技术领域 technical field
本实用新型涉及大型钢结构建筑，具体是一种大型钢结构建筑温度应力释放结构。 The utility model relates to a large-scale steel structure building, in particular to a large-scale steel structure building temperature stress release structure.
背景技术 Background technique
由于自身的优良性能，钢结构已广泛用于厂房、库房、体育馆、展览馆、机场机库等工程，但对于大跨度、多跨数、高立面大型钢结构体系，目前的设计规范发展滞后。据《钢结构设计规范》（GB 50017-2003）8.1.5单层房屋和露天结构的温度区段长度（伸缩缝的间距）对采暖房屋和非采暖地区房屋纵向温度区段不超过220m，横行温度区段不超过120m（柱顶刚结）和140m（柱顶铰结），否则要考虑温度应力温度变形的影响。但是设置变形缝也相应的出现一些不利因素（如不满足工艺要求、管线布置复杂、立面不美观、排水系统复杂等），这就极大的限制了结构的尺寸。而大型和超大型钢结构体系是未来工业、民用建筑发展的一个重要方向，对此类结构在温度变化情况下的研究也就显得尤为重要。 Due to its excellent performance, steel structures have been widely used in factories, warehouses, gymnasiums, exhibition halls, airport hangars and other projects. However, for large-span, multi-span, and high-facade large-scale steel structure systems, the development of current design specifications lags behind. . According to "Code for Design of Steel Structures" (GB 50017-2003) 8.1.5, the temperature section length (distance of expansion joints) of single-storey houses and open-air structures shall not exceed 220m for heating houses and houses in non-heating areas. The temperature section shall not exceed 120m (column top rigid junction) and 140m (column top hinged connection), otherwise the influence of temperature stress and temperature deformation shall be considered. However, the installation of deformation joints also has some disadvantages (such as not meeting the process requirements, complex pipeline layout, unsightly facade, complex drainage system, etc.), which greatly limits the size of the structure. Large-scale and super-large steel structure systems are an important direction for the development of industrial and civil buildings in the future, and the research on such structures under temperature changes is particularly important.
