为研究低周反复荷载作用下框架梁柱边节点的抗震基本性能,采用OpenSees通用分析软件对框架梁柱节点进行了非线性数值模拟。结果表明,数值模拟结果和现场试验检测结果一致性较好,两者误差均小于10%,表明所选取材料的参数以及材料的本构关系,具有较好的合理性和适用性,OpenSees可很好地模拟框架梁柱节点在往复荷载作用下的滞回曲线和骨架曲线。
In order to study the basic seismic performance of frame beam-column joints under low-cycle repeated loading, the OpenSees general analysis software was used to conduct nonlinear numerical simulation of frame-beam joints. The results show that the numerical simulation results are in good agreement with the field test results, and the errors between the two are less than 10%. It shows that the parameters of the selected materials and the constitutive relations of the materials have good rationality and applicability. OpenSees can be very The hysteresis curve and the skeleton curve of the beam-column joints under cyclic loading are well simulated.
