Simulation and Behavior of Vertically Oriented Planar Structure

Abstract

AbstractBecause of wind and earthquake, the structural buildings are subjected to laterally horizontal loads, these forces predominate especially in tall and slender buildings. To withstand these lateral loads, vertically oriented planar walls are provided as a lateral resistant component in the building. ABAQUS is the finite element program used for simulation as well as for studying the behavior of a vertically oriented planar wall. The present study aims to explore shear wall response in nonlinear regime under static loading conditions. In the nonlinear analysis of any structure, the formation as well as location of plastic hinge is considered a critical parameter. Hence, the study’s emphasis also includes plastic hinge formation and position through finite element analysis. Nonlinear output of medium aspect ratio shear wall specimens is studied by application of monotonic load on identical shear wall specimens. To further analyze the effect of maximum displacement as boundary condition on the shear wall’s behavior and ductility, a parametric analysis is performed using a concrete damaged plasticity model approach, used to obtain the shear wall’s investigative load–displacement curve and validated with the tested shear wall’s experimentally evaluated curve.KeywordsShear wallPlastic hinge formationPlastic strainConcrete damaged plasticity
