2013-11-1  1. Introduction. Precast concrete members have various advantages in service and quality in comparison with cast-in-place concrete ones: better allowance for quality control, ready supply of good quality aggregates, and much higher strength due to better batching and quality control of concrete through the use of a specialized labor force under factory conditions.

Development and testing of hybrid precast concrete beam

In general, precast concrete structure has insufficient ductility to resist seismic load. Detailed understanding on the behaviour of precast concrete connections are limited and current researches are focused addressing this. In this study, two precast and two monolithic concrete joints for exterior beam-to-column connection were tested under cyclic loading.

2017-10-1  Past study on a dry precast concrete joint used two steel plates embedded at the top and bottom of the main concrete beam to test the joint under cyclic loading. The two steel plates were connected to column brackets by welding. The design of this connection was subsequently improved by the addition of plates at the sides of the beam.
