The theory of the V-Load method for curved I-girder bridges (Figure 2.33)
is based on the statics of a curved flange carrying an axial stress or force.
This then results in a radial distribution force on the flange, and this
radial force is converted to a shear force across the diaphragms. Thus, it is
called V-Load method . The M/R method (Figure 2.34) establishes three
equilibrium equations first. These two methods are approximate and were
