Most previous thermal-mechanical modeling of cold-formed steel (CFS) walls did not consider the failure of screwed connections under fire conditions because of the limited data of such connections at elevated temperatures.
In this study, 285 steady-state tests are conducted on CFS screwed connections with single-layer gypsum plasterboard (GPB) and Bolivian magnesium board (BMB) sheathing at ambient and elevated temperatures. The failure of these connections is described as the breaking of the loaded sheathing edge.
For the BMB sheathing screwed connections, hydrochloric acid gas is generated and released above 300°C, and the shear strength becomes much less than that of the GPB sheathing screwed connection above 370°C. Hence, BMB may not be suitable for use as the face-layer sheathing of CFS walls but is still recommended to replace GPB as the base-layer sheathing. The major influencing parameters on the shear strength of screwed connections are identified as the type of sheathing material and the loaded sheathing edge distance.
Based on the previous and present test results, a unified expression for the residual shear strength of screwed connections with GPB and BMB is proposed at ambient and elevated temperatures with acceptable accuracy. It can be used as the basic input parameter of the numerical simulation of the CFS structures under fire conditions.

OpenSees is an open-source object-oriented software framework developed at UC Berekeley. The OpenSees framework has been recently extended to deal with structural behaviour under fire conditions. This paper summaries the key work done for this extension and focuses on the validation and application of the developed OpenSees to study the behaviour of composite steel-concrete beams under fire conditions. The performance of the developed OpenSees are verified by four mechanical tests and two fire tests on simply supported composite beams. A parametric study is carried out using OpenSees to study the influence of boundary condition as well as composite effect of slab on the behavior of composite beams exposed to fire. The stress and strain along the beam section is output and compared with yield stress limit at elevated temperature to explain these influences in detail. The results show that the stress distribution in the web of the steel beam is more complex due to the support effects.

The purpose of this study was to examine the characteristics of mainland Chinese hotel firm internationalisation relative to traditional Western internationalisation theory through an analysis of the Shanghai Jin Jiang International Hotels Group’s joint venture with the Thayer Lodging Group to acquire Interstate Hotels & Resorts.
The case study method was used to examine the three firms involved in the joint venture acquisition. The technique of elite interviews was used to collect primary data. Semi-structured personal interviews were conducted with senior corporate executives who were engaged as principals with the conception, execution and administration of the joint venture. Content analysis was performed with the interview data, seeking themes and patterns consistent with the study purpose.
The findings demonstrated specific characteristics that distinguish the internationalisation that Jin Jiang has pursued. The five distinctive characteristics were as follows: a “leap” market entry mode, a pattern of “a small fish eats a big fish”, a preference for purchasing hotels in the West, capital sourcing from Chinese banks and strategic rather than operational control of the acquired firm.
The findings indicate both similarities and differences between the China context of hotel firm internationalisation and that of Western firms. Theoretical implications are examined through an analysis of Dunning’s OLI (ownership, location, internalisation) framework. Generalisability of empirical findings may be limited by the China context and the unique combination of three firms.
The findings advance our understanding of the relationship between Chinese and Western practices, particularly in the approaches that firms take in internationalisation.
The story reported in this paper is about the first firm internationalisation endeavour in the mainland Chinese hotel industry. This is a landmark event for the international hospitality industry that will have historical significance, and represents the leading edge of mainland Chinese hotel firm cross-border expansion. This study contributes an early analysis of how the Chinese hotel sector may approach internationalisation.

The uncertainty of the interval variable is represented by interval factor, and the interval variable is described as its mean value multiplied by its interval factor. Based on interval arithmetic rules, an analytical method of interval finite element for uncertain structures but not probabilistic structure or fuzzy structure is presented by combining the interval analysis with finite element method. The static analysis of truss with interval parameters under interval load is studied and the expressions of structural interval displacement response and stress response are deduced. The influences of uncertainty of one of structural parameters or load on the displacement and stress of the structure are examined through examples and some significant conclusions are obtained.
In this paper we report the progress of our work so far on extending of the OpenSees framework so that it can be used to model structures subjected to fire. The work has focussed on understanding the C++ based object oriented structure of the OpenSees framework, so that all developments remain consistent with it. New classes have been added to introduce temperature dependent material properties for steel and concrete materials. New element classes have also been added to analyse 2D truss and frame structures subjected to fire. This paper will provide an overview of the developments already implemented and present results from using the implemented code to solve a number of benchmark problems and from modelling real fire tests.

