| 摘要： | Engineering consulting group COWI has successfully completed hanger installation of the first of 10 spans of the new 6th Street Viaduct in Los Angeles. The original viaduct, built in 1932, was composed of three independent structures: the reinforced concrete west segment; the central steel arch segment over the river; and the reinforced concrete east segment. It was demolished in 2016 to make way for a new bridge. Like the old viaduct, the new one spans US Freeway 101, several rail roads and the Los Angeles River to provide a vital connection between Boyle Heights and downtown LA. The 932m-long and 30.5m-wide bridge -designed by Michael Maltzan, Architect and structural engineer at HNTB - includes 10 network arch spans, with a total of 388 hangers supporting the bridge deck. Once complete, the US$588 million bridge project will feature the art deco style similar to the original structure. Appointed as the erection engineer on the project, COWI worked closely with Skanska Stacy and Witbeck (SSW) to develop a constructable erection sequence. This includes step-by-step camber and stress analyses as well as hanger installation and stressing procedure of the bridge. |
