| 摘 要： | 现浇整体式混凝土节点J1、预制结构装配整体式普通混凝土节点J2和不同体积含量的钢纤维混凝土节点J3、J4在低周反复荷载作用下的足尺寸模型对比试验结果表明，核心区采用钢纤维混凝土可以提高节点的抗裂能力和受剪能力。在试验结果和计算分析的基础上，对已有钢纤维混凝土节点抗剪公式提出建议，给出了预制结构钢纤维混凝土节点的抗剪强度实用公式，为工程设计和相关研究提供依据和参考。

| Abstract: | The result that the addition of steel fiber can efficiently enchance cracking strength and ultimate strength is got by comparing experiments on three types of full-scale models:monolitic joints,concrete and steel-fiber filled precast concrete joints under low reversed cyclic loading.Based on the experiment result and computations analysis in this paper,ultimate load calculative formula of steel fiber reinforced concrete corbels is put forward.It will provide references for engineering design and scientific research. |
