STUDY ON JOINT OF PRECAST SLAB-GIRDER APPLIED IN UNBONDED PRESTRESSED CONCRETE SYSTEM
In reinforce concrete building has a long span and an outer structural frame designed for resisting seismic force, the seismic force of inner structural frame on the building should be transmitted to outer structural frame through a slab diaphragm. In unbonded prestressed concrete systems, the movement of open and shut is a precondition for cyclic seismic load. To solve these problems, mechanical joint of precast slab-girder which transmits in-plane shear force from precast slab to precast girder is necessary. The joint could satisfy required performance was suggested in this research. The structural performance of the joint was investigated experimentally with full scale of slab-girder specimen. In test result, it was confirmed that the shear cotter type of full precast slab accomplished required performance was possessed almost same shear strength with typical reinforced concrete slab.
