摘要
首先利用底部剪力法分析了多层剪切型框架结构的地震作用与质量和刚度变化的关系,进而研究了由于填充墙数量和位置的变化而引起结构质量和刚度的变化情况,指出对应质量和刚度上限的完全填充状态是地震作用的最不利状态,提出了计算填充墙框架最不利地震作用的包络设计方法。
The relationship between earthquake action and the changes of mass and rigidity is analyzed with the equivalent base shear method. The variation in number and location of infilled walls resulting in changes of mass and rigidity of structures is studied. The full-filled state corresponding to the upper limits of mass and rigidity is the most disadvantaged. The seismic envelope design methods of frame structures with infilled walls are given.
