摘要
采用非线性有限元分析方法,在低周反复荷载作用下,对四榀不同加腋宽度的梁端水平加腋偏心节点构件的受力性能进行分析,探讨不同加腋宽度下节点核芯区受力性能及梁端塑性铰转移条件,并将有限元分析结果与试件实际受力状态进行比较,在理论分析和试验研究的基础上,给出了梁端塑性铰位置识别方法。
The strain characteristics and crack patterns of four specimens of reinforced concrete eccentric beam-column joints with spread-ended beam under reversed cyclic loading are investigated by using the nonlinear finite element method. The performance of the joints are studied as the width of the spread-ended beam varies,and the conditions of displacement of plastic hinge at the end of the beam are discussed. The results of finite element analysis are compared with the actual failure situation of the specimens,and the method of determining the position of the plastic hinge is presented.
