      The first high-speed rail (HSR) corridor in India, built on viaducts and bridge structures, is currently under construction between Mumbai and Ahmedabad. This corridor passes through seismic Zone III, whereas future corridors ...

    • Exploring resiliency between different steel lateral systems for new construction 

      Welch, David P.; Canney, Nathan; DeBock, D. Jared (2024-04-09)
      It is known that while base level, code compliant structural designs produce buildings with a low likelihood of collapse, there is little guarantee that buildings will remain functional following moderate to severe ...
