Abstract
An experimental study of the behavior of precast concrete beam-column connections subjected to cyclic inelastic loading was initiated at the National Institute of Standards and Technology. 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. Results of the experimental tests of both monolithic and precast beam-column connections are described. The monolithic concrete specimens were designed to 1985 UBC Seismic Zone 2 and 4 criteria. The design of the precast concrete specimens was similar to that for the monolithic specimen designed to UBC seismic zone 4. The results from the monolithic specimens provide a benchmark for comparison with the results from the precast tests. The experimental program is divided into three phases. This report presents the findings of the first phase of the test program. Comparisons of the performance of the monolithic beam-column joints with that of the precast joints in which the beam-to-column connection is provided by post-tensioning bars are presented. The effects of fiber reinforced grout between the beam and column are described. Comparisons are made between the energy dissipation, ductility, and failure mode for the two types of beam-column joints.Citation
