摘要：

To investigate the seismic behavior of ultra high toughness cementitious composite (UHTCC) reinforced beam-column joints, eight local enhancement beam-column joints and one control beam-column joints were tested under constant axial load and cyclic lateral force. Influence of axial compression ratio, stirrup characteristic value and the pouring range of UHTCC were analyzed. Results show that calculation result based on the OpenSees finite element has good agreement with the test results, and UHTCC material can significantly control the crack at joints area. Higher axial compression ratio can increase the shear capacity of nodes but will reduce its deformation capacity. Stirrup characteristic value is proposed to be set between 0.07 to 0.10 for the need of ductility and the characteristics of convenient construction. ©, 2015, Huazhong University of Science and Technology.
