NONLINEAR DYNAMIC ANALYSIS OF THIN STEEL PLATE SHEAR WALLS S. SABOURI-GHOMI and T. M. ROBERTS School of Engineering, University of Wales College of Cardiff, Card8 CF2 IXH, U.K. (Received 21 February 1990) Abstract-A nonlinear analysis of the dynamic response of thin steel plate shear walls, with fixed beam to column connections, based on a finite difference solution of the governing differential equation of motion, is presented. The hysteretic characteristics of steel plate shear walls, incorporated in the analysis, include the influence of shear buckling and plastic yielding of the web plate and plastic yielding of the surrounding frame. The results presented validate the analysis for elastic response and demonstrate the effectiveness of the hysteretic characteristics in inhibiting resonance under periodic dynamic loading. sabourighomi1991.pdf

Interactional Analysis of Steel Plate Shear Wall with Thin Plate using Modified Slope Deflection Method Majid Gholhaki* and Zahra Ebrahimi Sabet** Received May 30, 2014/Revised May 9, 2015/Accepted September 1, 2015/Published Online November 25, 2015 Abstract Steel Plate Shear Walls have been discussed as a lateral load resisting system in various building and especially high-rise buildings. Application of this system in high-rise buildings requires a detailed analysis of the behavior of Steel Plate Shear Walls. This is due to the fact that in high-rise and mid-rise buildings, great axial deformations of columns and aggregation of their effects in height lead to domination of bending displacement. This study aims at analysis of steel plate shear walls using plate frame interaction and modified slope-deflection method (modified slope-deflection method with consideration of axial deformation effect). The plates in this system are equaled by diagonal springs. Plate - frame interaction method is used for calculating plate stiffness. The process of analysis, which aims at reduction of analysis duration, has been conducted in a programming language, thus the analysis of the system and only by changing the values of steel shear wall parameters, is possible with high accuracy and in a very short time. The results of analysis through this method, which uses plate frame interaction method for calculation of plate stiffness, indicate the incorrect assumption of this method in formation of diagonal tension field in post-buckling phase in comparison with the finite element analysis. After modification, the accuracy of this new method has been investigated by changing the parameters of panel width and thickness in this system. Analytical results, compared with finite element analysis, showed good coincidence. The main cause of difference is in the method of calculating the length of the plate which has not buckled and played any role in the post - buckling phase.
