两座标志性塔楼，一种创新的结构方案

总部位于芝加哥的STLarchitects公布了他们为前芝加哥尖顶场址设计的方案。竞赛要求设计两座塔楼：一座是公寓综合体和另一座严格为公寓使用。他们的设计侧重于“芝加哥的建筑特色和基本美德......因此具有标志性，创新性和灵活性。

Chicago-based STLarchitects revealed their design for the former Chicago Spire site. The competition brief called for two towers: one supporting a mixture of apartments and condominiums and the other strictly for condominium use. Their design focused on "Chicago’s architectural character and essential virtues... thus iconic, innovative, and flexible.

这个位于芝加哥河和密歇根湖口之间的场地将设有两个向顶部逐渐缩小的细长塔楼。分离的塔楼将被视为城市景观，同时被确定为一个统一的项目，为天际线增添壮丽景色。

The site, located between the Chicago River and the Ogden Slip at the mouth of Lake Michigan, would feature two slim towers that taper towards the top. The separated towers would frame views of the city while also being identified as one, unified project contributing to the skyline.

该建筑的规模取决于场地的限定，要求用一种创新的结构工程解决方案，利用减震器技术的优势消除调谐体量减幅的需求。这不仅有助于降低塔架的成本，还可以提高稳定性。

The size of the building relative to the constraints of the site called for an innovative structural engineering solution that "takes advantage of viscous damper technology eliminating the need for tuned mass damping." Not only does this help reduce costs of the towers, but it also gives a greater structural stability which returns valuable real estate space at the top of the programs.

STLarchitects也考虑了底板的几何形态，以适应每个住宅楼层的各种单元类型。立面也适用于此，并允许窗户的不同图案和表现形式，包括框架式，落地窗，甚至是两者的组合。

STLarchitects also considered the geometry of the floor plates to allow for a variety of unit typologies within each residential level. The facade is adaptable to this as well and enables different patterns and expressions of windows including framed, full glass window walls, or even a combination of both.
