The most distinguishing feature of a plate girder is the use of the transverse stiffeners that provide tension-field action increasing the postbuck-ling shear strength. "Implementation of an Energy-Based Stiffened Plate Formulation for Lateral Load Distribution Characteristics of Girder-Type Bridges. This methodology is for a single span steel girder bridge that uses only strain measurements of the steel girders beneath the bridge deck to determine the weight and accompanying characteristics of trucks traveling over the bridge. The shearing process performs only fundamental straight-line cutting but any geometrical shape with a straight line cut can usually be produced on a shear. No anchoring fixtures are used between the pedestal and the floor. By modeling the deck of a curved box girder with modified curved beam element, using normal curved beam element for modeling the bottom plate, the webs and the corner stiffeners, a spatial displacement field is constructed for the analysis of a curved box girder. material characteristics and. An elevation of the main longitudinal girders is depicted in figure 3. Metal shearing can be performed on sheet, strip, bar, plate, and even angle stock. This paper takes the dipole and girder as a specific model system, a method for studying the dynamic characteristics of the system is put forward by combining theoretical calculation with experimental testing.
