Effect of Floor Diaphragms on Seismic Response of RCC Framed Building—A Review

Abstract

Diaphragms are required to be designed as part of the seismic force-resisting system of every new building as they distribute lateral forces to the vertical elements of lateral force-resisting system. Concrete diaphragms consist of different element which plays an important role in resisting lateral loads. It can be conventionally reinforced or prestressed and can be cast-in-place concrete, topping slabs on metal deck or precast concrete, or interconnected precast concrete. For analysis of building structure, modeling of floor diaphragm plays important role. Diaphragms acts differently according to the configurations of the building and type of load acting on it. So it will require different methodologies to study their behaviors. This paper is an effort made to review the literatures available for modeling of floor diaphragms.
