Seismic performance of precast slab to beam connection: an overview

Precast construction is common across the world, but in India the level of acceptance is less, although it offers several benefits compared to the cast-in-place construction. Adopting a suitable connection for pre-cast elements is very important in providing the overall robustness to the structure. Among all precast connections, the precast slab to beam connection is considered a vital one as the horizontal load is transferred to the vertical load resisting structural elements by the diaphragm action. This article mainly focuses on the seismic performance of the precast slab to beam connections with an experimental evaluation of the basic concepts of design and detailing of the connections. This overview will pave way to refine work on the slab to beam connections in future research.
