Resumen:

An extensive experimental program on full-scale, precast reinforced concrete beam-column connections is under development at the National Autonomous University of Mexico, UNAM. This paper discusses the testing results obtained until date. Comparisons among a benchmark monolithic connection and several precast beam-column joints are presented. After testing, the monolithic connection was repaired using carbon fiber reinforced polymer and re-tested. Precast connections were fabricated using different detailing and various levels of confinement and posttensioning. Preliminary test results reported are compared in terms of strength and deformation capacities. Conclusions, significant to the precast construction industry, have been formulated. The results show acceptable behavior of the precast system. Copyright © 2018 Earthquake Engineering Research Institute. All rights reserved.
