APPROXIMATE ANALYTICAL MODEL FOR MULTISTORY FRAMES.

Abstract

A method of analytically modeling multistory building frames to reduce the scale of the problem of finding the effects of varying girder, column or bracing stiffnesses is presented. Three example calculations, conducted on an IBM 1130 using STRESS, are given and the authors conclude that three-dimensional structures, such as tube and tube-in-tube type structures composed of closely spaced columns around the perimeter interconnected with stiff spandrels, can be analyzed on a small computer with the use of the modeling techniques presented.
