STIFFENING ANALYSIS OF BUILDINGS ERECTED IN THE IMS SYSTEM

Abstract

The bracing of buildings of the prefabricated and prestressed IMS skeleton system is provided by sway-to-shear and sway-to-bending structural members. An analysis of their contribution to the lateral stiffness is presented in this study. The adopted method is subjected to N.Rosman's theory. An illustrating numerical analysis reveals that a casual deficiency of the framework rigidity of the nodes due to decrease of prestressing effect can cause a remarkable redistribution in the loading conditions of the bracing diaphragms.
