Performance Based Seismic Design of Braced Composite Multi Storied Building

摘要

Steel-concrete composite construction system is an efficient, economical and innovative method for seismic resistance of multi storied buildings. This paper represents a study on economic aspects of G+4 multi storied building designed by using braced frame composite construction. Since ductility, stiffness, inter storied drift and lateral displacements are the critical issues in seismic design of buildings, different types of braced frame models are developed in this study and evaluated its structural performance. Equivalent static method of seismic analysis used in the analysis of geometric models and the results are compared with STRAP software. This study makes an attempt, to develop efficient geometric models for new constructions, and to provide necessary structural configuration against retrofitting of the existing structures, constructed in earthquake prone regions.
