Performance-based structural fire engineering of tunnels
Utgivningsinformation: Borås : RISE Research Institutes of Sweden, 2020Beskrivning: s. 677-679Ämnen: Onlineresurser: I: Proceedings from the Ninth International Symposium on Tunnel Safety and Security, Munich, Germany, March 11-13, 2020Abstrakt: This case study focuses on a tunnel that is constructed as a 740 foot bridge deck spanning over a highway corridor. The bridge deck also provides support for park landscaping, multi-use recreational paths, surface streets, HOV lane connections and light rail transit lines located above the tunnel. The tunnel consists of a reinforced concrete deck that is supported by high-strength, precast-prestressed concrete wide flange girders. The girders sit atop cast-in-place pier walls on spread footings. Unlike traditional mined, bored or cut-and-cover designs, this tunnel/bridge configuration presents inherent challenges in a fire scenario.Inga fysiska exemplar för denna post
