【摘要】：随着经济水平的提高和建筑技术的发展，人们对于建筑内部空间效果的追求也不断提高。特别是体育场馆、剧院、会展等类型的建筑，，其主体功能需要建筑物提供大型通透的公共空间。这类建筑对结构跨度、悬挑长度的要求，迫使结构工程师选择更加轻质高强的建筑材料。上部钢结构屋盖（罩棚）与下部钢筋混凝土结构相结合的建筑方案在这类建筑中比比皆是。对于这类上下组合的建筑，传统的结构设计多采用上、下两部分独立建模、独立分析设计的方法；但是这种设计方法无法考虑两部分结构的协同工作、相互影响；从而影响方案比选的合理性，以及结构的经济性和安全性。此外，在整体建模、协同分析时，由于整体结构由两种材料组成，其整体分析时的阻尼比与单一材料结构有所不同，影响结构分析结果。本文结合天津网球中心比赛场项目的结构设计过程，分别介绍了钢结构罩棚的方案比选方法，比较了独立分析与协同分析的差异，以及整体分析结构阻尼比的确定方法，从而说明此类建筑结构进行整体建模、协同分析的必要性，并对此类建筑结构的钢结构方案比选方法、整体结构有效阻尼比确定提出一些参考性建议。
[Abstract]:With the improvement of economic level and the development of architectural technology, the pursuit of the interior space effect is also increasing. Especially in the stadium, theater, exhibition and other types of buildings, its main function needs the building to provide large and transparent public space. This kind of building requires structural span and cantilever length, forcing structural engineering. The teachers choose more lightweight and high-strength building materials. The building schemes of the upper steel structure roof (canopy) and the lower reinforced concrete structure are everywhere in this type of architecture. For this type of upper and lower combination, the traditional structural design is used more, the next two parts are built independently and the design method is independently analyzed; but this design is designed. The method can not consider the cooperative work of the two parts of the structure and influence each other, thus affecting the rationality of the scheme selection, and the economic and security of the structure. In addition, in the overall modeling and cooperative analysis, the overall structure of the overall analysis is different from the single material structure because the overall structure is composed of two materials, and the structure analysis affects the structure analysis. Result.
In this paper, based on the structural design process of the Tianjin tennis center competition field, this paper introduces the method of the scheme comparison of the steel structure canopy, compares the difference between the independent analysis and the cooperative analysis, and the determination method of the overall analysis of the damping ratio of the structure, so as to explain the necessity of the integral modeling and the synergistic analysis of this kind of building structure. Some reference suggestions are given for the comparison and selection method of the steel structure scheme of the building structure and the effective damping ratio of the whole structure.
