钢筋混凝土框架圆柱节点抗震抗剪强度的试验研究

Experimental Study of the Shear Strength of Reinforced Concrete Frame Beam-cylinder Joints Under Low Reversed Cyclic Loading

本课题为国内首次进行的钢筋混凝土框架圆柱节点抗震的试验研究。本文进行了六个钢筋混凝土圆柱中节点在低周反复荷载作用下的试验。采用塑性理论推导了核心区极限承载力的理论公式,结合试验结果,建立了节点铁心区抗剪强度的实用计算公式。本试验研究有一定的理论模式,可为工程设计和科学研究提供依据和参考。

This subject is the first expcrimental study on seismic resistance of reinforced concrete frame bcam-cylinder joints in our country. The theoretical formulas of caculation for ultimate shear strength of core region arc sct up according to the plastic thcories. Bascd on the expcriments of six beam-cylinder interior joints under low reversed cyclic loading,the practical formulas arc also proposed.This paper provides bases and references for structural design and scicntific rescarch.
