现代空间钢结构形式多样、受力复杂、规模庞大,采用何种成本合理、安全可靠的施工方法实现其建造十分关键.介绍了空间钢结构施工的典型特点,对目前在空间钢结构施工中应用较多的滑移等、提升、张拉整体成形、累积旋转、整体起扳及折叠展开成形等施工方法的工作原理、适用范围和结构形式等进行了分析.空间钢结构施工不仅要确保施工过程的每一个状态下构件强度不超标和结构整体稳定可靠,同时还应将施工在结构构件中产生的附加内力或残余应力控制在较低的合理水平.
The steel structure of modern space is diverse in form, complicated in force and large in scale, and it is very crucial to adopt a reasonable and safe construction method to realize its construction.The typical features of space steel structure construction are introduced, and the application of space steel structure construction More slip, etc., the overall shape of the tension, the cumulative rotation, the overall pull and the folding start forming methods such as working principle, scope and structure of the form were analyzed.Step steel structure construction not only to ensure that the construction process The strength of each component does not exceed the standard and the structure as a whole is stable and reliable. At the same time, the additional internal force or residual stress generated in the structural components should be controlled at a lower reasonable level.
