随着四化建设的迅速发展,石油、汽油、化工容器等贮液罐,不仅数量剧增,容积也日趋大型化,已成为一种重要的特种结构。贮液罐设计除了要满足抵抗静水压力外,还必需考虑其抗御地震的能力。因此,贮液罐的抗震性能问题已被广泛重视。回顾历次强烈地震中,贮液罐的震害也是十分严 With the rapid development of the four modernizations, liquid tanks such as petroleum, gasoline, and chemical containers have not only increased in volume, but also have become larger and larger in volume, and have become an important special structure. In addition to the resistance to hydrostatic pressure, the tank design must also consider its ability to withstand earthquakes. Therefore, the problem of seismic performance of the tank has been widely considered. Recalling the strong earthquakes, the earthquake damage of the tank was also very strict
