| 摘 要： | 钢结构与混凝土结构阻尼比不同,混凝土房屋与其顶上钢塔组成了非比例阻尼结构系统。本文用非经典振型分解法求解该类结构系统的线弹性地震响应,发现只用前几阶振型响应迭加的结果即可逼近直接积分法的精确度。

| Abstract: | The damping ratio of steel structures and RC structures are different.A reinforced concrete building with a steel tower atop it composes a non-proportional damping system.The non-classical modal superposition method is used for the elastic earthquake response analysis of this system in this paper.An example is calculated,and it is found that a few modes can provide sufficiently accurate results compared to the direct integration method. |

| Keywords: | non-proportional damping modal superposition reinforced concrete steel tower earthquake response |
