The way that disasters are managed, or indeed mis-managed, is often represented diagrammatically as a “disaster cycle”. The cyclical aspects of the disaster (risk) management concept, comprised of numerous operational phases, have, in recent years, been criticised for conceptualising and representing disasters in an overly simplistic way that typically starts with a disaster “event” – and subsequently leads onto yet another disaster. Such cyclical thinking has been proven to not be very useful for the complexities associated with understanding disasters and their risks. This paper aims to present an alternative conceptualisation of the Disaster Risk Management phases, in a way that can better factor in the underlying root causes that create differential levels of vulnerability.

This is a conceptual paper developed, through a review of the literature and discussions between the authors, as a counterpoint to the pervasive “disaster cycle”.

The “Disaster Risk Management (DRM) Helix” is presented as an alternative way of conceptualising the DRM phases. The helictical conceptualisation of DRM phases presented in this paper is intentionally presented to start a discussion (rather than as an end point) on how best to move away from the constraints of the “disaster cycle”.

It is envisaged that the helictical conceptualisation of DRM can be suitably malleable to include important factors such as temporal considerations and the underlying root causes that create differential levels of vulnerability. It is, thus, the intention that the DRM Helix can provide a catalyst for exciting discussions and future adaptations of the diagram that can better capture the dynamic (non-cyclical) nature of disasters and their root causes.

Flood resilience is emerging as a major component of an integrated strategic approach to flood risk management. This approach recognizes that some flooding is inevitable and aligns with the concept of “living with water.” Resilience measurement is a key in making business case for investments in resilient retrofits/adaptations, and could potentially be used to inform the design of new developments in flood prone areas. The literature is, however, sparse on frameworks for measuring flood resilience. The purpose of this paper is to describe the development of a fuzzy logic (FL)-based resilience measuring model, drawing on a synthesis of extant flood resilience and FL literature.

An abstraction of the flood resilience system followed by identification and characterization of systems’ variables and parameters were carried out. The resulting model was transformed into a fuzzy inference system (FIS) using three input factors: inherent resilience, supportive facilities (SF) and resident capacity.

The resulting FIS generates resilience index for households with a wide range of techno-economic and socio-environmental features.

It is concluded that the FL-based model provides a veritable tool for the measurement of flood resilience at the level of the individual property, and with the potential to be further developed for larger scale applications, i.e. at the community or regional levels.

This study aims to investigate the level of preparedness among property owners who had experienced flood damage to their properties in two cities in England following the summer floods of 2007. Flooding can have a variety of impacts on residential properties and businesses that may be unprepared and therefore vulnerable to both direct and indirect effects. Research suggests that the focus in analysis of damage to flood plain population (residential and commercial) tends to be on the direct tangible impacts, limiting their ability to recognize the true costs of flooding, thereby leading to unpreparedness to future flooding. Greater understanding of the level of preparedness against different types of flood impacts is likely to contribute towards increased knowledge of the likely resilience of residential and commercial property occupiers.

Primary data obtained through self-administered postal questionnaire survey of floodplain residential and commercial residents provide the basis for the research analysis and findings. The rationale behind choosing the locations for the research was based on the need to investigate areas where a sizeable number of residential and commercial properties were affected during the 2007 event, in this case, Sheffield and Wakefield in the northern part of England were chosen. The data collected were subjected to descriptive statistical analysis.

The result of the analysis revealed that non-structural measures have been implemented by more people when compared to other measures, which can be linked to the fact that non-structural measures, in most, cases do not have financial implication to the property owners. The uptake of the other measures (resistance and resilience) is very low. It can be concluded from the findings that the level of implementation of measures to reduce damage from potential future flooding among the flood plain residents is relatively low and mainly focussed towards reducing the direct effects of flooding.

The study argues that increased resilience can be sustainable only by developing integrated attitude towards risk reduction not only by enhancing coping strategy by reducing direct impacts of flooding but also equally focussing on indirect effects.

There have been previous studies towards investigating the impacts of flooding on residential and commercial property owners as a separate entity. It is believed that this is the first time in which both residential and commercial properties will be investigated together as one body of research.

Understanding the technical and socioeconomic dimensions to resilience is core to making a business case for property-level flood risk adaptation. The study investigates the socioeconomic factors that impact the technical dimensions to property-level flood risk adaptation, and whether there is a typology of households adopting similar adaptation measures in Port Harcourt.

Exploratory and inferential statistical analysis of data collated from 407 questionnaires was carried out. Using chi-square analysis, significant bivariate associations were sought between the level of uptake of different categories of property level adaptation and the socioeconomic characteristics of households. A two-step cluster analysis was used to explore discernible patterns of households implementing similar adaptation measures. Logistic regression analysis was further used to evaluate the extent to which socioeconomic parameters impact residents' willingness to undertake adaptation measures given the option of relocation.

The chi-square analysis highlighted a lack of significant association between some socioeconomic parameters and the uptake of individual adaptation measures. The regression analysis however showed that the socioeconomic parameters exert varying degrees of influence on the residents' willingness to undertake adaptation measures. Two homogeneous groups of residents with similar socioeconomic characteristics were identified via the cluster analysis but did not translate into strongly discernible adaptation differences/patterns.

The study shows that although socioeconomic parameters to some extent underlie the technical dimensions to flood resilience, there is no distinctive typology of households in Port Harcourt adopting a similar combination of measures.

The study offers insights into understanding property-level flood risk adaptation responses within the context of the developing world.

This paper aims to present phenomenological extensions and technical improvements of a recent research path on a potential operational scheme aiming at promoting an effective disasters risk reduction of built urban areas, namely, the proposal of a Certification of the Predisposition of Resistance of Edifices to Disasters.

