钢筋混凝土高架式贮仓是许多工业部门广泛使用的工业构筑物。国内已建成的贮仓其每一仓格的容积达到10,000米~3,高度在40-50米左右者已很多见,少数仓的高度已超过50米,从发展来看,容量与高度还会进一步增大,如国外有的贮仓每一仓格的容积已达30,000米~3或更多。大荷载、高重心、质量和刚度分布很不均匀是高架式贮仓的特点,也是它在抗震性能上的弱点,由于工艺上的需要,这还不易改变。我国自邢台地震以来,尤其是海城地震和唐山地震对于钢筋混凝土高架式贮仓震害
Reinforced concrete elevated storage silos are industrial structures widely used in many industrial sectors. The warehouses built in China have a capacity of 10,000 m-3 per cell, and the height is about 40-50 meters. The number of warehouses is more than 50 meters. From the perspective of development, the capacity and height will be Further increase, such as foreign warehouses have a capacity of 30,000 meters to 3 or more per bin. The uneven distribution of large loads, high center of gravity, mass and stiffness is a feature of elevated silos, and it is also a weak point in seismic performance, which is not easily changed due to process needs. Since the Xingtai earthquake in China, especially the Haicheng earthquake and the Tangshan earthquake, earthquake damage to reinforced concrete elevated storage silo
