摘要
弯矩调幅法作为一种在弹性分析基础上考虑结构内力重分布的简化计算方法,在工程实践中得到了广泛的应用。为此,简述了钢-混凝土连续组合梁三种不同的弯矩调幅系数确定方法,并通过算例比较了不同弯矩调幅系数对组合梁承载力的影响。对组合梁结构优化设计具有参考价值。
Moment modulation method has been widely applied in engineering practices as a simpli-fled calculation method which takes accordance of structural internal force redistribution on the basis of elastic analysis. In this paper, three different methods of determining moment modulation coefficient were briefly introduced, and an example was presented to analyze the influence of various values of moment modulation on bearing capacity of composite beams. The conclusion has reference value for structural optimization design of composite beams.
