CE 315 Moving load/project #2 Due date: 12/06/2020

The report of the project#2 must be submitted online as a single PDF file. The results of simulation using 3D demo RISA should be included. You can use screenshot option of windows to report the results. For each moving load/truck assume two-way route and report envelope for shear and moment for 42 cases (7 trucks moving on 6 bridges). In addition, report the maximum negative and positive moments and maximum shear for each structure (complete tables 2-4).

Moving load scenarios/trucks

Seven trucks are considered in this project. The load and spacing for the truck axles are given Table 1:
