| 摘 要： | 在做出基本假定的情况下,通过分析钢骨高强混凝土柱截面中钢筋、混凝土和型钢的受力,确定出影响钢骨高强混凝土柱发生不同破坏形态的界限轴力,从而得出界限轴压比·在进一步针对轴压比的研究中发现,当钢骨高强混凝土柱截面中的型钢型号、混凝土等级、柱截面尺寸变化时,其轴压比的限值也是可变的,而不是一个定值·因此,在实际结构工程设计时应根据不同的情况采用不同的轴压比限值·

| Abstract: | On some assumptions, by analyzing the stress exerted on reinforced steel bar, on concrete and on section of steel reinforced high strength concrete column, the limited axial force which affects the damage form of steel reinforced high strength concrete column was examined. The limited values of axial compression ratio was calculated. The analysis of the axial compression ratio shows that the limited values of axial compression ratio vary with the size of the steel, concrete and column sections. Therefore the different limited values of axial compression ratio should be adopted in the engineering design according to specific applications. |
