摘要
大跨度及高层空间结构是目前发展最快的结构类型。大跨度建筑及作为其核心的高层空间结构技术的发展状况是代表一个国家建筑科技水平的重要标志之一。本文主要研究变截面均质悬臂梁的结构体系在水平均布荷载作用下的静力分析,以及EULER悬臂梁的自由振动分析。根据哈密顿原理推导出控制方程和边界条件,然后用常微分求解器COLSYS进行求解。
Large span and the tall building spatial structure is now the fastest -growing structure types. The development of Large span buildings and the tall building structure technology is representing a national science and technology level In this article, we mainly study the static analysis of the structure of variable cross - section cantilever system under the average distributed loadings, and the free vibration analysis of cantilever EUL- ER. According to Hamihonian principle, we can deduce Governing equations and Boundary conditions, then solve it by using differential COLSYS solver.
