A Technical Review on Reduced Beam Section under Fire loading

In developing India, use of steel for high-rise buildings is increasing day by day. Since we are doing earthquake resistant design but not considering the effect of fire loading in performance of building. Understanding the behavior of steel moment resisting frames with reduced beam section (RBS) under fire loading is critical since many recent events have demonstrated the vulnerability of steel frames to such hazard. In the past few decades, there has been significant progress in structural fire safety analysis and design. However, such analysis relies on simplified methods and experimental data related to structural components, not of the complete systems. There has been very limited attention given on fire safety evaluation at the system level. This paper presents a review of the available experimental and numerical studies on behavior of structural system with RBS connection under fire, current approaches and identifies the research needs and usefulness of RBS connection against connection without RBS for Indian profiles.
