超高层建筑空间巨型框架的稳定计算

STABILITY ANALYSIS OF HUGE SPACIAL FRAME STRUCTURES OF SUPER TALL BUILDINGS

  • 摘要: 对超高层建筑空间巨型框架的稳定计算提出了一个新的简化计算模型,将空间巨型框架简化为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,按空间刚架进行稳定计算.由算例的计算结果来看,简化模型及其分析方法是合理的,为超高层建筑空间巨型框架结构的整体稳定计算提供了一个合理可行的简化计算方法.

     

    Abstract: A new simplifying model for the stability analysis of huge spacial frame structures of super tall buildings, is presented in the paper. The huge spacial frame structure is simplified as an assemblage of its huge columns and huge elastically supported beams whose elastic supports is provided by the axial stiffness of its accessorial columns. The stability analysis based on the spacial rigid-joint frame structure is performed. The results are shown to be reasonable. Therefore, the model and method will supply a reliable and feasible computing approach for stability analysis of super tall buildings with huge spacial frame structures.
