波纹拱型屋盖结构具有自重轻、室内空间大、造型优美、施工周期短、防水性能好、集受力与维护功能于一身等诸多优点.我国于1992年通过引进美国设备而引进了该种结构体系,并得到了广泛应用.但由于拱型波纹屋盖的受力性能、破坏机理和破坏模态极为复杂,没有被工程技术人员完全了解,也没有形成统一的计算模型、计算方法和分析方法.虽然有了《金属拱型波纹屋盖结构技术规程》和已经通过国家验收的计算软件,但规程没有提供给设计者使用的更加详细的计算图表,在一定程度上阻碍了规程的实际应用,尤其近几年出现的一些工程事故,严重阻碍了这种结构的健康发展.本文通过总结拱型波纹屋盖结构在国内外的研究发展现状、实际应用现状以及存在的问题,提出了该结构在今后理论研究和实际应用的建议.
Corrugated arched roof structure with light weight, large interior space, sleek, short construction period, waterproof performance is good, set the force and maintenance functions in one of the many advantages of our country in 1992 through the introduction of the United States and the introduction of the equipment Structural system and has been widely used.But due to the stress performance, failure mechanism and failure mode of arched corrugated roof is extremely complicated, it has not been fully understood by engineering technicians, nor formed a unified calculation model, calculation method and analysis Method.While there is “the technical regulation of metal arched corrugated roof structure” and the calculation software that has passed the national acceptance, the procedure does not provide more detailed calculation charts for designers to use, which hinders the practical application of the procedure to a certain extent In particular, some engineering accidents that occurred in recent years have seriously hampered the healthy development of this structure.This paper presents the status quo of research and development at home and abroad of arched corrugated roof structure, the actual application and the existing problems, In the future theoretical research and practical application of the proposal.
