SIDE ELEVATION
• Live load = 40 psf
• Decking = 5 psf
• Beams = 5 plf
. Girder = 20 plf
• Concrete density = 150 pcf
Soil bearing capacity = 4,000 psf
Footing height (thickness) = 10 in
After the initial calculation, we determined the following information:
The reaction force for a typical interior beam (ledger beam side) = 1,189.3 lbs
• The reaction force for a typical interior beam (girder side) = 2,140.7 lbs
• The reaction force for a typical exterior beam (ledger beam side) = 610.7 lbs
• The reaction force for a typical exterior beam (girder side) = 1,099.3 lbs
Please round to the nearest one-tenth (i.e., 0.1).
