摘要:
在分析影响空间钢构架约束作用主要因素的基础上,采用有效约束系数ke,综合考虑空间钢构架对梁柱节点域混凝土的约束作用。在分析已有试验结果的基础上,提出了空间钢构架约束混凝土的抗压强度fcc的计算公式。根据空间钢构架混凝土梁柱节点试验结果,提出了考虑约束作用的空间钢构架混凝土梁柱节点域受剪承载力Vu的计算公式,计算值和试验值吻合较好,为这种新颖梁柱节点的工程应用提供依据。
Abstract:
Based on analyzing the main factors which affect constraints of the spatial steel frame, the constrain function of spatial steel frame on beam-column joint concrete was considered by using effective constraint coefficient. Through analyzing the existing test results, the calculation formulae of the confined concrete compressive strength by spatial steel frame was put forward. According to the test results of spatial steel frame concrete beam-column joints, the calculation formulae of the shear bearing capacity of the spatial steel frame concrete beam-column joint region considered constraint effects was proposed. The calculated results were agreed well with the experimental results, which provides the basis for this new type beam-column joints of engineering application.
