摘要
通过落锤冲击实验,对固简支钢管混凝土柱在侧向冲击荷载作用下的动力响应问题进行了研究,分析了钢管壁厚、落锤冲击高度对最大冲击力、冲击力作用时间及构件挠度值等因素的影响,为钢管混凝土构件耐撞性能的研究提供了依据。
In this paper, drop hammer impact test is done to the fixed-freely-supported steel pipe concrete under the lateral impact to study the dynamic response, and the pipe wall thickness, the height of the drop hammer are how to affect the biggest impact load, effect time and deflection and so as factors are analysised, the study provides a basis to the steel pipe concrete＇s crashworthiness performance.
