摘要:
在SRC柱-RC梁混合节点试验的基础上,采用通用有限元分析软件Ansys,建立考虑材料非线性的有限元分析模型.在单调加载作用下,对6个SRC柱-RC梁混合节点进行非线性数值模拟.改变梁纵筋配筋率和节点核心区配箍率,通过对荷载-位移曲线的分析,并与试验结果的对比,研究强节点系数对SRC柱-RC梁混合节点的破坏形式、承载力、延性等影响.结果表明,有限元模拟得到的荷载-位移曲线与试验结果吻合较好,从而验证采用有限元数值模拟开展SRC柱-RC梁混合节点研究的可行性.
Abstract:
Based on the experimental results of steel reinforced concrete(SRC) column-RC beam hybrid joints,the finite element model considering material nonlinear is established by Ansys software.Nonlinear numerical simulation of six SRC column-RC beam hybrid joints under the monotonic loading is carried out.According to the analysis of load-displacement curves and comparison with experimental results,the influence of strength ratio of joint to beam on the failure modes,strength and ductility of specimens is investigated for different longitudinal reinforcement ratios of beam and stirrup ratios of joint core.The analysis results indicate that the load-displacement curves of six specimens are in good agreement with the experimental results,so the finite element numerical simulation of SRC column-RC beam hybrid joints is feasible.
