摘要:针对钢管混凝土结构构件在爆炸冲击荷载作用下的动力响应进行研究,试验对象为相同管径三种不同壁厚的钢管混凝土结构构件在简支状态下,受到两种不同爆炸冲击荷载的作用,测量了两种不同爆炸空气冲击波的压力时间曲线、构件跨中的应变时间曲线和构件跨中的最终挠度值,并对测量结果进行分析,为钢管混凝土构件的抗爆炸荷载设计提供有益的试验成果,也为后续进一步研究提供有效的基础数据和可靠的对比参照。

Abstract:The dynamic response of concrete filled steel tubular subjected to blast load are studied. The subjects are concrete filled steel tubular of three different wall thickness and the same diameter on two different blast loads. The tests were carried out two different dosage of explosive detonation and the blast wave pressure-time curve, the strain inter-time curve in the bottom of component and the final deflection of component are measured. At the same time, the measurement results are analyzed. The results provides a useful test reference for the anti-blast loading design on concrete filled steel tubular and the effective data for the further follow-up studies.
Key wordsconcrete filled steel tubular;blast load;strain;deflection
