开孔钢筋混凝土板的静力与冲击性能数值分析

摘要

The reinforced concrete slab with hole was built in the finite element software ANSYS,displacement,stress and dynamic response were analyzed to concrete slab with different hole under static and impact loadinf,it was concluded that the law of displacement and stress distribution. And some basis were provide to how to reinforcinf bar reasonably and effectively around the hole.%采用有限元软件 ANSYS，建立了开孔钢筋混凝土板模型，对不同孔洞位置和大小的钢筋混凝土板在静力和冲击荷载作用下的挠度、应力以及动力响应进行了研究，得出的结论为楼板开洞时在洞口周围合理、有效地配筋提供了依据。
