합성슬래브 효과를 고려한 PR Connections의 내진성능

PR Connections have some rotational stiffness and develop the moment capacity that isn't larger than the full plastic capacity of the beams, PR Composite Connections can secure the adding strength and stiffness by composite of slab and the equal or more performance than bare steel PR connections. The study for the seismic performance of connections(FR, PR Connections) were progressed actively after the Northridge earthquake and FEMA 355D presents the seismic performance of PRCC. In Korea, analysis studies for PRCC has been behaved mostly. So, development of connection details and testing studies which can be used in weak-earthquake regions are incomplete and needed keenly by the seismic performance strengthening of KBC2005. This study considers the performance of belted shear tab connection and bolted top & bottom angle connection with considering the composite of slab exhibited in FEMA 355D. And the seismic performance by the effect of the composite slab is resulted Also, seismic performance of PRCC which can be used in Korea(weak-earthquake region) is evaluated and compared with that presented in FEMA 355D. This study leads the considerations of PRCC to secure the seismic performance appropriating in Korea and suggests the course of the studies to develop the PRCC after.
