Plate Girder Section

Calculates noncomposite and composite (for modular ratios n and 3n) section properties for steel I-girders with concrete deck. Calculates cumulative stresses at critical locations for loads applied to noncomposite and composite sections. Detailed calculations for determination of flexural and shear capacity according to AASHTO LRFD, 3rd Edition, 2004. Calculates plastic and yield moments. English units.
