Just did 12 spans graphically and it appears to be a simpler and quick method.
BTW I checked all 12 spans results and were at or within 0.01'
Assumes Road Vertical Curve greater than Span Length
• Max Midspan Girder camber value “GC”
• Max Midspan Dead load deflection value “DL”
• Max Midspan Residual Road Profile “RP”
• Grade adjustment at CL Bearing “GA”
Road Profile Curve
GC-DL-RP=GA
Road Profile Sag Curve
GC-DL+RP=GA
Further adjustments of:
Minimum haunch and cross slope to CL Girder
Bearing thickness
