Structural performance of steel plates

In general, plates are classified as thick when the minimum dimension to thickness ratio (b/h) is less than 10, thin b/h ranges from 10 about 100, provided that plate maximum deflection (w/h) 0.2, and membranes approaches 100 w/h ≥ 0.2. Thick develop internal stress resultants governed by three-dimensional elasticity similar of a solid body. Thin behave plane members two-dimensional elasticity. Membranes can only tensile within plate’s neutral plane. Few studies have adopted ratios between 90 110 investigate feasibility utilization such in their various available forms. The current study with aims fill gap. Steel Plates different forms intact plates, stiffened, perforated, stiffened perforated plates. They used buildings, bridges, ships, well aerospace structures. this study, investigated steel has square shape subjected uniaxial loading. edges simply supported. 200 mm wide 2 thick. case, critical buckling strength is, strength. With further loading, would experience an undesirable sudden mode failure owing instability. This at investigating performance intact, 100. A pushover finite element linear elastic analysis nonlinear large been carried out. indicated increase single, double, triple stiffener was 75.6%, 174%, 196%, respectively, compared plate. Based on obtained results, it concluded having feasible appropriate form adopted.
