大跨度空间钢结构支吊架的施工抗震技术研究

为保证大跨度空间钢结构支吊架抗震施工技术在城市建设与规划过程中发挥积极效用,需对其进行研究。提出一种基于BIM技术的大跨度空间钢结构支吊架的抗震施工方法,该方法介绍大跨度空间钢结构支吊架的组成及其抗震施工布置要求、施工依据和施工工序,并阐述BIM技术在钢结构支吊架结构抗震施工中的具体应用,包括施工流程和施工原则。通过模拟工程实例分析证明,采用BIM技术进行抗震施工后的大跨度空间钢结构支吊架试件的承载力和抗侧刚度均有明显提升,在地震发生初期承担了建筑结构的大部分地震内力,具有较好的抗震性能。

Seismic Construction Technology for Long-spanSpace Steel Structure Hangars

To ensure the active application of seismic construction technology of long-span space steel structure hangars in urban construction and planning, it is necessary to study the seismic technology of these hangars. This paper proposes a seismic construction method for such hangers based on building information modeling (BIM) technology. This method introduces composition, seismic construction requirements, construction basis, and the construction procedure of long-span space steel structure hangars, and describes the specific application of BIM technology in seismic construction of these structures, including construction process and construction principle. A simulation engineering example analysis proved that after seismic construction using BIM technology, the bearing capacity and lateral stiffness of long-span space steel structure hangars were clearly improved, and the structure bore most of the seismic internal forces of the building structure in the early stage of an earthquake.
