| Abstract: |
Built in 1941 and strengthened for the first time is 1992, the Y-Bridge in Ho Chi Minh City (Vietnam) is set to be widened and upgraded in 2018, doubling its capacity from 2 to 4 lanes and making it in compliance with current Vietnamese Design Specifications and loading. The complex deck structure, made of concrete T- or I-shaped girders, with drop-in steel I-girder spans required various and adaptable strengthening solutions (external post-stressing, shotcrete, FRP) depending on the type and configuration of the deck. Substructure is strengthened and upgraded using reinforced shotcrete, while new piles and micropiles are cast and connected to the substructure using transverse jacking beams and external post-tensioning bars. The challenge for this project is technical, since the bridge capacity is increased for the second time, and logistical, since only a reduction of traffic during works is allowed. |
