| 摘要： | The winning concept was a one-of-a-kind concrete network tied arch design that captured the imaginations of Angelenos, who had wanted a carbon copy of the original viaduct. Working with the Los Angeles Bureau of Engineering, under the leadership of City Engineer Gary Lee Moore, the project team successfully delivered the largest, most complex bridge project in Los Angeles history, meeting each of the project's challenging requirements with a series of engineering firsts. At night, programmable LED accent lights illuminate the underside of the arches and Y-bents, giving the viaduct its name: Ribbon of Light. Ensure greater public safety through seismic resilience. Designed to remain undamaged and operational after a seismic event with a 1,000-year return period, the viaduct sets a new precedent for seismic safety and is believed to be the world's longest, seismically isolated concrete network tied arch bridge at 3,060 feet. The viaduct is the first structure in the U.S. to be designed with multi-strand post-tensioning couplers in the prestressing system. Used to provide continuity of the 10 4.5-inch-diameter post-tensioning tendons placed in edge girders between frames, post-tensioned couplers were an efficient connection that made the post-tensioning continuous from one end of the bridge to the other. |
