中文摘要：
通过计算钢-混凝土复合防护板在弹体冲击作用下的动力响应过程，分析研究了复合板的耐冲击性能。首先计算单层混凝土板的情况并与经验公式结果进行比较，验证了本文方法用于计算该类结构动力响应的可靠性。通过计算不同混凝土厚度、不同弹体速度和不同防护结构形式的动力响应，具体分析了冲击过程三阶段中钢．混凝土复合板的响应特性，并给出了不同弹体初始速度情况下复合板的主要破坏形式。研究表明，与相同条件的单层混凝土相比，钢．混凝土复合防护板可以有效地防止穿透，其耐冲击能力提高60％，可为工程防护结构的安全设计提供技术依据。
英文摘要：
In this paper, the performance of steel-concrete composite slabs under impact loads has been studied on the basis of calculating the dynamic response. The penetration limit thicknesses of single concrete are obtained by FEA method, and the comparison of the simulation results with that from the experiential formulas verifies the rationality of FEA method. By calculating the dynamic response of different concrete thicknesses, various impact velocities and different defense structures, the characteristic of three stages in the steel- concrete composite slabs has been analyzed, and the main damage forms of the composite slabs are also given. It is showed that the steel- concrete composite slabs could prevent the penetration effectively, and the anti-impact capability could increase 60% , which are resultful for the design of the defense wall.
