Abstract:
An experimental study of precast concrete beam-column connection assemblies is presented. The study was initiated to provide data for the development of a rational design procedure for such connections in high-seismic regions. The objective of the study is to develop a moment-resistant precast concrete connection that is economical and easily constructed. All test specimens were 1/3-scale models of the prototype. The monolithic concrete specimens were designed to 1985 Uniform Building Code (UBC) seismic zone 2 and 4 criteria. The designs of the precast specimens were similar to those for the monolithic specimens designed to UBC seismic zones 2 and 4. Results from the monolithic specimens provide a benchmark for comparison with results from the precast tests. Comparisons of the performances of the monolithic beam-column connections with those of the precast, post-tensioned connections were based on the connection strength, energy absorbed, ductility, and failure mode for the two types of beam-column connections.
