Seismic performance of a ductile rod exterior connection system for precast concrete industrial...

[摘要] Precast or prefabricated concrete offers great benefits,such as high construction quality, speed, and economic efficiency.1,2 Considerable efforts have beenmade in recent decades to develop various types of precastconcrete connection systems. Some early studies attemptedto adopt welded connections for joining precast concretebeams and columns. Pillai and Kirk3 used steel plates andbars, welded at the top and bottom ends of the beam, andtested nine full-scale precast concrete beam-to-columnspecimens along with two reinforced concrete specimens.Bhatt and Kirk4 improved the detail of the previous welded connection, which showed premature joint failure, byadding T-shaped steel plates.
