组合结构撞击性能：火灾后钢管混凝土构件侧向撞击性能试验和数值研究

一、研究背景

钢管混凝土(Concrete-filled steel tube，CFST)具有优越的力学性能，良好的耐火性能和火灾后修复能力，近年来在建筑和桥梁结构等工程中得到广泛应用(图1a)。撞击作为一种偶然荷载，作用在结构上会导致与静态荷载作用时显著不同的结构响应，易造成结构损伤或倒塌，在一些极端情况下，结构会经历火灾和撞击的联合作用，如油罐车撞击桥梁后引发的火灾(图1b)，火灾下结构局部倒塌造成的冲击。钢管混凝土结构在服役期间不可避免地可能会遭受撞击和火灾等偶然荷载的作用，近年来研究者对CFST构件的抗撞性能进行了系列研究，但关于火灾下(后)CFST构件的抗撞性能研究十分有限。为此本研究进行了火灾后CFST构件侧向撞击试验和数值分析，并给出撞击响应的简化评估方法。

二、试验结果与讨论

共进行了9个火灾后CFST构件的侧向撞击试验，考虑了受火时间(th=0min、30min、60min、90min)，撞击高度(h=0.8m、1.5m、2.2m)和边界条件(两端固支、固-简支和两端简支)对撞击响应的影响。试验分两个阶段，包括火灾试验和侧向撞击试验，试验装置分别如图2和3。试验结果表明：随着受火时间增加，钢管表面逐渐由红褐色变为青色，受火90min的试件钢管表面氧化层大面积起泡和剥落(如图4)。火灾后CFST构件在侧向撞击作用下发生整体弯曲破坏，两端固支构件破坏区域主要在跨中和端部约束处，试件的整体弯曲和局部鼓曲随着受火时间的增加逐渐加重(如图5和6)。

三、有限元分析

采用ABAQUS有限元软件建立受火后CFST构件的侧向撞击有限元模型(如图11)，通过试验结果对模型的准确性进行验证(结果对比如图5、6和7)，结果表明建立的火灾后CFST构件的侧向撞击有限元模型可以很好地预测撞击力时程曲线和试件的破坏模态。

基于建立的有限元模型分析了受火后CFST构件的撞击响应和轴向加载的影响，结果表明：钢管对受火后CFST构件的动态抗弯承载力贡献显著高于混凝土，不同受火时间下(0min-90min)钢管的动态弯矩平均占整个截面的74.2%(如图12)；当轴向荷载比小于0.3时，轴向荷载的变化对构件的侧向撞击响应影响很小(如图13)。
