Experiment on Box Type Girders
Transactions of the Japan Society of Mechanical Engineers, 1958 For the purpose of researching the strength and the rigidity etc. of box type girders used for overhead travelling cranes, full-sized model experiments were conducted. Two model girders were used. The top deck and two web plates of one model (girder 2) were reinforced by longitudinal stiffners, while those of the other (girder 1) were not.
