Abstract

In this paper, seismic behavior of corrugated steel shear walls arranged in different configurations is studied using fragility curves. Due to the advantages of steel shear walls, the use of this system has been of interest to the executives and designers and its use as a lateral resisting system in practical projects is rapidly expanding. Therefore, consideration of the unknown aspects of this system is important. In the present study, the effect of configuration of corrugated steel shear wall with cold rolled steel in structures with 3, 5 and 7 stories have been investigated. The number of bays in the direction of the shear wall is five, in the first type arrangement, the walls were in the first and the end of the bays, in the second type arrangement of the walls in the middle bays and in the third type arrangement, in the two spans of the first and the end they are staggered. For modelling the behavior of corrugated steel shear walls, previous experimental results have been used. Using static nonlinear analysis and increasing dynamic analysis, Fragility curves, which play an important role in assessing the seismic damage of buildings, are presented for these frames. The results of this study show that in type 2 layouts, the median intensity is higher than the two other arrangements in the structures with different stories. In addition, the corrugated shear walls in low-rise structures are more effective in decreasing the probability of failure subjected to far field earthquakes
