INVESTIGATION OF CONCRETE FILLED COMPOSITE PLATE SHEAR WALLS USING FINITE ELEMENT METHODS

Abstract

Concrete filled composite plate shear wall is an innovative structural lateral force resisting system that is being investigated experimentally and numerically. It consists of pre-fabricated steel web plates that are spaced parallel to each other by having regularly spaced cross-connecting tie bars (rods) which is then filled with concrete. This paper make use of previously developed numerical models and extends the study to investigate different aspects of wall behavior. In this study, two of the previously tested wall models were used to investiagete percentage of steel plate yielding at certain wall elevations per certain drift levels, steel plate von-Mises stress contours, the distribution of cracks in concrete, relative contribution of steel plates and concrete to total wall base shear and axial stress distribution of steel plate and concrete. The study assumes fixed-based walls and describes the development of finite element models using LS-Dyna.
