Innovation and Creation of Recent Bridge Engineering under the Direction of IABSE Outstanding Structure Award

Over recent years there has been considerable development in bridge engineering. Thirty-two bridge projects have received IABSE Outstanding Structure Awards during the past two decades in recognition of the most remarkable, innovative, creative, or otherwise stimulating structures. Several creative structural forms have been created such as two twin-box girder suspension bridges, three spatial main cable suspension bridges, six multi-main-span cable-supported bridges and one cable-stayed and suspension hybrid bridge. Various innovative material combinations have been developed and used in two steel truss and PC flange composite girder bridges, one butterfly web extradosed bridge, one multiple material strength bridge and one long-life concrete cable-stayed bridge. Some remarkable functional technologies have been invented for two remarkable movable bridges, two innovative cable-stayed bridges, two extreme seismic function cable-supported bridges and two environmental coordination bridges. Many stimulating bridge projects have been awarded as Winners or Finalists including three extradosed bridges, four arch bridges, two cable-stayed bridges and four sea-crossing bridges. The innovation and creation of recent bridge engineering has been recognised by IABSE Outstanding Structure Award reflecting the creative structural forms, the innovative material combinations, the remarkable functional technologies and the stimulating bridge projects.
