Seismic Performance of Composite Structure Assembled with Cold Form Self-Defending Frame
In recent decades, Cold Form Steel systems are considered as one of the most feasible approaches for constructing residential and commercial low-rise and mid-rise buildings because it has numerous benefits such as environmentally friendly, recyclable materials, light weightness, high performance, cost effectiveness, dimensional modularity, stability and more convenience for construction (Niari, S.E., Rafezy, B., Abedi, K.: Seismic behaviour of steel sheathed cold-form steel shear wall: experimental investigation and numerical modeling. Thin-Walled Struct. 96, 337–347 (2015)). Due to these reasons, Cold Form Steel can be integrated effectively with other materials for instance, concrete to create Composite systems. This study proposes a steel frame assembled with CFS self-defending frame, which acts as a first line of defence thereby preventing the collapse of structures when earthquake strikes. In the present work, an effort was made to study the influence of self- defending CFS structures as an assembled seismic member to improve the seismic performance of steel frame structures (Cao, W.-L., Wang, R.-W., Yin, F., Dong, H.-Y.: Seismic performance of a steel frame assembled with a CFST-bordered composite wall structure. Eng. Struct. 219, 110853 (2019)). The pushover analysis is carried on a bare frame with and without a self-defending frame using ANSYS Workbench R22. Lateral loading is carried on a model with CFS alone and its performance is studied by conducting various parametric changes in optimising the performance by number of horizontal members in self-defending frames and alignment. The analytical results indicate that the seismic performance of bare frame structure was greatly enhanced by introducing assembled Cold Form Steel self-defending frame in structures.
