接触爆炸荷载下钢—混凝土组合梁简化设计方法研究

Research on the simplified design method for steel-concrete composite beam subjected to contact blast loading

接触爆炸荷载作用下可引起结构的破坏。为研究钢—混凝土组合梁的抗爆性能,基于等效单自由度方法和能量方法,推导了接触爆炸荷载作用下钢—混凝土组合梁最大弹塑性变形的简化计算方法,并同数值分析结果进行了对比。结果表明,此方法有较高的计算精度,可用于评估钢—混凝土组合梁的抗爆能力,并可供实际工程参考使用。

The structures subjected to contact blast loading are easy to failure. In order to understand the knock characteristics of steelconcrete composite beam, a new design method that is the energy method of single degree of freedom model is set up. The compared results between numerical analysis and the above design method show that the new method can be simply used well for practical project.
