【摘要】：隨著經(jīng)濟(jì)水平的提高和建筑技術(shù)的發(fā)展，人們對(duì)于建筑內(nèi)部空間效果的追求也不斷提高。特別是體育場(chǎng)館、劇院、會(huì)展等類型的建筑，，其主體功能需要建筑物提供大型通透的公共空間。這類建筑對(duì)結(jié)構(gòu)跨度、懸挑長(zhǎng)度的要求，迫使結(jié)構(gòu)工程師選擇更加輕質(zhì)高強(qiáng)的建筑材料。上部鋼結(jié)構(gòu)屋蓋（罩棚）與下部鋼筋混凝土結(jié)構(gòu)相結(jié)合的建筑方案在這類建筑中比比皆是。對(duì)于這類上下組合的建筑，傳統(tǒng)的結(jié)構(gòu)設(shè)計(jì)多采用上、下兩部分獨(dú)立建模、獨(dú)立分析設(shè)計(jì)的方法；但是這種設(shè)計(jì)方法無(wú)法考慮兩部分結(jié)構(gòu)的協(xié)同工作、相互影響；從而影響方案比選的合理性，以及結(jié)構(gòu)的經(jīng)濟(jì)性和安全性。此外，在整體建模、協(xié)同分析時(shí)，由于整體結(jié)構(gòu)由兩種材料組成，其整體分析時(shí)的阻尼比與單一材料結(jié)構(gòu)有所不同，影響結(jié)構(gòu)分析結(jié)果。 本文結(jié)合天津網(wǎng)球中心比賽場(chǎng)項(xiàng)目的結(jié)構(gòu)設(shè)計(jì)過(guò)程，分別介紹了鋼結(jié)構(gòu)罩棚的方案比選方法，比較了獨(dú)立分析與協(xié)同分析的差異，以及整體分析結(jié)構(gòu)阻尼比的確定方法，從而說(shuō)明此類建筑結(jié)構(gòu)進(jìn)行整體建模、協(xié)同分析的必要性，并對(duì)此類建筑結(jié)構(gòu)的鋼結(jié)構(gòu)方案比選方法、整體結(jié)構(gòu)有效阻尼比確定提出一些參考性建議。
[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.
