Performance of grouted sleeve connectors in precast wall under four point load test

The need to investigate the use of precast concrete connections is a topic of growing demand. The precast structural members are normally connected via lapping of reinforcement bar. However, the large numbers of connections that are required in precast concrete system pose problems in term of streng...
