Micro-computer analysis of three-dimensional tall buildings

Abstract

A new approximate method of analyzing three-dimensional buildings by micro-computer is presented. It is based on the fact that the deformation pattern at the nodes of a particular floor can be predetermined before loading. These relative displacements are called distribution factors which govern the distribution of displacements. A number of free parameters are to be determined in the global analysis when the loadings are applied. These parameters are called mixing factors. The linear combinations of the distribution factors with mixing factors as weighting factors will give the actual displacements at the nodes. Structural idealizations of coupled shear walls by beams and columns are recommended. Numerical examples are given and the results are encouraging.
