Performance Estimation of Solid and Punched Shear Wall Buildings with Two Modelling Techniques

Abstract

Shear walls are generally provided in multistoried buildings to resist in-plane lateral loads by increasing strength and stiffness to control the lateral deformations. Various modelling techniques are available to model shear wall in computer models, viz. nonlinear layered shell elements, wide column, fibre elements or truss elements. The accuracy of results and time required for the analysis depends on the modelling technique adopted. In the present paper, parametric study of two modelling techniques of shear wall, i.e. wide column approach and nonlinear layered shell element, has been discussed for solid and punched shear walls. Response spectrum analysis and nonlinear static pushover analysis have been performed. In linear range, the modal analysis results, shear force and moment in the shear wall from aforementioned approaches are comparable. From nonlinear analysis, it has been observed that the wide column approach is unable to capture progressive nonlinearity in the shear wall and overestimates the stiffness of the structure.
