The Akashi-Kaikyo Bridge, also known as the Pearl Bridge, is the longest suspension bridge at 1,991 meters (6,532 feet) in the world. As the structure is comprised of iron latticework instead of solid stone, bridge weighs only 380 tons. In Japan, engineers faced an even greater challenge when anchoring the Akashi suspension bridge. The planners didn’t approve this consideration and so Telford goes back to the first principles of bridge design – Rope Bridge aka The Suspension Bridge. Engineers knew that iron can be made stronger if they are drawn out into a long thin string of wire. The Akashi Kaikyo Bridge Exhibition Center is the starting point of the tour. Bridge builders needed new material to build a bigger and better bridge. The Iron Bridge proves that using cast iron instead of stone, engineers can build a bridge beyond 30m. Category: Infrastructure Year of completion: 1998 Location: Hyogo, Japan Application: Heavy duty coating for steel structure Comment: The world longest* suspension bridge (* 3911m, as of 2015) Click here for details. The Akashi-Kaikyo Bridge owes its success to 7 key inventions found in 7 landmark bridges. Some projects are particularly complicated, unique in terms of design and with no information available to benchmark our production rates, crews, size of construction equipment, etc. According to Dr. Mark Ketchum, Structural Engineer. stayed bridges were analyzed.11 As to the full-scale measurements of wind fields and wind effects, other case studies include the Tsing Ma Suspension Bridge,12 Dongting Lake Bridge,13 Xihoumen Suspension Bridge,14 Hangzhou Jiubao Bridge,15 Akashi Kaikyo Bridge,16 Hakucho Bridge,17 Fred Hartman Bridge,18 and so on. The bridge was opened to traffic on 5 April 1998. The challenge is to anchor peers in the rushing water below. To dig through it and into the bedrock below, the men must work 24m underwater. The Niagara Falls Suspension Bridge was the world’s first working railway suspension bridge. 75 of these locked together to form a massive open latticework of steel. In any such bridge, the best balance of forces is achieved when the cables are set to form a particular curve. Seven construction challenges which the construction team tackled. These produce areas of varying pressure either suck the deck up or push it down. Initially, Telford considered of constructing an arch bridge from cast iron. The construction of this bridge depends on the development of several technologies. Currently, he works as a Digital Marketing Lead at Advenser, helping business with search and content marketing.
