Chapter 10, Problem 10.7.4P
A plate girder must be designed for the conditions shown in Figure P10.7-4. The given loads are factored, and the uniformly distributed load includes a conservative estimate of the girder weight. Lateral support is provided at the ands and at the load points. Use LRFD for that following:
a. Select the, flange and web dimensions so that intermediate stiffeners will he required. Use
b. Determine the locations of the intermediate stiffeners, but do not proportion them.
