (Dwaikat and Kodur, 2011; Allam et al., 1998).

Abstract

Purpose

Steel and reinforced concrete are among the most common structural materials used in the construction industry. Cost and the speed of construction have been usually the main criteria when selecting a building’s structural system, whereby the environmental impact of the structural material is sometimes ignored. Availability of an easy-to-use tool for environmental assessment of the structural alternatives could encourage this evaluation in the decision making. The purpose of this paper is to introduce an automated tool for the environmental assessment of the on-site construction processes of a building structural system, which calculates the energy consumption and carbon emissions of the structural system as a parameter for comparison.

Design/methodology/approach

This assessment tool is implemented using a building information modeling (BIM) platform to extract structural elements and their key attributes, such as type, geometrical and locational data. These data are processed together with a productivity database to calculate machine hours, and then predefined energy and carbon inventories are used to assess the energy consumption of the structural system in the erection/installation stage.

Findings

This assessment tool provides an automated and easy-to-use approach to estimate energy consumption and carbon emissions of different structural systems that are modeled in a BIM platform. The results of this tool were within the ranges reported by the available studies.

Originality/value

This research project presents a novel approach to use BIM-based attributes of the structural elements to calculate the required efforts, i.e. machine hours, and assess their energy consumption and carbon emissions during construction processes.

Abstract

Results of an Investigation to Determine the Effectiveness of a Bi‐metallic Construction on Four Three‐spar Box Specimens Subjected to Simulated Aerodynamic Heating. The maximum thermal stresses in a stainless steel skin‐web combination subjected to aerodynamic heating may be greatly reduced by the addition of a thin layer of aluminium or copper to the stainless steel web. Such bi‐metallic construction increases the rate of conduction of heat from the structural parts (skins) exposed to the aerodynamic heating to the non‐exposed parts (webs) and consequently this produces a reduction in temperature gradients and thermal stresses. This paper presents the results of an investigation to determine the effectiveness of a bi‐metallic construction on a three‐spar box specimen subjected to simulated aerodynamic heating. The tests confirmed the feasibility of the method and indicated that the theoretical calculations give sufficient accuracy for design studies, provided an estimate of the joint conductance can be made. The method is effective only for relatively low heating rates and shallow wing structures. The work reported in this paper was sponsored by the Aerospace Research Laboratories, Wright‐Patterson Air Force Base, Ohio, under project No. 7063, Task 706302.
