大跨度空间钢结构施工与监测

Construction and Monitoring of Steel Structures in Large-Span Spaces

依托于风荷载对大跨度空间钢结构的影响理论以及大跨度空间钢结构施工阶段受风力振动的效应进行案例分析。在案例分析过程中基于BIM软件掌握大跨度空间钢结构的杆件数量、安装节点数量,并利用有限元计算分析软件开展施工模拟,依托于有限元软件的计算分析结果验证风力减振技术措施的成效并监测节点位移,从而为大跨度空间钢结构的施工与监测提供技术参考。

Relying on the theory of the influence of wind load on long-span space steel structure and the effect of wind vibration during the construction stage of long-span space steel structure,a case study is carried out.In the case analysis process,based on the BIM software,the number of members and installed nodes of the long-span space steel structure are mastered,and the construction simulation is carried out by using the finite element calculation and analysis software,and the effectiveness of wind vibration reduction technical measures and the node displacement are monitored based on the calculation and analysis results of the finite element software,so as to provide a little technical reference for the construction and monitoring of the long-span space steel structure.
