|Title:||Performance of 1/3-Scale Model Precast Concrete Beam-Column Connections Subjected to Cyclic Inelastic Loads. Report No. 2|
|Published:||June 01, 1991|
|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. This 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 mode, energy absorption characteristics, strength and ductility of the connection.|
