Thin cylindrical shells in steel silos are subject to combined action of internal pressure and axial compression: at low levels of internal pressure, an axially compressed shell may fail by elastic buckling; at high levels of internal pressure, the axially compressed cylinder fails by plastic collapse.
钢筒仓中圆柱薄壳承受内压力和轴压力共同作用:在轴压和低内压作用下,壳可发生弹性失稳;在轴压和高内压作用下,壳可发生塑性破坏。
Experimental research and theoretical analyses on axial compression ratio of steel reinforced concrete special-shaped columns;
型钢混凝土异形柱轴压力系数限值的试验与理论分析
Limited values on axial compression ratio of steel reinforced high-strength concrete short columns;
钢骨高强混凝土短柱轴压力系数限值
Through 12 specimens experimentation study of steel reinforced high-strength concrete columns,it is analyzed the influence of slenderness ratio,axial compression ratio,stirrup ratio and steel form on the bearing capacity of columns.
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。
