The Bridge of Aspiration
心願橋
'The Bridge of Aspiration, Covent Garden, London'
‘心願橋,柯芬園,倫敦’
A square cross-section rotates through 90 degrees from one end to the other, creating a
fusilli-like twisted form. The two end portals are not directly opposite each other, and as
can be seen from below, the bridge's geometry provides a rational way of dealing with
the requirements of a skewed crossing.
從起始端到末端是一個扭曲成90度的長方體,看起就像個螺旋體一樣。兩端的
連結口是不對稱的。從橋的下方往上看,我們可以看到橋外觀的幾何形狀形成
了一個交叉交錯的景象。
Structurally, the primary element is an aluminium box girder, which helps reduce the weight
and hence the loads on the supporting buildings. The girder twists in such a way that it is
shallowest at its ends (rectangular in cross-section), and deepest at midspan (triangular), as
befits the bending moment diagram.
在結構上,使用的材料為鋁,有助於減輕橋樑的重量,以減輕兩端建築物負荷
的重量。橋的外觀使用扭曲的方式主要是因為橋樑兩端連接建築物的地方使用
方形,在中間部分則變化成三角形,這樣的彎矩正符合此橋樑的力學構造。
The girder supports a series of square frames, with glazing between them, each of which
is rotated approximately 4 degrees relative to its neighbour.
橋樑的鋁被設計成方形,每個方形之間的夾層材料則是使用玻璃,其中每個夾
層之間的間隔大約是被旋轉成4度。
