摘　　要：采用连续化假定,把框架、剪力墙结构抗侧单元当作计及剪切变形的梁,通过弹性楼板的协同分析,建立了大底盘多塔结构二阶分析的哈密顿对偶体系,用精细积分法求该体系的高精度数值解,给出了考虑楼板变形时一套分析大底盘多塔结构二阶效应的方法。The author adopts continuous assumption, regards frame and shear wall structure lateral unit as the beam of shear deformation, establishes Hamilton dual system of the second-order analysis on the large-chassis-mount multi-tower structure based on the cooperative analysis of the elastic floor. By using precious integration method, the author gets the system＇s highly accurate numerical solution, provides a set of methods about analyzing large-chassis-mount multi-tower structure second-order effect with consideration of floor deformation.
