具有大型污水池的多层结构的水平抗震计算

Horizontal Aseismatic Calculation of a Multi-story Structure with Large Sewage Pools

在《建筑抗震设计规范)GBJ11-89中,对具有大型污水池的多层结构的水平抗震计算没有明确的规定,使得在实际工程设计中进行水平抗震计算的随意性很大,存在很大的安全隐患。本文提出了计算具有大型污水池的多层结构的水平抗震计算方法。文中指出,在计算具有大型污水池的多层结构的水平地震作用时应考虑污水池中污水的晃荡力或称污水引起的附加地震作用。文中提出了计算附加地震作用的公式和计算附加质量系数的方法,并用一个工程算例演示了这种计算方法。

The stipulations of horizontal aseismatic calculation of a multi-story structure with large sewage pools are not clear in 《Building Aseismatic Design Codes》 GBJ11-89. In practical engineering designs, there are unsafeties and randomizations. The methods of horizontal aseismatic calculation of a multi-story structure with large sewage pools were presented. Sewage's swinging forces or additional earthquake actions should be taken into account in calculating horizontal earthquake actions of a multi-story structure with sewage pools. Formulae of calculating additional earthquake actions and methods of calculating additional mass coefficients were presented, which are illustrated by an engineering example.
