Strength of Steel Box-Girder Bridges
Journal of the Structural Division, 1975The research on steel box girders in the United Kingdom which followed the recent bridge disasters is reviewed. The feature special to box girders rather than plate girders is the wider use of thin stiffened plate in the former. Because of this many of the design procedures developed for plate girders are not directly applicable to box girders.

Strength and Efficiency of Wood Box Columns
Journal of Structural Engineering, 1992This paper presents a rational procedure for determining the strength of wood box columns. The theoretical development takes into account the effects of interlayer slip that is characteristic of layered systems with nonrigid connections. One hundred and fifty box columns are fabricated and tested. Good agreement is observed between experimental results

Residual Longitudinal Strength of Damaged Box Girder Structures
Volume 11A: Honoring Symposium for Professor Carlos Guedes Soares on Marine Technology and Ocean Engineering, 2018A series of collapse tests were performed on box girder models to evaluate the effect of collision damage on the residual longitudinal strength of the hull girder. The experiments were carried out under pure bending moment using, so-called 4-point bending test method, the load, deflection and strain were measured.

Steel Box-Girder Bridges—Ultimate Strength Considerations
Journal of the Structural Division, 1974A summary of recent box-girder failures, a discussion of the design problems associated with box-girder bridges, and a review of the basis for current American design specifications are presented. The applicability of existing information to the formulation of an ultimate strength approach to box-girder design is considered.

Ultimate Strength of Box Girders With Incline Cracks
Volume 3: Structures, Safety and Reliability, 2015The aim of the present study is to investigate the residual ultimate strength characteristics of box girders with variable inclination cracks under torsional loading. A series of finite element models are established by changing the crack length and crack angle using a commercial FEA program, ABAQUS. The cracks are located at the center and torques are

Strength of Thin‐Walled Square Steel Box Columns
Journal of Structural Engineering, 1987The present study is concerned with the strength of thin-walled steel box columns of square cross section that are pinned and subjected to axial load and equal moment at the ends. The local buckling in the component plates is allowed for by using piecewise linear stress-strain curves that are approximations of previous research findings.

Shear strength of webs in box girder bridges
Journal of Constructional Steel Research, 1994Abstract In a box girder the slenderness of the flanges is usually considered to be much larger than in a plate girder. As a result, existing calculation methods suggest neglecting the flange contribution to anchor the diagonal tension band and thus to the ultimate shear strength.

Prediction of bending strength of long corrugated boxes
Packaging Technology and Science, 2001AbstractLong corrugated boxes were supported at both ends and bent by a concentrated force applied at the middle. Boxes with different lengths, cross‐sectional shapes, flute directions and board strengths were tested, using a standard compression tester with a fixed platen in accordance with ASTM D‐642.

Ultimate Strength of Skew RC Box Girder Bridge
Journal of the Structural Division, 1982Analytical and experimental results obtained in a study of a large-scale 45° skew two span four cell reinforced concrete box girder bridge model are presented. The model, which was a 1:2.82 scale replica of a typical California highway system prototype, had overall dimensions of 72 ft (21 m) long by 12 ft (3.7 m) wide, with two spans and a skew center ...

On MARS’s s-boxes Strength against Linear Cryptanalysis
2003MARS's s-boxes were generated using a new algorithm developed by the IBM team, which was supposedly able of producing secure s-boxes against both differential and linear cryptanalysis. In this paper we show this is not the case, because their strength against linear cryptanalysis is not better (in fact, it seems to be worse) that what could be expected
