Bridges Construction
Yi Sun-sin Bridge is a suspension bridge in the south coast of South Korea. The bridge is one part of The Approach Road to Yeosu Industrial Complex. It is the world's fifth longest suspension bridge in terms of its main span length of 1,545 m since it opened in 2012. The bridge connects Gwangyang with Myodo-dong, a small island that is part of Yeosu City.
‘Yi Sun-sin’ is the name of the Korean Admiral who was born in 1545 and built the world first ironclad warship called 'the Turtle ship' and defended the country against Japanese navy in the Joseon Dynasty. Some people miswrite his last name like 'Lee' instead of 'Yi' but 'Yi Sun-sin' is his official name. The bridge was designed by Yooshin corporation and was constructed by Daelim Industrial Company.
Unlike the previous suspension bridges in Korea, Daelim's engineers carried out the whole construction engineering by themselves despite its outstanding scale compared with the former ones.
The bridge was a finalist in the Outstanding Structure Award 2013.
A suspension bridge is a type of bridge in which the deck (the load-bearing portion) is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.
This type of bridge has cables suspended between towers, with vertical suspender cables that transfer the live and dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without falsework.
The suspension cables must be anchored at each end of the bridge since any load applied to the bridge is transformed into a tension in these main cables. The main cables continue beyond the pillars to deck-level supports, and further continue to connections with anchors in the ground. The roadway is supported by vertical suspender cables or rods, called hangers. In some circumstances, the towers may sit on a bluff or canyon edge where the road may proceed directly to the main span, otherwise the bridge will usually have two smaller spans, running between either pair of pillars and the highway, which may be supported by suspender cables or their own trusswork.
