| 摘 要： | 对超高层建筑空间巨型框架提出一个考虑水平力与重力相互影响的二阶效应的分析方法。将空间巨型框架简化为三维压杆巨型柱和弹性地基上的巨型梁的组合 ,二级框架柱考虑其轴向变形作为巨型梁的弹性地基 ,按空间压杆 弹性地基梁刚架进行水平力与重力共同作用的二阶分析。为超高层建筑空间巨型框架提供一个合理、简化的二阶分析方法

| Abstract: | A simplified method of the second order effect between gravity and horizontal forces for super tall building space mega-frame is given.The space mega-frame is seen as a space composite system of 3-dimensional pressure mega-column and mega-beam lying on elastic foundation,in which the secondary frame columns considering its axial deformation is seen as the elastic foundation.The gravity second order effect is analyzed for this space mega composite system. |

| Keywords: | skyscraper mega-frame 3-dimensional pressure member beam elastic foundation second order analysis |
