【提要】 通过12根钢骨高强混凝土柱的承载力试验,分析了长细比、轴压比、配箍率及钢骨形式对柱受力性能的影响,发现钢骨高强混凝土柱的受力性能除对轴压力系数、长细比敏感外,钢骨形式也是一个重要的影响因素,对于钢骨形式不同的钢骨高强混凝土柱,可适当调整其轴压力系数限值。还从理论上分析了试件的稳定承载力和轴压力系数,结论与试验结果吻合较好,所得结果可用于指导工程实践。

Abstract:Through 12 specimens experimentation study of steel reinforced highstrength
concrete columns,it is analyzed the influence of slenderness ratio,axial compression ratio,stirrup ratio and steel form on the bearing capacity of columns.It is found that the bearing capacity of columns is influenced by not only axial compression ratio,slenderness ratio,but also steel form. So the axial compression ratio of steel reinforced highstrength concrete columns with different steel form can be adjusted. The specimens' stability bearing capacity and axial compression ratio in theory are analyzed and the conclusion is
identical with the experimental results.
Keywords:steel reinforced highstrength concrete; column; axial compression ratio; slenderness ratio
