In this paper, the author has found a problem concerning the stipu-lations of equivalent total gravity loads with base shear method that is stipu-lated in The Aseismic Design Code For Buildings(GBJ11-89). The equivalent total gravity load is defined by multiplying the total gravity load represen-tative value by equivalent mass coefficient 0.85 for multi-degree-of-freedom systems. On the basis of analyses and sample calculations, it is found that the coefficient of 0.85 is a little bit smaller for two and three-degree-of free-dom systems, especially, the difference is larger than 10 percent for two-degree-of freedom systems. The coefficient is proposed to be 0.95 when base shear method is used to calculate the horizontal earthquake effects for single-story factory building with different roof levels.

木文就《建筑抗震设计规范》(GBJ 11-89)中关于底部剪力法的等效总重力荷载的规定提出问题。所谓等效总重力荷载,对于多质点体系来说,就是总重力荷载代表值乘以等效质量系数0.85。作者通过分析及实例计算指出,对二、三质点系来说,该系数偏低,尤其对二质点系偏低误差超过10%;并建议,对不等高单层厂房,用底部剪力法计算厂房的横向水平地震作用时,取等效质量系数为0.95。

The concepts of the equivalent mass and the equivalent mass coefficient and the method to obtain them are presented, and then the more accurate equivalent mass coefficients of the elastic components or parts in several kinds of valve are calculated so as to provide the basis for the valve's design.
