Seismic response analysis of corrugated steel wall under Earth load - Seismic Fault area far and near

Erfan Pourmohammadi

Abstract This study examines the seismic response of corrugated steel shear walls under land load-seismic seismic distant and near fault zone. Corrugated steel shear walls are used as an efficient lateral resistance system in earthquake-resistant structures due to their formability and high energy dissipation capacity. The use of corrugated steel sheets has several benefits, including increased shear strength, improved bow behavior, and reduced structural weight. However, earthquakes in the nearby fault zone, due to the presence of high-speed pulses and permanent displacement, can cause more damage to these walls. In this study, using Abacus software, a three-dimensional model of a corrugated steel shear wall was created and subjected to accelerated loading of seismic scales in the distant and near fault area, nonlinear dynamic analysis was carried out. The results showed that corrugated steel shear walls exhibit optimal seismic performance against earthquakes in the far and near fault zone. However, the seismic response of these walls under near fault zone earthquakes differs significantly from their response under far fault zone earthquakes. In the design of corrugated steel shear walls for areas near the fault, the effects of velocity pulses and permanent shifting should be considered.
