CE 583 Bridge Design


Text: No required texts

1)    AASHTO LRFD Bridge Design Specifications



Midterm around mid-May

Design moment and shear envelope data will be here



Analysis and Design Spreadsheets

MCFT by Evan Bentz of University of Toronto

Moment-Curvature Analysis for AASHTO by C. Higgins Oregon State University



Software for moving load analysis

VIDEOS Start Here 1 __ How to 1 __ How to 2 and How to 3

Here is how to get it: 1) Make a folder on your z drive called Bridge

2) Right click on the file you want to download from this page

3) Click Save target as

4) Navigate to your folder Bridge on your Z drive (or local hard drive)

5) Click Save

6) Click Close in dialog window

7) Go to back to step 2 to get other files you want (need both the truck and locations files to run)

8) Edit the locs.dat file for the locations you want

9) Double click the executable to perform the analysis

Download: Single span (with end cantilevers)

Download: Truck input file for HL93 analysis (required)

Download: Truck13 input file for random truck analysis (optional)

Download: Location to compute force effects at interior beam locations (required)

Download the Headers Information for Output files (optional but this helps)
