[摘要] 工程主體為純框架結(jié)構(gòu)，屋蓋采用曲線大跨度鋼網(wǎng)架結(jié)構(gòu)形式，支座處利用了減震耗能技術(shù)。根據(jù)建筑設(shè)計(jì)要求，結(jié)構(gòu)正面飛檐、屋面雙曲弧面、屋面?zhèn)壬觳糠?、背面圍護(hù)及側(cè)挑部分構(gòu)成了結(jié)構(gòu)設(shè)計(jì)的幾個(gè)難點(diǎn)。通過(guò)工程中這些既聯(lián)系又相對(duì)獨(dú)立的多個(gè)子項(xiàng)設(shè)計(jì)，只要采取正確簡(jiǎn)潔的方法，就既可滿足建筑功能的要求，又能收獲結(jié)構(gòu)的美感，是此類建筑結(jié)構(gòu)的設(shè)計(jì)方向。

Abstract: The principal part of this project is frame structure. The roof adopt the steel grid structure oflong-span curve. The techniques of absorption of vibration and consumption energy are used in the pedestal. Base on the request of architectural design, there are some difficulties, such as the structure ofpositive cornice, hyperbolic cambered roof, part of the roof extension, the back-decoration and part ofthe back extension. For these sub-items of the project which are not only the mutual relationship but also the relative independence, if using correct and compact method to satisfy the requirements of construction function, moreover to get the structural aesthetic feeling. It is the direction for this type of structural design.
