SEISMIC PERFORMANCE OF ISOLATED NONSTRUCTURAL CONCRETE PARTITIONS WITH DOWEL-BAR CONNECTORS UNDER CYCLIC LATERAL LOAD

摘要

Nine full-scale isolated non-structrual reinforced concrete panels with in-plane dowel connectors jointed to the surrounding structural frames were tested under cyclic displacement-controlled seismic loading to quantify the strength and the ductility of the panels and to assess the damage of the non-structural partitions. The specimens were installed in a steel loading frame of lateral resistance free and were loaded until the fracture of dowel connectors which caused significant reduction of lateral resistance. The test parameters include: (a) panel dimensions, (b) amount and arrangement of the dowel connectors, and (c) gap distance between panel and frame. Test result indicates that the precast concrete panels could provide strength increase of the structural system, desirable deformation capacity and additional energy dissipation capability if appropriate dowel-bar connecting details were provided.
