An efficient analysis of continuum shear wall models

Abstract

This paper formulates the stiffness matrix and a procedure for the analysis of a general class of coupled shear walls subjected to arbitrary loading and boundary conditions. The computed solutions for both deflections and stresses are exact in the sense that they satisfy the governing differential equation of the continuum shear theory, as well as all boundary conditions and inter-element compatibility. Explicit expressions are given for the formulation of the stiffness matrix and of the fixed-end forces for common loading conditions. The theory is also applicable to shear walls having variable stiffnesses and multiple bands of opening.Key words: coupled shear walls, stiffness matrix, finite element, structural analysis, structural design.
