摘要
以固支的圆板为例,建立了三角形冲击荷载作用下钢筋混凝土的有限元模型,分析了荷载大小和作用时间对板动力响应的影响,结果表明,板的动力响应主要受荷载强度的影响,荷载作用时间影响不大,结构变形以弯曲模态为主。
The finite element model of a circular RC slab under triangular impact loading was established in the article. The effects of loading magnitude and duration time on the dynamic response of the slab were analysed. The result showed that the slab＇ s respons was mainly influenced by loading magnitude in comparison with duration time. Bending was the main transformative mode.
