摘要
为了解既有大跨度钢结构使用中的风险情况,选择3个典型,网架结构、索膜结构、预应力管桁架挑篷结构安全检测及重点关注内容。给出既有大跨度钢结构检测维护方面的一些需要重点注意的问题,同时给出大跨度钢结构日常维护建议,为类似项目提供参考。
In order to understand the risks in the use of existing large-span steel structures,three typical are selected,through the discussion of the safety inspection of a grid structure,a cable membrane structure,and a prestressed pipe truss canopy structure,suggestions on the inspection and maintenance of the existing large-span steel structure from the aspects of technology are given.The suggestions on daily maintenance of long-span steel structures are put forward,providing the reference to similar projects.
