跃于湖面的钢筋芦苇 Pedestrian Bridge / Miró Rivera Architects

Miró Rivera Architects：這座人行天橋位於奧斯汀湖的植被茂密處，它連接了住宅主體和新建的賓館。這座橋的設計靈感來自覆蓋湖岸的蘆葦和其他原生植被，是一座輕便、免維護的結構，與濕地環境融為一體。鋼筋/蘆葦在橋墩處相互纏繞，“生長”在橋上，將橋偽裝起來，使之成為一種共生的、幾乎不可見的建築。
Miró Rivera Architects：Located on a densely vegetated site in Lake Austin, the Pedestrian Bridge connects the main house on the property with a newly constructed guest house. With a design inspired by the reeds and other native vegetation that cover the shores of the lake, the bridge is a light and maintenance-free structure that is well-integrated within its wetland setting. The bars/ reeds intertwine at the abutments and “grow” over the bridge, camouflaging it and transforming the bridge into a symbiotic, almost invisible link.
這座拱橋總跨度為100英尺，主跨度80英尺。它由五個嵌套的直徑為5英寸的管道組成，這些管道在主跨度的發力點和橋頭的橋台之間優雅地分開。
The arch structure spans 100 feet with a main span of 80 feet. It is composed of five nested five-inch diameter pipes that diverge grace- fully between the spring-point of the main span and the abutment at the beginning of the bridge.
這些管道支撐著1⁄2的柵欄，通過簡易的水平垂直彎曲組合，作為橋樑裝飾和護欄。鋼筋的不規則長度和緊密間距呼應現場的天然蘆葦，當透過蘆葦的視覺面紗觀看時，上層結構的薄輪廓會變得更薄。
The pipes support 1⁄2 diameter bars that act as both decking and guardrail via a simple field bend from horizontal to vertical. The irregu- lar length and close spacing of the bars recall the native reeds of the site, and the thin profile of the superstructure is made thinner when viewed through the visual veil of the reeds.
1×1水平管焊接在垂直桿上，橋樑扶手則由用鋼絲環固定在水平管上的繩子構成。再用天然石板垂直鋪設，在橋墩處形成坡道。深斜接縫重現呼應了甲板和欄杆鋼筋的節奏。為了進一步將這座橋與自然環境融為一體，鋼結構還未完工就暴露在外任其侵蝕，就像繩索扶手和石頭坡道一樣。
The handrail consists of a rope secured with steel wire rings to a 1×1 horizontal tube welded to the vertical bars. Native stone slabs are lay- ered vertically to create the ramps at the abutments. Deep raked joints recreate the rhythm of the steel bars of the deck and railings. To further incorporate the bridge with its natural setting, the steel is left unfinished to weather, just like the rope handrail and the stone ramps.
