ABSTRACT

This paper aims to present a numerical nonlinear spring model able to simulate the cyclic behavior of the monolithic and the precast bolted reinforced concrete beam-column connections with the consideration of the concrete interface friction and the dowel action of reinforcing steel bars. The accuracy of this proposed model was verified by the comparison with some existing experimental test results. Generally, these comparisons showed good agreement and the model could simulate the cyclic performance of the tested specimens. Also, a study of the effect of increasing the area of shear reinforcement at the shear key zone was performed and discussed.

循环荷载作用下预制钢筋混凝土梁柱节点的建模

摘要

本文旨在提出一种数值非线性弹簧模型，该模型能够模拟整体式和预制螺栓连接钢筋混凝土梁柱连接的循环行为，并考虑混凝土界面摩擦和钢筋的销钉作用。通过与现有的一些实验测试结果进行比较，验证了该模型的准确性。一般来说，这些比较显示出良好的一致性，并且该模型可以模拟测试样品的循环性能。此外，还对增加抗剪关键区域抗剪钢筋面积的影响进行了研究和讨论。
