提出一种用于钢-混凝土混合连接的非线性有限元分析方法。考虑了部分抗震设计的四个足尺钢-混连接点的详细的试验结果已在另一篇论文中予以讨论。然而,由于梁柱节点和试验构件特性的内在复杂性,试验研究是不够全面的。因此,提出了一种基于有限元模型和DIANA程序的分析方法。有限元模型通过新加坡南洋理工大学钢-混凝土混合连接的试验结果证实有效。对于影响节点性能的参数,如柱子的轴压力、连接板厚度、梁底部纵筋进行了研究。
A nonlinear finite element method for steel-concrete hybrid connection is proposed. Detailed test results of four full-scale steel-concrete joints considering some seismic designs are discussed in another paper. However, due to the inherent complexity of the characteristics of beam-column joints and test components, experimental studies are not comprehensive enough. Therefore, an analysis method based on finite element model and DIANA program is proposed. Finite element model through the Nanyang Technological University in Singapore steel-concrete hybrid test results proved effective. The parameters affecting the performance of the joints, such as the axial pressure of the column, the thickness of the connecting plate and the longitudinal reinforcement of the bottom of the beam, were studied.
