【摘要】 球面网壳结构由于受力合理、用料经济、造型美观,能覆盖较大空间,近十年来发展速度很快,其发展前景广阔,是一种理想的空间结构形式。本文以包头市某120 m双层球面网壳这一实际工程为背景,应用ANSYS软件分析该大跨度双层球面网壳结构的动力特性,得出一些具有参考价值的结论。更多还原

【Abstract】 Spherical reticulated shell structure attributed to its reasonable under loading performance,economical material consumption,slinky sculpt and capability of large spanning,has rapidly developed in the last decades.It has become an ideal spatial structural form due to its capacious development and engineering application.This thesis takes on a practical project of double-layer cable-dome spherical reticulated shell structure,covering a span of 120 meters in Baotou city.The dynamic properties of double layer spherical reticulated shell are analyzed by ANSYS software,and some practical conclusions are drawn in this paper.更多还原
