SEISMIC PERFORMANCE OF PRECAST CONCRETE BEAM-COLUMN JOINTS

Abstract

An experimental study on seismic behavior of precast concrete beam-column joints is presented in this paper. The objective of this study is to investigate the beam-column joint seismic behavior of a newly developed precast concrete system which can make the connections more economical and easily constructed. Nine two thirds scale beam column joint specimens were tested under simulated seismic action. Test results indicated that the propsoed method of connection presents an adequate strength, stiffness and ductility when subjected to large inelastic deformations under cyclic loads.
