Critical buckling of longitudinally stiffened webs subjected to compressive edge loads

Linear buckling analysis of unstiffened plates subjected to both patch load and bending moment

“…(8a) and (8b) with some percent differences.If h/a = 1.0 and l o /a = 1.0, then k = 3.2048. This value is in agreement with the results of experimental and numerical tests collected inGraciano and Lagerqvist (2002) [8].…”

A generalized analytical approach to the buckling of simply-supported rectangular plates under arbitrary loads

“…The validity of the present analytical approach was verified extensively by numerical runs based on the finite-element (FE) Table 2 Comparison of buckling coefficients presently computed FINEL and those from [16] using ABAQUS for square plates (φ = 1) under the loading conditions shown in Fig. 10 method with sufficiently refined meshes using the program FINEL [23].…”

“…Of course, one can solve such problems by recourse to numerical techniques such as the finite-element (FE) method. Indeed, previous studies using FE packages (ANSYS or ABAQUS) have addressed some such problems (though not fully) [15][16][17]. Analytical techniques, however, can be used as benchmarks and are also better suited for performing parametric studies which are often useful for the understanding of a problem.…”

Elastic web bend-buckling analysis of longitudinally stiffened I-section girders

“…More recent numerical investigations by Frank and Helwig (1995), Azhari and Bradford (1993), Alinia and Moosavi (2008), and Graciano and Lagerqvist (2003) have used numerical approaches to develop approximate formulae for buckling coefficients. Frank and Helwig (1995) developed an expression associated with buckling coefficients for singly symmetric girder webs with and without a single longitudinal stiffener using the results of a finite element analysis.…”

“…Alinia and Moosavi (2008) investigated the optimum location and dimensions of longitudinal stiffeners in web plates under in-plane bending by utilizing the finite element method in which the boundary conditions along the transverse stiffeners and web-flange juncture were assumed to be simply supported. Using the finite element method, Graciano and Lagerqvist (2003) proposed buckling coefficients for longitudinally stiffened plate girders subjected to partial edge loading or concentrated loads. The plate girders were assumed to be simply supported along the transverse stiffeners and web-flange connections.…”
