摘要: 上海某过江隧道通风塔高 180m，同时具有隧道通风、旅游观光、餐饮商务等多种功能和业态，是一种新型的建筑形式。 该通风塔平面接近正圆形，中央核心筒接近椭圆形，采用混凝土筒体+悬挑楼板+幕墙网壳结构体系，幕墙采用悬挂式滑动柱面网壳结构。 详细阐述了该通风塔的结构设计思路、设计方法、设计难点和解决方案；比较了通风塔主体结构风洞试验和规范风荷载作用下的楼层剪力、弯矩的差异，并分析了前者远大于后者的原因；给出了 YJK、ETABS 和 SAP2000 等多种软件分析得到的主体和幕墙结构的主要计算结果，以及采用 ABAQUS 软件进行罕遇地震动力弹塑性分析的结果。 结果表明，该通风塔结构在各种工况下均足够安全。 最后，总结了设计过程中的经验并进行了几点思考，提出了对同类型建筑的结构设计建议。

Abstract: A 180m height tower in Shanghai services mainly as ventilation for the underground tunnel system， andprovides additional functions such as tourism， and catering business， which makes it be a new type of architectural form.The section plane of the ventilation tower is close to circular， and its core tube section plane is close to ellipse. Concretecore tube + cantilever floors + suspended latticed shell of curtain wall structural systems are adopted， and the curtain wall iscomposed of several suspended sliding cylindrical shell structures. The structural design ideas， design methods， designdifficulties and solutions of the ventilation tower were elaborated in detail. The difference between the story shear force andbending moment under the wind load form from wind tunnel experiment and from the code was compared， and the reasonswhy the former is far greater than the latter was analyzed. The main calculation results of the main body and curtain wallstructure obtained by the analysis of various software such as YJK， ETABS and SAP2000， as well as the results of thedynamic elastoplastic analysis of rare earthquakes using ABAQUS software were given. The results show that the ventilationtower structure is sufficiently safe under various working conditions. Finally， the experience in the design process wassummarized and some thoughts were made， and the structural design suggestions for the same type of buildings were putforward.
