Improving the performance of precast concrete beam-to-beam connection with inadequate lap length

This paper reports on a feasibility study of different types of precast concrete beam-to-beam connections under inadequate lap length. The aim of the study is to develop a beam-to-beam connection, which is able to produce comparable bond strength with the conventional lapping system although the anc...
