MIDAS Expert Session Effects of Long term deformations on Geometrically Complex Bridges
In this expert session, we look at how NVDOT uses shrinkage and creep deformations, which were calculated to demonstrate how these deformations can affect other bridge components in cases where the geometry of the bridge is complex. This work was based on an existing bridge located in Las Vegas. The bridge was built in 1995. Over the years, the bridge was inspected noticing large deformations at the expansion joints along with strip seal failures, cracks in wingwalls and shear keys. These repairs generated additional maintenance cost that could be avoided using sophisticated analysis during the design phase. It should be noted that software capabilities as today were not available at that time. MIDAS Civil was used to model the bridge and results were compared to simplify methods.
