Seismic performance analysis of reinforced-concrete-frame joints after fire
Reinforced concrete frame joints (RCFJ) under(after) fire are analyzed by ABAQUS. Joints are heated under dead load by ABAQUS. Subroutines mtemp was programmed to record the highest temperature which nodes experienced. Then the highest temperatures will be put to joints as predefined temperature field by subroutines utemp after high temperature. Load is applied by displacement control. Material's nonlinearity and the bond-slip between reinforced and concrete are both considered. The stress distribution of joints' core is accurately analyzed after unit-choose and meshing precisely, seismic performance of RCFJ are analyzed under statically cyclic load, which is in accordance with experimental results.
