ANALYSIS OF STRUCTURE TO LOCATE THE OPTIMUM POSITION OF OUTRIGGER AND BELT TRUSS SYSTEM IN TALL BUILDINGS

Abstract

Tall Building has always been a vision of dreams and technical advancement leading to the progress of the world. Presently, with the rapidly increasing urbanization, tall building has become a more convenient option for office and residential housing. Thus the burgeoning growth of tall buildings around the world requires novel design methodologies to resolve design challenges. The different lateral load resisting systems are used in high-rise building as there is effect of wind and earthquake forces. Structural system development has evolved continuously to overcome the problems related to lateral stability and sway. Thus to increase stiffness of building against lateral load and to minimize the risk of structural and non-structural damage structural system such as outrigger and belt truss structural system is used. In this study, the position of outriggers and belt truss varies from first storey to top storey in
high rise RC buildings of particular storey height. This paper presents the various techniques and methods used to investigate the optimum location of outrigger system and belt truss in a tall building. The analysis of the structure is carried out and various parameters like storey drift, top storey displacement and natural time period are studied.
