A Experimental Study on the Shear Resistant Characteristics of the Large Precast Concrete Panel Structures

Precast concrete panel buildings are designed to tracsmit shear forces through the joint between the reinforced concrete panels. The shear strength is partly provided by the resistance to sliding at the interface between the precast and in- situ concrete and partly by the dowel action of the reinforcement crossing the joint. The shear resistance to sliding is largely dependent on the shapes and configurations of vertical joints and the vertical loads of horizontal joints. In this paper, the shear strength by the difference of relative strength between panel and joint, the effect of reinforcement, and the effect of vertical load are considered.
