摘要:
现有的经验方法无法准确计算同时传递竖向剪力和不平衡弯矩的钢筋混凝土板柱中节点的极限承载力.本文采用空间拉压杆原理将节点简化为由一系列钢筋拉杆及混凝土压杆组成的结构体系.以受拉钢筋和抗冲切元件屈服为标志,推导出了4种极限状态下中柱节点的极限承载力表达式,以此计算结果为基础可以作出相应的节点极限承载力折线图.与较多实验结果的对比证明该方法计算简便,结果合理,适用于工程设计.
Abstract:
The existing experimental method cannot accurately calculate the ultimate carrying capacity of the reinforced-concrete slab-column connections subjected to moment and shear. In this paper the spatial strut-and-tie model is used, and the connection is simplified as a structural system which is composed of a series of steel bars and concrete struts. The yield of steel bars and antipunching element is taken as the failure sign, and the strength expressions of four ultimate states of interior connections are analyzed. Based on the calculation results of the analyzed expressions, the ultimate shear-moment interaction diagrams for interior connections can be drawn. The comparison with a lot of experimental results proves that this method is convenient and reasonable and it is feasible in the practical design.
