Load Rating and Rehabilitation of the New River Gorge Bridge

Purpose of the Webinar
Load Rating and Rehabilitation of the New River Gorge Bridge

This webinar discussed the methods used for the analysis, conducted using a three dimensional model in Midas Civil software. The model incorporated wind and temperature loading, along with nine different rating trucks. The results of the analysis were used to calculate rating factors for over 4500 members and over 1800 gusset plates and connections. The rehabilitation plans which were then in development were also discussed. These plans include steel repairs to the superstructure and substructure and bearing rehabilitation.
