“…There are many previous studies that related to this work, Abeer, et al (2013) [6] predicted a new analytical method to surmise the behavior and the torsional capacity of the reinforced concrete multi-cell box girder with CFRP sheets strengthening, the study modified the softened truss model with the proposed method. Ezeokpube, et al (2015) [7] presented a numerical and experimental modelling for the static response of simply supported thin-walled reinforced concrete box girder bridges. The study included six reinforced concrete box girder bridges with the same dimensions of (3220mm) length, (322mm) height and (500mm) bottom flange width with different top flange width, this work was carried out in order to verify the validity of the software for the finite element, and also to study the effect on the flange width on the response of the box girder bridge.…”

The aim of this research is to study the effect of using corrugated steel plate strengthening on the structural behaviour of reinforced concrete box girder by using corrugated steel plates with vertical and horizontal corrugation and studying the effect of the shape of cells by using rectangular and circular shape with the same web width and strengthening the circular cell with smooth plate. Five simply supported reinforced concrete box girders are casted by using Self-compacting concrete and experimentally tested under four-point load. The box girder specimens are divided into two groups according to the steel strengthening and the shape of cells. The experimental results showed that in the first group, the using of the vertical and horizontal corrugated steel plates strengthening increased the ultimate load by (7.14% and 11.03%) respectively compared with the control box girder, and decreased the crack width, the results also showed that in the second group, the using of circular cell and circular strengthened cell increased the ultimate load by (17.85% and 29.22%) respectively compared with the control box girder with rectangular cell and decreased the crack width. All the box girders in the first and second group failed with diagonal shear.

“…With recent developments, thin-walled box-section structures have been extensively used in engineering components thanks to their impressive performance, such as a high stiffness-to-weight ratio and high torsional and bending rigidities [1][2][3]. For example, box-section girders [4][5][6] and columns [7] are familiar applications of civil engineering structures.…”

Structural Performance of Thin-Walled Twisted Box-Section Structure

The light weight and high strength-to-mass ratio of thin-walled boxed sections have incited interest in their widespread use in the construction of domes. However, the installation of these sections in forming the dome geometry has induced initial twists and curving features, to which their mechanical response has rarely been explored. Therefore, the structural performance of a structure with thin-walled twisted box sections is numerically studied in this paper, employing ANSYS, the verification of which is carried out through a comparison with experimental results. Additional components examined include the longitudinal stiffening rib, diaphragm, and web. The effects of variations in the thicknesses of these member plates on the mechanical behaviors are investigated. In general, the ultimate capacity of the structure is improved by increasing the thickness of the longitudinal stiffening rib, diaphragm, and web, but the strengthening effect of the stiffener is limited by a certain thickness enhancement. The common failure mode of the initial model is found to be an overall elastic-plastic buckling. A reduction in the thickness of the stiffener or web creates a curving deformation zone in the lower arch at the ultimate capacity, whereas the diaphragm thickness has little effect on the failure mode of the model.
