Construction methods of large-span reticulated cylindrical shell are studied in this paper, based on variety of existing spacial structure construction methods. A new type of construction method that the structure is formed integrally by sliding support is bring forward in literature [1]. Construction process run-after computation is conducted by Ansys program, and a new type of hinged joint is obtained.

本文在概括总结了现有的各种空间结构施工方法的基础上，着重研究了大跨度柱面网壳结构的施工技术，对文献[1]提出的新施工方法——柱面网壳支座水平滑移结构整体成形施工法进行了施工全过程的跟踪模拟和结构内力分析，给出了具体施工实施方法，并提出了一种可单自由度转动的新型铰接节点。

In the analysis, a nonlinear wave vibration equation of the thin cylindrical shell including damping and items due to geometric nonlinearities was established and then transformed by Galerkin's method. With different combinations of modes different nonlinear differential equations in modal coordinates were obtained. The Runge Kutta method was used to solve the equations numerically and some features of nonlinear wave vibration were discussed.

在研究过程中，首先，考虑阻尼并引入几何非线性项，建立薄壁圆柱壳的非线性波动方程，然后，采用Galerkin方法对波动方程进行转换，选取不同的模态组合，得到相应模态坐标下的非线性微分方程，最后用Runge-Kutta法进行数值计算并对圆柱壳的非线性波动振动特性进行了分析。
