Bridge+Project

** [] ** ** the ** Henderson Wave Bridge ** script ** **Bridges** are structures built over a river, railroad track, road, or some other obstacle. They allow people or vehicles to make crossing areas easier in travel. There are three types of bridges: beam, suspension and arch bridges. **A** **beam bridge** is a rigid horizontal structure that is resting on two piers, one at each end. The weight of the bridge and any traffic on it is directly supported by the piers. The weight is traveling directly downward. **The Suspension Bridge** is one where cables (or ropes or chainsand) suspended the deck. Modern suspension bridges have two tall towers through which the cables are strung. Thus, the towers are supporting the majority of the weigh. And an **arch bridge** is a semicircular structure with abutments on each end. The design of the arch, the semicircle, naturally diverts the weight from the bridge deck to the abutments. **Henderson Wave Bridge (2008)** this pedestrian bridge is one of the famous bridges of the world is located in Singapore, and its part of Southern Ridges, a 9 km set of hill parks connecting the two hills of Mount Faber and Telok Blangah Hill The Henderson Wave Bridge isbasically categorized as a **beam bridge**, but with a twist. The primary structure of the bridge features is a sequence of steel arches and catenaries joined across, and resting upon, reinforced concrete pylons. The height of those pylons is 38m, and this is the Singapore's highest pedestrian bridge. These pylons sit between waves as it were, at the point where the surface form itself intersects and tapers down to a single beam **The Structure** of the bridge has a unique wave-form made up of seven undulating curved steel -ribs- that alternately rise over and under its deck. The curved -ribs- form alcoves that function as shelters with seats within. The entire deck is being supported on a steel sub-frame with vibration dampeners, the coordination of steel and timber became a challenging task It has seven spans, six of typical size (3.5 meters high, 24 meters long), and a larger one (6 meters high, 57 meters long). The upside spans unfold above deck level and house temporary activities, such as seating, lounging and sight-seeing. The remaining spans unfold below deck level and are not accessible, there are just for simply ensuring the continuity of the structure The bridge has been constructed on various **materials**. The surface-form of Henderson Waves is made of steel and timber. Steel is needed for structural purposes, whereas timber celebrates the beauty of natural forms. Slats of yellow balau wood, an all-weather timber found in South-East Asia, are used in the decking. Look out for carvings on the slats marking the height you are at on various points along the bridge. The lighting **Technology** used on the wave-forms will be lit with attractive LED light from 7pm to 2am daily, giving the bridge an illuminative glow The pedestrian bridge Henderson Waves was commissioned by the Urban Redevelopment Autority (URA) of Singapore following an open international competition The commission was awarded to IJP Corporation and RSP Architects, Planners and Engineers in 2004, with concept and scheme design engineering by Adams Kara Taylor Consulting Civil and Structural Engineers The **Advantages** of The bridge are that allows people to have an incredible view not only over the Park, but also over the entire city of Singapore, and it promotes to experience nature in very direct way. The bridge also represents a point of interest for people around the world for being such a piece of art The principal **disadvantage** of the bridge came with its own construction that generates a distortion of the natural habitat of the parks in which this bridge was inserted. Besides this, the bridge will only bring a positive economic impact for the community of Singapore
