摘要
文章从型钢混凝土柱界限破坏的内力平衡条件出发,推出了配工字形和配十字形型钢的型钢混凝土柱的轴压比限值理论计算公式,并与国内现有的试验结果相比,吻合较好,简化后给出了其实用计算公式。计算结果表明,与普通钢筋混凝土柱的轴压比限值相比,配置工字形型钢的混凝土柱的轴压比限值不能显著提高,配置十字形型钢的混凝土柱的轴压比限值提高,效果较好。
Based on the balanced condition of internal forces in the case of balanced failure, the theoretical calculation formulas of limit values of axial compression ratio for steel reinforced concrete columns are derived. They are in accordance with the existing test results in China approximately. Meanwhile the practical calculation formulas are put forward by simplifying the derived formulas. The calculated results show that the limit values of axial compression ratio for steel reinforced concrete columns with cross-shaped steel can be raised to a higher level in comparison with the common reinforced concrete columns, however the limit values of axial compression ratio for steel reinforced concrete columns with I-shaped steel can not be raised remarkably.
