THE BUCKLING OF A PLATE GIRDER WEB UNDER PURE BENDING WHEN REINFORCED BY A SINGLE LONGITUDINAL STIFFENER.

The nonlinear stiffness equations that predict local and post-local buckling of plates and plate assemblies are given. These equations are validated by accurate predictions of independent test results. The elastic local buckling of longitudinally stiffened web plates in combined bending and compression is considered. Graphs which may be used to predict the optimum position of a stiffener are presented. The relationship between the area and second moment of area of a stiffener of finite dimensions that optimizes the local buckling coefficient is given for various eccentricities of end load. The post-local buckling of a longitudinally stiffened plate in uniform compression and pure bending is also considered. It is shown that the provision of a longitudinal stiffener, of proportions to enforce a node at the plate–stiffener junction, enhances significantly the postbuckling response of the plate with regard to the serviceability limit state, particularly for the case of pure bending. Key words: bending, compression, finite strips, local buckling, plates, postbuckling, stiffeners, webs.

Due to the high corrosion resistance, the use of stainless steel is increased in a wide range of environment in the last two decades. The behaviour of stainless steel is different from that of carbon steel, especially in a stress-strain relationship. Stainless steel has a rounded stress-strain curve, whereas carbon steel exhibits a sharp yield point in the stress-strain curve. Stainless steel has better strain hardening capacity and possesses high ductility. Stiffeners are generally utilised in plate girder for increasing the load-carrying capacity by providing better resistance against buckling of web panels. The existing study related to austenitic stainless steel plate girder studied the effect of longitudinal stiffener placed at the centre of the web panel alone. Present work uses to optimise position of longitudinal stiffener in stainless steel plate girder subjected to combined bending and shear. The behaviour is analysed by using finite element software ABAQUS. The optimum location for longitudinal stiffener in long-span stainless steel plate girder under combined bending and shear was identified and compared the results with the standard design codes.

Abstract A mathematical analysis of radial tire cornering was performed to predict tire deflections and belt-edge separation strains. The model includes the effects of pure bending, transverse shear bending, lateral restraint of the carcass on the belt, and shear displacements between belt and carcass. It also provides a description of the key mechanisms that act during cornering. The inputs include belt and carcass cord properties, cord angle, pressure, rubber properties, and cornering force. Outputs include cornering deflections and interlaminar shear strains. Key relations found between tire parameters and responses were the optimum angle for minimum cornering deflections and its dependence on cord modulus, and the effect of cord angle and modulus on interlaminar shear strains.
