摘要:
对RCS平面、空间组合节点进行弹塑性有限元对比分析，表明了，空间组合节点的承载力比平面节点提高约17%，因此，仅套用现有RCS平面组合节点承载力的公式计算空间组合节点是不合适的. 在此基础上，进一步探讨空间节点各构造措施的受力状态及其对承载力的贡献，并分析混凝土强度、楼板厚度、楼板宽度和钢梁腹板厚度等参数对RCS空间组合节点承载力的影响. 根据受力机理和参数分析的结果对平面组合节点的承载力公式进行改进，结果表明，改进公式可有效地计算包含楼板、直交钢梁、柱面钢板和扁钢箍等构件或构造措施的RCS空间组合节点的抗剪承载力.
Abstract:
Elastic-plastic finite element analysis was carried out on the RCS composite joints in 3D and plane, it is concluded that the bearing capacity of three-dimensional composite RCS joint 17% higher than the plane composite RCS joint. So we can′t apply the existing formula for calculating the bearing capacity of the RCS composite joints in plane to calculate the bearing capacity of the three-dimensional composite RCS joint. On the basis of the above research, analyzed the influence of concrete strength, slab thickness, slab width, and steel beam web thickness to the bearing capacity of the three-dimensional composite RCS joint model. According to the parameter analysis results to improve the ASCE suggested formula and compared it with the simulation results, it turned out that the improved calculation formula for the bearing capacity of the three-dimensional composite RCS joint has a high precision.
