| 摘 要： | 本文在推导钢 压型钢板混凝土组合梁极限抗弯承载力计算公式的基础上，验证了简化计算方法的可行性。通过对笔者完成的 5根钢 压型钢板混凝土组合梁试验结果的计算分析，提出栓钉间距对其抗剪承载力的影响系数β。本文公式计算结果与国内外 26根试验梁的实测值吻合良好。根据本文研究成果，可以很方便地得到考虑钢 压型钢板混凝土组合梁组合作用的极限抗弯承载力。

| Abstract: | In order to study the plastic behavior of continuous composite beams with profiled sheeting, experiments have been conducted on three specimens of two span continuous composite beams with profiled sheeting. The test results show that the negative bending regions of continuous composite beams have sufficient plastic rotation ability and ductility to develop full moment redistribution by controlling the parameter of force ratio R. Based on the test results, theoretic method for calculating the ultimate amount of redistribution moments is developed. The proposed formulae for the moment redistribution ratio are valuable to the design of continuous composite beams. |
