基于能量标准的混凝土结构抗冲击设计

将冲击荷载分为软冲击和硬冲击，以受到软冲击作用的结构为研究对象，建立韧性设计方法的流程图。构思安全分析设计的思路，给出能量标准的安全系数概念，建立以能量标准对混凝土结构整体破坏进行安全校核的方法和准则，并以常见的混凝土板的冲击破坏为例，说明如何考虑破坏模式的影响。

Impact restsing design for concrete structures based on energy criterion

The study was performed on concrete structure design. The impact load was divided into soft impact and hard impact. With the structure under soft impact as the objective of study, the flow chart for toughness design method was drawn, and the idea for safety analysis design and concept of safety factor for energy criterion were put forward. Then, the method and criterion for safety checking of the integral failure of concrete structures based on energy criterion were established. With the impact failure of common concrete slabs as an example, the influences of failure modes on design result were described.
