Question
Use LRFD and determine the flange and web dimensions for a plate girder of the type shown in Figure for the following conditions: ●● Span length =50 ft. ●● Girder is simply supported with lateral bracing at 12 ft-6 in. intervals. ●● Superimposed service dead load = 0.5 kips/ft (does not include the girder weight). ●● Concentrated service live load =130 kips applied at midspan. ●● Steel is A572 Grade 50. Select the flange and web dimensions so that intermediate stiffeners are not required. Assume that a bearing stiffener will be used at the concentrated load.
