Abstract : The main objective of the study is to investigate the Seismic Response of R.C. Structures with Different Steel Bracing Systems Considering Soil-Structure Interaction. Steel bracing is a highly efficient and economical method of resisting horizontal forces in a RC frame structure. Bracing has been used to stabilize laterally the tallest building structures. the seismic performance of the steel X, Chevron, Inverted diagonal and Eccentrically braced frame structures are investigated considering SSI. The seismic response of a structure is greatly influenced by Soil Structure Interaction (SSI). In this study the effect of soil flexibility on the performance of building frame is investigated. The study is carried out by replacing soil by spring of equivalent stiffness (Discrete Support). Symmetric space frames resting on isolated footing of configurations 4X4 bay 12 storey(4X4X12) is considered with fixed base and flexible base. The spring model is developed by using stiffness equation along all 6 DOF using SAP-2000. For SSI study three types of soil are considered i.e. Hard, Medium Hard and Soft Soil. The dynamic analysis is carried out using Response Spectrum, given in IS1893-2002. The influence of soil structure interaction on various structural parameters i.e. natural time period, base shear, roof displacement, max. column reaction are presented. The study reveals that the SSI significantly affects on the response of the structure as well as bracing system.
