本文以多高层建筑为研究对象，分别应用反应谱振型分解法和时程分析法，分析了剪切型、剪弯型和弯曲型结构在不同地震烈度及不同场地条件下的地震基底内力及地震内力沿结构高度的分布．在分析比较各种不同分析方法所得结果的基础上，文中推荐这三类结构抗震分析的简化计算方法──底部内力法及地震内力沿结构高度分布的最大值包络曲线及公式．
In this paper, multiple high-rise buildings are taken as the research object, and the response spectrum-decomposition method and time-history analysis method are respectively applied to analyze the internal seismic base forces of shear, shear-bending and bending structures under different earthquake intensity and different site conditions. The distribution of internal forces along the structure in the earthquake. On the basis of analysis and comparison of the results obtained by various analysis methods, the simplified calculation methods for the seismic analysis of these three types of structures are recommended in this paper: the bottom internal force method and the maximum envelope curves and formulae of the internal force distribution along the structure.
