摘　　要：智能建筑的大量出现 ,其中的辅助设施越来越多 ,也越来越复杂 ,导致很多管路、线路、电梯都是从楼板中开孔穿过 钢筋混凝土板开孔后受力性能会发生改变 ,孔的周围出现应力集中 用有限元分析了四边固支开孔板在不同开孔位置和形状 ,不同开孔面积的情况下内力的改变 ,获得了内力改变的规律 ,并和三边固支板、悬挑板在近似的边界条件下的受力情况进行比较 ,得到一些相近的结果 。With the advent of intelligent buildings, more complicated facilities are required. At the same time, many pipes, lines and elevators have to go through floors by openings. The reinforced concrete plate changes its mechanical behavior after openings and stress concentration will appear around the opening. By using finite element method, fixed Supported Square Plates with openings for different location and size of the openings are investigated. The mechanics rule of plates after openings are presented. A comparison is made for the above plates and the plates supported in three sides and the cantilever of plate in approximate boundary conditions. Some approximate results are obtained. Several design suggestions are presented for later engineering practice.
