- Abstract
- Results are presented from the experimental test program on precast concrete beam-column connections subjected to inelastic cyclic loads being conducted at the National Institute of Standards and Technology. The report is the second in a series and covers the test results from Phase II of a three phase program. The objective of the test program is to develop an economical moment resistant precast beam-column joint for high seismic zones. Test specimens are 1/3-scale models of a prototype interior concrete beam-column connection. The 1985 UBC design criteria for seismic Zones 2 and 4 were used. Six specimens were tested. The experimental variables include the location of the post-tensioning force and the type of post-tensioning tendons used. Comparisons of the performance among these specimens are made. Comparisons with the monolithic specimens are also presented. These comparisons are made based on the failure mode, energy absorption characteristics, strength and ductility of the connection.