Purpose – This study explores the probability of expropriation of minority shareholders by controlling shareholders in the form of CEO compensation under an imperfect governance institution by using a novel Chinese dataset over 2001–2010.
Design/methodology/approach – We use a direct method to gauge controlling shareholders’ tunneling and expropriation of minority shareholders, and we present a simple model to link corporate governance and the degree of entrenchment by the largest shareholder. We use both Logit and Probit models to predict the likelihood of tunneling and use two-stage least square (2SLS) regression to address the endogeneity issues.
Findings – There are significant deterioration effects between controlling shareholder's tunneling and firm performance. Firms with more tunneling activities typically have larger controlling ownership, greater evidence of state control, less balance of power among large shareholders, and weaker board characteristics.
Research limitations/implications – The positive relationship between controlling shareholders’ tunneling and executive compensation implies that the controlling shareholder might divert personal benefits from the public firms at the expense of minority shareholders.
Originality/value – We focus on the effects of corporate governance restructuring on executive compensation and controlling shareholders’ tunneling in the Chinese context, and we also investigate whether these effects are stronger with the involvement of state ownership. We empirically address the issues between executive compensation and expropriation of minority shareholders.
On the basis of analyzing the drawbacks of the existing concurrent engineering (CE), a new concept of agile concurrent engineering (ACE) characterized by the agile teams is presented. The organization method of the agile teams is discussed. The implementation and quantitative process modeling problems of ACE are dealt with. Contrasted with the existent CE, ACE puts the problems of resource sharing into special consideration. Its realization requires as little reform of the current organizational structures of enterprises as possible. ACE is more applicable to the product development in firms, especially in medium‐sized or small companies.

With many years’ economic transformation from “Made in China” to “Created in China,” the State Council has set May 10th as annual “China’s Brand Day” from 2017. This action indicates the implementation of brand strategy and the new national policy of promoting China’s brands. The purpose of this paper is to examine the influence of marketing background of top management team (TMT) on trademark and brand output.
Using the trademark application data of Chinese-listed companies, this paper constructs a multiple linear regression model and uses the OLS method. This research also uses two-stage regression to examine the effect of endogeneity on the results.
Our results show that the higher the proportion of executives with marketing background in TMT, the more the number of trademark applications. Furthermore, we document that the positive impact of TMT marketing background on the number of trademark applications is more pronounced in non-state-owned enterprises, companies with more patent output and companies whose CEO has marketing background, indicating that when TMT can play a bigger role, companies have better innovation ability and team collaboration is more efficient, the promoting role of TMT marketing background on the number of corporate trademark applications will be stronger.
This research focuses on the world’s largest emerging economy – China, which is different from the existing literature that is mainly based on western developed countries. With China’s economy stepping into a new normal and consumption upgrading, it is important and worthy of a deep discussion about which factors affect the company’s trademark and brand management.

The widespread family businesses play an important role in the national economy of developed countries in Europe and North America, or of developing countries in East Asia. However, family business succession is a worldwide difficult problem. The innovative family business succession practices of Robert Bosch GmbH, the German family company which has a history of 130 years (1886-2016), basically follow the trend of evolving from family businesses to social enterprises after further socialization. However, it has its own innovation and uniqueness which is worthy of reference by Chinese family businesses.

Although an important facet of modernist architecture in which function plays a prominent role, building flexibility is not entirely a new concept. Its relevance transcends generations, allowing space and structure to evolve through time. This paper investigates the relationship among main building structures, infill elements, and space by studying examples in ancient Chinese architecture. It reveals the role of building owners, users, and craftsmen from a survey of historical documentation. In studying these examples, it is concluded that craftsmen in ancient China were involved not only during the construction phase but throughout the period of use as well. Thus, in select cases, the relationship between craftsmen and owners or users had been preserved for generations. Finally, this paper suggests potential strategies for the building industry and technology in the move towards sustainable development.
