摘　　要：工程结构在服役期间可能承受重物连续坠落和结构连续垮塌等多次冲击作用,冲击荷载作用下,钢板能有效阻止撞击物贯穿,混凝土芯材能够承担耗能层。因此,文中研究了一种轻钢泡沫混凝土复合楼板的多次冲击行为,从抗弯抗剪能力、震动舒适度等方面对这种复合楼板进行了深入研究,结果表明,该复合板具备良好的强度,还能提高施工效率,实现节能环保,降低生产成本。在此基础上,文中还分析了这种复合楼板在受到冲击时的临界状态。Engineering structures may be subjected to multiple impacts such as continuous fall of heavy objects and continuous collapse of structures during service.Under impact loads,steel plates can effectively prevent impactors from penetrating,and concrete core materials can bear energy-consuming layers.Therefore,this paper studies the multiple impact behavior of a light steel foamed concrete composite floor.A lot of research has been done on this composite floor in terms of flexural and shear resistance,vibration comfort and so on,proving that it has good strength,and it can also improve construction efficiency,promote energy saving and environmental protection,and reduce production costs.On this basis,the critical state of the composite floor under impact is studied.
