摘要
本文通过12个钢纤维混凝土框架边节点的试验,研究了这种节点的破坏过程、抗裂强度、抗剪强度及剪切延性等问题;给出了节点抗裂强度及抗剪强度的计算公式;并建议以剪切延性作为评价节点抗震性能的指标之一。
According to the experimental results of 12 exterior joint speciments for SFRC frames,the failure process, the crack strength, the shear strength and the shear ductility of the exte-rior joints were investigated in this paper. The farmulas for calculating the crack strengthand the shear strength of the exterior joints were also given respectively. In addition, it issuggested that the shear ductility can be used as an index to estimatc the aseismic behaviorof the joint in RC frames.
