摘要
带有轻钢增层的结构，质量与刚度在房屋的增层处出现明显减弱，在地震反应中高阶振型的影响较为显著，为此，采用振型分解法分析了在高阶振型组合影响下，轻钢增层结构的地震反应，对采用底部剪力法进行抗震设计时，动力放大系数的合理取值进行了计算与分析。
The mass and rigidity of the structures with added light steel storeys decrease obviously at the added storey. The influence of high modes is remarkable in the seismic response. Using the vibration model resolving method, the seismic response of the added light steel storeys is analysed under the influence of high modes. For the aseismic design with the bottom shear method, it is calculated and analysed to obtain the reasonable value of dynamic amplifying coefficient.
