  • Because the stiffening girders are constructed after the installation of hangers for typical suspension bridge, no additional tensioning to hangers in construction is necessary for this bridge type in which main cable is earth-anchored. However, for self-anchored suspension bridge, hangers are installed after temporarily supporting stiffening girders constructed in previous stage. Therefore, initial tension is required on installing hangers. Tension of hangers varies as the construction proceeds. Hence, it is necessary to determine the most efficient method of installing hangers among several methods. This study presents finite element procedures and the algorithms of construction stage analysis to simulate construction processes. Geometric nonlinear analysis scheme is also included. The most effective method regarding the installation of hangers is presented through the examples of actual bridge model.

  • The Korea Land Corporation have planned Chongna site in Incheon as a great complex town including residence, financial center, resort, shopping mall, tour and sport. One of the large estate(17,800,000$m^2$) is under construction. Cheongna site is divided into six zoning parts, according to the meaning of 6 jewels(crystal, sapphire, ruby, emerald, jade, pearl, diamond). KLC required to me 6 pedestrian with various special forms and structural system. I will introduce a various pedestrians. There are not only 4 stayed and suspended bridges, but also a truss and arch bridges.