The authors illustrate new steps of a multidisciplinary research conducted by merging different fields of study, such as disaster risk analysis, sustainable land use and urban planning, environmental assessment methods, different buildings safety topics and certification and auditing management systems tools.

This work is based on research developed in Italy by carrying out new tests in the coastal regions of Liguria and Tuscany to validate improvements and to confirm in different territories the assessment process of most significant natural and man-made hazards already included in the certification scheme previously developed on the basis of the continental regions of Lombardy and Piedmont.

Investigations and results give firmer foundations and exploitability to a certification such as the one presented here.

This paper aims to present technical aspects of the assessment method and evaluation of fire damaged steel structures. The current work focuses on the behavior of structural normal steel (hot-rolled and cold-formed) and high-strength bolts after exposure to elevated temperatures. Information on stainless steel, cast iron and wrought iron is also presented.

Because of the complexity of the issue, an elaborate presentation of the mechanical properties influencing factors is followed. Subsequently, a wide range of experimental studies is extensively reviewed in the literature while simplified equations for determining the post-fire mechanical properties are proposed, following appropriate categorization. Moreover, the reinstatement survey is also comprehensively described.

Useful conclusions are drawn for the safe reuse of the structural elements and connection components. According to the parametric investigation of the aforementioned data, it can be safely concluded that the most common scenario of buildings after fire events, i.e. apart from excessively distorted structures, implies considerable remaining capacity of the structure, highlighting that subsequent demolition should not be the case, especially regarding critical infrastructure and buildings.

The stability of the structure as a whole is addressed, with aim to establish specific guidelines and code provisions for the correct appraisal and rehabilitation of fire damaged structures.

The existing housing stock needs substantial adaptation to meet national and international carbon reduction targets. The largest proportion of housing is owner‐occupied, and will require improvement works which go beyond those measures provided through the Green Deal and similar programmes. Therefore, the motivation of owner‐occupiers to perform more substantial energy efficiency refurbishments is essential to facilitate greater action. This paper aims to address these issues.

A synthesis of the extant literature from a range of disciplines reveals the role of motivation and the factors influencing motivation and pro‐environmental action in the context of the home. Based on this synthesis of the literature, a new motivation model for energy efficiency refurbishment in the owner‐occupied housing stock is then described.

The study has found that multiple factors affect motivation to refurbish in the owner‐occupied housing stock. Key motivations for energy efficient refurbishment can be categorized into the broad themes of economic, social, and environmental motivations. These motivations will be affected by a wide number of interrelated internal and external factors and mediated by the emotions of the individual. The model presented demonstrates the relationship between the multiple factors that affect energy efficiency refurbishment in relation to specific contexts.

The study represents a potential addition to motivational theory and concepts for use within the field of energy efficient refurbishment of the owner‐occupied housing stock. Implications for future government policy and towards raising the motivation of owner‐occupiers are identified: it can be used to shape national and local policy and information campaigns to motivate energy efficiency refurbishment in the owner‐occupied housing stock. To be successful, this should take differing internal factors and contexts into consideration and the dynamic nature of owner‐occupier motivation. The model can also be used by industry professionals to better understand the owner‐occupier customer motivations for energy efficiency refurbishment and therein provide a better service.

The purpose of the research is to develop a conceptual framework to anticipate the vulnerability of value of commercial properties towards changing risk of flooding. The existing patterns, themes, and issues associated with property value and their vulnerability towards flooding were identified and used to inform the development of the conceptual model.

Literature review is performed to identify the factors affecting vulnerability of commercial property values to the impact of flood risk in the UK. The review approach was based on related literature contributing to identified themes and sub-themes. The extant literature is summarized into two distinct themes of “vulnerability” and “value” contributing to changing risk of flooding. The synthesised literature is then utilized in developing the conceptual map which further paved the way towards designing the conceptual framework.

The generic conceptual framework presented explores the interaction between different internal and external influencing factors affecting the vulnerability of value of commercial property system. The framework highlighted the importance of space and time within the system. An extensive review of previous studies in both the residential and commercial sectors for different disaster studies reveals that the main research challenge in assessing the vulnerability of property values are the intensive data requirements. The need for data is considered to be the main restrictive factor resulting in lack of empirical studies in this field.

This study brings together two existing research domains of flood vulnerability and property value. Practitioners and researchers will find this study useful in developing an improved understanding of the vulnerability of commercial properties to flooding. The conceptual framework is an important outcome of the research which will encourage further research in this considerably neglected field.

Climate change will present many new challenges for professionals in the built environment. Observers have speculated that the increase in damage to property caused by more frequent and severe flood events may result in loss of property value. However a consistent link between flood risk and value has not been proven in the UK to date. This paper aims to investigate the impact of flooding on property value in the UK.

As part of an ongoing study into the impact of flooding on property value in the UK, the available international evidence has been examined and general lessons drawn. A case study is presented of an example site, flooded in 2000, using actual transaction data.

This research demonstrates that, in general, there is a tendency for people to forget about the risk of flood damage with time. However, various manifestations of floodplain designation or regulation including mandatory insurance purchase can maintain awareness in the longer term. For the case study the impact of the flood on house prices is seen to be temporary, lasting less than three years.

Both the case study and the previous international research indicate that studies of the price impact of flood events should consider temporal aspects. Tentative conclusions from a single case study suggest that taking the long view of likely future recovery could promote price stability for flooded communities.

The discounting of flood‐prone property is naturally of concern to property stakeholders including the valuation profession and property owners. This research is unique in using transaction data to measure flood impacts in the UK.
