UHTCC局部增强框架节点抗震性能试验
Experiment of seismic performance of UHTCC reinforced beam-column joints
摘要
Abstract
To investigate the seismic behavior of ultra high toughness cementitious composite (U HTCC) reinforced beam‐column joints ,eight local enhancement beam‐column joints and one con‐trol beam‐column joints were tested under constant axial load and cyclic lateral force .Influence of axi‐al compression ratio ,stirrup characteristic value and the pouring range of UHTCC were analyzed .Re‐sults 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 com‐pression 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 charac‐teristics of convenient construction .关键词
