摘要
以云南省昆明市某河闸为例,使用通用有限元软件SAP2000对河闸进行整体建模.除了最不利静力工况计算外,还使用反应谱法对河闸在地震工况下的抗震性能进行计算分析,得到河闸闸房框架的最小配筋率和层间位移角,并由此判断该河闸当前是否具备足够的抗震能力.
Sluice is a lifeline project; its aseismic performance is very important. Many of active sluices were built in the early stage of national foundation; the design and construction levels were lag behind at that time. Taking a certain river sluice in Yunnan province for example, 3D calculation model were established using FEM software SAP2000. Besides the worst-static load case, aseismic performance under earthquake load are calculated by means of response spectrum analysis. Minimum ratio of reinforcement and drift of sluice frame are obtained; and according to the results, it is concluded that the sluice is still available.
