Abstract:

The corrugated steel sheathed cold-formed steel (CFS) shear wall is an innovative lateral force-resistant system with excellent potential for development. Many research has been conducted on the seismic behavior of this innovative shear wall system. However, dynamic properties as well as the failure mechanism of the CFS structures with corrugated steel sheathing are still unclear. This study aimed to increase knowledge of the seismic performance of CFS structures through the shaking table test, of which the seismic force resisting system was provided by corrugated steel sheathed shear walls. Importantly, this test also took into account the extremely rare precautionary intensity. The main results indicated that damage of CFS structure began to occur in the walls and floors under rare earthquakes and increased further with the seismic intensity. The final damage primarily occurred through the failure of connections and inner panels under extremely rare precautionary intensity. The degree of variation in the dynamic properties of the structure increased further as the damage accumulated. In particular, the damping ratio of the structure in the non-linear phase ranged from 5% to 7.5%. It was unreasonable to assume that the trend of the acceleration amplification factor with structural height was determined as a linear relationship. The peak inter-story drift ratio of the corrugated steel sheathing CFS structure could meet the multi-level seismic precaution requirements of the code. Finally, the seismic performance parameters of the CFS structure were evaluated by numerical simulations. This research will provide a reference for the seismic design of CFS structures under extremely rare conditions. © 2022 Elsevier Ltd
