For further study of mechanical properties of concrete-filled steel box columns (CFSBCs) with longitudinal stiffeners, axially loading tests of CFSBCs with longitudinal stiffeners was conducted to obtain their ultimate bearing capacity and failure modes. The test results were compared with those of hollow steel box columns with longitudinal stiffeners. Cross section of the test specimen was scaled from a chord member of Dongjiang Bridge. The experimental results show that failure mode of CFSBCs with longitudinal stiffeners is local buckling of steel plates, which is different from that of concrete-filled thin wall steel tube columns with longitudinal stiffeners. Although longitudinal stiffeners can prevent global buckling of steel plates, the effect is less obvious than that of concrete-filled thin wall steel tube columns. Meanwhile, three-dimensional finite element models (FEM) of the specimens were modeled using computer program ANSYS to obtain bearing capacities and load-strain curves. The FEM results coincide quite well with the test results. Further, influence of width to thickness ratio on mechanical behavior of CFSBCs was analyzed using FEM.

A plate finite element formulation is developed for the buckling analysis of steel plates symmetrically strengthened with glass fiber reinforced polymer (GFRP) plates. The solution idealizes the steel and GFRP as Kirchhoff plates while accounting for the shear-flexibility within the adhesive through a postulated zigzag displacement profile. The solution is then used to characterize the elastic buckling strength for steel plates strengthened with GFRP for corroded flanges subjected to compression, and for steel panels subjected to shear. The validity of the present model is assessed through comparisons with three-dimensional and shear deformable shell solutions. The capacity of the strengthened system is found sensitive to GFRP thickness but insensitive to the adhesive shear modulus. A design example is provided to illustrate how CAN-CSA S16-14 provisions for plate girder design can be integrated with the predictions of the present model to characterize the shear capacity of end panels strengthened with GFRP plates.

The Moment

Disturbance to stability of a member occurs with presence of any external force of different nature than that of the pre-applied load in action or through presence of any eccentric loading. These disturbances includes effects such as buckling in columns and plates which happens when action due to applied load is lesser than the moment due to disturbing agent. This paper investigates the buckling strength of steel plates subjected to loads widthwise, with varying support conditions lengthwise and an effort to trace the load deformation characteristics during post buckling stages, where the transverse strips of plates try to resist the buckling phenomena of longitudinal strips using finite element modeling tool. Hence, resulting in failure of a member at a load greater than that observed during initial buckling stages.

Reference Plate

This work searched for the optimal geometrical configuration of simply supported stiffened plates subjected to a transverse and uniformly distributed load. From a non-stiffened reference plate, different geometrical configurations of stiffened plates, with the same volume as the reference plate, were defined through the constructal design method. Thus, applying the exhaustive search technique and using the ANSYS software, the mechanical behaviors of all the suggested stiffened plates were compared to each other to find the geometrical configuration that provided the minimum deflection in the plate’s center when subjected to this loading. The optimum geometrical configuration of stiffeners is presented at the end of this work, allowing a reduction of 98.57% for the central deflection of the stiffened plate if compared to the reference plate. Furthermore, power equations were adjusted to describe the deflections for each combination of longitudinal and transverse stiffeners as a function of the ratio between the height and the thickness of the stiffeners. Finally, a unique equation for determining the central deflections of the studied stiffened plates based only on the number of longitudinal stiffeners without significantly losing accuracy has been proposed.
