Innovative Approaches in Prestressed Girders Bridge Design

Ahmed Rageh, PhD, PEOct 18, 2023

The midas model is for a multi-channel prestressed girders bridge 30 ft span and 24.75 ft width. The bridge is composed of 9-channel prestressed girders placed side by side. The bridge was modeled with frame elements for the girder's webs and plate elements for the girder's flange. Bridge dimensions and midas models are shown below.
