Stability of tall buildings with shear-wall structures

摘要

An analytical model of a flexural-shear plate is proposed herein for the purpose of bucking analysis. In this paper, tall buildings with shear-wall structures and with narrow rectangular plane configuration are modeled as flexural-shear plates for buckling analysis. The governing differential equation for buckling of a flexural-shear plate with varying cross-section is established. Using appropriate Transformations, the equation is reduced to an analytically solvable equation by selecting suitable expressions, such as power func- Tions and exponential functions, for the distribution of stiffness along the height of the plate. The exact solutions for buckling of A flexural-shear plate with variable stiffness are derived. A numerical example that the present methods are easy to implement And are efficient.
