Percy Penafiel, P.E. from Nevada Department of Transportation, will be going over the lessons and process of the Elkhorn Drop Ramp Structure. When it comes to complex geometry many engineers struggle while using grillage approach or using plate modeling. That was the issue that some engineers at Nevada DOT were facing, until Percy was able to use MIDAS Civil and MIDAS FEA to do both approaches easily. During the presentation Percy will demonstrate how he was able to model his flare bridge using the grillage approach in MIDAS Civil and cross checking it with our plate modeling meshing module FEA NX.
