Nonlinear Finite Element Analysis of Coupled Shear Wall

Abstract

For medium and high-rise building the use of shear wall is indispensable, since they resist lateral loads very efficiently. Several modeling techniques are suggested for the evaluation of elastic and inelastic behavior of the lateral load resisting structures with shear wall. Finite element method as a numerical tool is used to analyze a six storied reinforced concrete building with shear wall incorporating nonlinear properties. Stringer method of design which divides the structure into elements under tension or compression and shear stresses has been adopted. Static pushover analysis and dynamic time history analysis of the finite element model has been carried out considering material nonlinearity and a combination of material and geometric nonlinearity. Time history analysis has been carried out based on El Centro earthquake data. The results obtained from static and dynamic analysis considering different nonlinearities has been compared.
