Review on seismic performance evaluation of precast concrete buildings

Abstract

Precast concrete multistoried building systems have become a reliable solution for mass housing projects. Literature on the failure of precast buildings during past earthquakes reports poor connections and improper ductility considerations. This paper emphasizes the role of various ductile framed connections (emulate monolithic and hybrid connections), shear wall systems and diaphragm slab panel connections in lateral load transfer. The sequential development of these systems, codes and standards recommendations and construction practices in various parts of the world are discussed in detail. Experimental and analytical studies are also pointed out in developing these precast ductile systems. The importance of ties, the requirement for splicing and anchoring inserts, and their code requirements are also highlighted. The advancement of experimental studies and numerical computing technics helped in the understanding of linear and nonlinear behaviour of precast systems. Developing and implementing local building codes and procedures to ensure safety against catastrophic failures is an ultimate disaster mitigation measure.
