| 摘 要： | 针对带加强层的框-筒结构体系，为考虑普通楼层梁的影响将其等效为沿竖向分布的连续介质，同时计入加强层梁、核心筒、普通楼层梁、外框柱的剪切应变，推导出了顶部设置加强层的框筒结构在水平荷载作用下应变能的表达式，为推导此类结构在水平荷栽作用下的侧移打下了基础，同时也为求解此类结构在水平荷载作用下的内力提供了方便。

| Abstract: | This paper analyzed the high-rise frame-tube structure with strengthened stories and proposed a strain energy calculating method of top-strengthened structure under lateral load.Considering the contribution of the floor beam,the frame-tube structure with strengthened stories was simplified into continuous medium along the height by using continuum theory,taking the shear strain energy of strengthened girders,core wall, floor beams,and columns into account.Finally,the analytic expression of the strain energy of this structure was abtained in terms of the height.The conclusion provided much convenience to deduce the sideway and get the internal forces of such structure under lateral loads. |
