Abstract

Steel bracing is economical, easy to erect, occupies less space and has flexibility to design for meeting the required strength and stiffness. In the present study, pushover analysis of complex steel frame building was investigated. These investigations were based on stiffness and ductility. This paper is intended to compare the performance of structure by  using ISMB  and ISNB(hollow pipes) steel sections as bracing element on 15-story complex steel frame. Displacement analyses were performed using the Extended 3D Analysis of Building Systems (ETABS) software for investigating stiffness of these system and pushover analysis were performed. The results of these outputs indicated that performance of structure greatly influenced by the way and sections adopted for bracing system.
