摘要:
针对在矩形钢管混凝土柱楼层节点区钢管内设置分配梁和内环肋这种节点新形式,研究分析该设置传力构件的矩形钢管混凝土柱轴压荷载作用下的受力机理,揭示其能有效协调钢管壁与内部混凝土的变形与受力,迫使钢管壁与内部混凝土共同承受外荷载的功效.试验验证表明,节点设置传力构件改善了矩形钢管混凝土柱的受力性能,在此基础上提出了传力构件分配梁的设计方法.
Abstract:
A new form of concrete-filled rectangular steel tube column joint is analysed. This said joint involves arranging force transmission components, that is, the distribution beams and inner periphery ribs at floor node zone. It is explored that the force transmission components can coordinate the force and deformation of exterior rectangular steel tube and internal concrete and force steel tube and concrete to carry external loads together. The exiting test results show that arranging force transmission components can improve the bearing performance of CFRT. Finally, the design method of force transmission component distribution beam is proposed.
