“…It was found that the closed-form equations provide exact results for cross-sections of any number of cells of arbitrary shapes, with or without symmetry. Djelosevic et al [128] performed a research into the effect of local stress on the carrying capacity and optimum design of box girders-with rectangular cross-section. Mathematical formulation was performed to enable the definition of the local stress state by the analytical procedure.…”

“…Lerga [2] proposed a design modification in existing designs of box girders of overhead cranes and concluded a 5.5% mass reduction. Djelosevic et al [39] studied the local stress parameters of box and trapezoidal girders and concluded that trapezoidal sections have lower localized stress influence as compared to the straight sections. Capacity and span-wise optimization were performed by Abid et al [40,41] and relations and optimization factors were developed for a capacity range of 50~120 ton and a span range of 10 m ~ 32 m. Chauhan and Bhatt [42] performed finite element analysis using three different steels (EN-22, Steel-20 and Forged steel) for the hook for a 10 ton and 22 m span crane girder to study possible increase in its durability and minimum stresses were recorded for EN-22.…”

In this paper three dimensional nonlinear finite element analysis is performed for the optimization of an overhead crane box girder for capacity (50~120ton) and span (10 ~ 32 m) for safe bending stress and deflection with minimum mass and volume. A customized optimization code is developed using interpolative relations and correction factors to achieve optimized results with and without considering industrial constraints. A cutting and welding plan is developed to provide a standard operating procedure for the manufacturing of the box girder. Bill of materials, box girder design dimensions, and cutting and welding lengths are recorded with considerable time saving.

“…The end edges of the plates from which the column is formed are most often connected to the base plates, which correspond to a completely fixed support. However, the analysis of the local stress of box girders presented in study [26] shows that the conditions of a fixed supported girder have influence on the behaviour of long plates only in their immediate vicinity. The differential equation of the elastic behaviour of the plate according to [27][28] The general solution that corresponds to differential equation (1) has the following form [28]:…”

“…The first line refers to the centre line of the plate, where changes in deflection and moment have extreme values. The second line corresponds to the line of the joint of two adjacent plates along which transverse displacement is prevented and continuity of the cross section is ensured [26]. The boundary conditions in the longitudinal direction (along the x-axis) correspond with the free supported plates, because slender plates are characterized by a large number of half waves which changes sign.…”

SummaryIn this paper, we investigate global and local stability of columns with an open and a closed thin-walled cross section. The proposed model of global stability is made of two deformable elements connected with an elastic joint. Stiffness of the elastic joint represents local discontinuity of the cross section of the column caused by the loss of stability of individual plates. The model of local stability of the columns is conceptualized on the principle of continuity of individual plates of the cross section. The coefficients of local buckling are defined as geometric parameters of the column with a rectangular hollow section (RHS) and a U-shaped cross section. The dominant parameters that influence the interactive behaviour of local and global buckling are the slenderness of plates and the column as a whole. The basic function of the developed models is to identify the stability mechanism in terms of better estimation of the critical force and higher load capacity.
