摘要
根据现阶段大量出现的混凝土结构上加盖轻钢结构的结构形式特点,采用子结构方法分别对原有混凝土结构和加层钢结构的质量、刚度和阻尼矩阵进行叠加,进而运用实模态振型分解法求解结构地震反应,通过本文方法与Newmark时程法的比较研究表明,本文方法具有相当的精度。
According to the characteristics of the light steel structure of added story, a new mode-superposition method is presented. The quality, the rigidity and the damping matrix of the original concrete structure and the light steel structure of added story are superimposed separately using substructure method, and then the seismic response of the structure is resolved. And the result proves that this method comparing with Newmark-method has considerable precision.
