Study on Lateral Resistance Behaviour of High Rise Building with Shear Wall and Bracings

Abstract

Shear walls and bracing systems are the most appropriate structural forms in the recent decades. A shear wall is a wall that is designed to resist shear i.e. the lateral force that causes bulk damage to the structures during earthquakes. Bracing is also a highly efficient and economical method of resisting horizontal forces in a frame structures. The aim of this work is to study the structural aspects of an R.C building with G+32 stories are to be considered for lateral forces using structural components such as R.C shear wall and bracings. This structural system using a core wall carries the seismic lateral forces which improves the design flexibility of super-high-rise condominium. Non-linear analysis was done in ETABS 9.7.4 to check the lateral force resistant behavior of components. By providing shear wall and bracing the lateral forces are resisted by the structural components which have increased stiffness, deformability and decreased drift. This analytical investigation on R.C shear wall and bracings for lateral load resisting is compared with ordinary R.C structures. The effects of various geometries were analyzed, results were compared and presented in this paper as per IS code methods.
