Abstract: This paper presents a simplified method to predict the thermal and mechanical behavior of a new cold-formed steel floor system at room and elevated temperatures. A four-point bending test of such a floor assembly was ...

Abstract: Material properties at elevated temperatures are important factors in the fire safety design and numerical analysis of cold-formed steel structures. Most of the previous research on material properties at high temperatures ...

Abstract: The type of joint used is important with respect to the behavior of grid shells. Prototype static experiments and numerical analyses were conducted to study the mechanical behaviors of a new type of joint: bolted joints ...

Abstract: This paper mainly investigated the buckling behavior of corroded four-sided simply supported plates with longitudinal stress gradients. The effect of corrosion surface topography on the buckling behavior of the four-sided ...

Abstract: The thread-anchored blind bolt (TBB) is anchored by a threaded bolt hole instead of a nut. It can only be mounted from one side, providing an alternative method to build the square hollow section column connection (SHSCC). ...

Abstract: Although a few fire experiments have been carried out on load-bearing cold-formed steel (CFS) wall systems, the understanding of their fire performance is still limited, and further parametric analysis on the basis of such ...

Abstract: The postfire mechanical properties of cold-formed steel (CFS) are fundamental parameters for evaluating the residual performance of CFS structures after exposure to fire. In this paper, 230 tests were performed to obtain ...

Abstract: This paper proposes damage index–based limit-state criteria for seismic design of midrise cold-formed steel (CFS) buildings instead of the drift-based ones, and the Park-Ang damage model was used to calculate the damage ...
