架构师提供的文本描述。单一质量作为外观(性能)

Text description provided by the architects. One single mass as façade (Performance)

Costanera Lyon 2是为了否定典型的幕墙建筑类型而设计的。采用结构单一质量，具有优良的被动设计，易于加热或冷却，而不添加双层皮肤或消耗大量的能源。

Costanera Lyon 2 was designed in order to negate the typical curtain wall building typology. Using the structure as a single mass with an excellent passive design, easy to heat or cool without adding a double skin or consuming a lot of energy.

作为外观的设计过程。(证据)

Design process as facade. (Evidence)

Costanera Lyon 2被迫使用悬臂板，以便最大限度地利用给定场地的所有平方米。建议中的悬臂板在重力和地震作用下不起作用。解决方案是增加一系列周边墙，以提供扭转刚度的结构。为了让更多的视野从墙内变成了一系列的空腹梁，承载了建筑的自重，通过立面。对这座建筑进行了重新思考，并将其设计成预制构件：21根空腹梁、16块板、1根核心和14根剪刀基柱。

Costanera Lyon 2 was forced to use cantilever slabs in order to maximize all the square meters of the given site. The proposed cantilever slabs didn’t worked under gravitational and seismic forces. The solution was to add a series of perimetral walls in order to provide torsional rigidity to the structure. In order to allow more views from inside the walls became a series of Vierendeel beams that carry the dead load weight of the building trough the façade. The building was rethought and designed as an essay of prefabricated elements: 21 Vierendeel beams, 16 slabs, 1 core and 14 scissor base columns.

由于智利的地震条件，强烈建议建造原型2作为一个整体。外墙变成了两种对立观念的悖论，一种是加固的混凝土形式，实际上是一座纸牌屋；如果一个元素被移除，整个建筑就会倒塌。

Because of Chile seismic condition is highly recommended to build the prototype 2 as one piece. The façade became a paradox of two opposite ideas, one reinforced concrete form that really works as a house of cards; if one element is removed the whole building will collapse.

构造逻辑(构造)

Structural logic as façade (Tectonic)

在Costanera Lyon 2，所有的专栏都是从办公室内部释放出来的。该结构是通过堆放一系列空腹梁在立面上设计的。垂直和地震荷载工作通过一个系统的Viernedeel梁，创造和不变形的几何。一个系统，优化质量和提供适当数量的扭转刚度与固体和空隙的完美平衡，以创造舒适的内部空间。

In Costanera Lyon 2  all the columns were release from the interior of the offices. The structure was designed by stacking a series of Vierendeel beams on the façade. Vertical and seismic loads works trough a system of Viernedeel beams that created and non-deformable geometry. A system that optimize the mass and provide the right amount of torsional rigidity with a perfect balance of solid and voids to create comfortable interior spaces.
