Parametric Study on Multi-Storey RC Building with Belt Truss System

Abstract

Due to the advances in structural systems nowadays building became light weight, and slenderness is increased. Which is the reason why the lateral loads are required to be considered. These lateral loads are wind and earthquake load. For resistance of this lateral loads in tall buildings, identification of proper structural system is must. For lateral resistance of tall buildings, there are many structural systems. In tall buildings, the stiffness of the building becomes more important. Thus, the belt truss outrigger system is used in tall building to provide sufficient lateral stiffness. Outrigger and belt truss system is one of the structural system which controls the excessive drift due to lateral load. The risk of structural and non-structural damage can be lowered during wind or earthquake load by using this system. Outriggers in the building results in less usable space on particular floors. In this research work the behaviour of building having 2 belt trusses with outrigger system and building having 3 belt trusses with outer shear wall are studied for 30, 40 and 50 storey RC buildings.
