Abstract

Steel plate shear walls (SPSWs) as a resistant system against lateral loads have a high potential for earthquake energy dissipation. Due to the uncertainties of loading, construction, and installation of SPSWs, it is vital to investigate the importance of each component and achieve higher accuracy in design and the implementation of these members. In this paper, a sensitivity analysis is carried out to determine the significance of important uncertainties. The results denoted that the most important parameters affecting the loading capacity of the SPSWs are height, thickness, length, Young’s modulus of the wall material, flange, and web thickness of the column, respectively.

Highlights

This research focused on unstiffened SPSW and was subjected to monotonic loading
The authors attempted to investigate the significance of various parameters of SPSW in terms of affecting the capacity curve

Summary

Introduction

Steel plate shear walls (SPSWs) has been attracted by engineers' attention as lateral force-resisting systems in structures. A STUDY ON THE SIGNIFICANCE OF THE DESIGN PARAMETERS OF STEEL PLATE 143 SHEAR WALLS SUBJECTED TO MONOTONIC LOADING and wind, especially in tall buildings. It can be utilized along with concrete frames to improve the system's lateral rigidity [1, 2]. The objective of this study is to identify the important uncertain parameters and indicating important variables that should be considered for design To this end, the Monte Carlo simulation as a computational approach of analysis is used, which deploys statistical sampling techniques to obtain a probabilistic approximation to the solution of a model. The parameters of the steel wall are defined, and the sensitivity analysis is conducted
