摘要

吕梁新城体育中心体育场采用中部大开孔单层网壳,由于跨度与中部开孔较大,在静力作用下稳定问题较为突出。利用ABAQUS软件建立网壳整体模型进行非线性全过程分析,并选取初始几何缺陷与支座约束条件对网壳进行参数化分析,研究网壳结构稳定性能。分析结果得出工程所采用的大开孔单层网壳整体稳定性能良好,符合规范限值要求。
        The stadium of Lüliang New City Sports Center adopts a single-layered latticed shell with large opening. Due to the large span and the central opening, the stability problem is prominent under the action of static force. The ABAQUS software was used to establish the overall model of the latticed shell for nonlinear whole process analysis. And the initial geometric defect and bearing constraint was selected to carried out parametric analysis of the latticed shell and the stability of the latticed shell structure was explored. The analysis results show that the large-opening single-layer latticed shell used has good overall stability and meets the requirements of code limit.
