Box beams bend essentially with top and bottom skins providing bending rigidity and shear webs giving shear flexibility. When the width of the beam is comparable to the length of the beam and considerably larger than the depth ofthe shearwebs, there is an added complication called the shear lag effect.

Investigation of the Instability of FGM box beams
Structural Engineering and Mechanics, 2015A general geometrically non-linear model for lateral-torsional buckling of thick and thin-walled FGM box beams is presented. In this model primary and secondary torsional warping and shear effects are taken into account. The coupled equilibrium equations obtained from Galerkin\'s method are derived and the corresponding tangent matrix is used to ...

Analysis of the vibration of box beams
Journal of Sound and Vibration, 1976Abstract The natural frequencies and mode shapes of a number of box beams are calculated by using the finite element displacement method. The structures are considered as assemblages of plates, and in general it is necessary to consider both the in-plane and transverse motion of the plates.

THE effect of axial constraint on box beams of approximately rectangular section, subject to torsion, is of interest to the aircraft designer in connexion with the stressing of two‐spar skin‐covered wings. The stresses due to torsion in a uniform box with one end built‐in have been investigated by D.

Connection of I-beam to box-column by a short stub beam
Journal of Constructional Steel Research, 2016Abstract Box-columns are frequently used in moment resisting frames due to the numerous advantages they offer. Accordingly, bolted extended end-plate moment connections are widely used in steel structures due to their advantages such as easy fabrication and fast erection. However, some problems such as inaccessibility to the inside of box-columns for

Shear behavior of ferrocement box beams
Cement and Concrete Composites, 1991Abstract The shear behavior of ferrocement box beams has been studied by conducting flexural tests on 15 beam specimens. The major parameters used were amounts of wire mesh reinforcement in webs and in flanges of the beam and shear span to depth ratio, a/h. Test results indicate that cracking and ultimate shear forces increase as wire mesh in webs is

Stress analysis is carried out for the case where a cantilever box beam is subjected to distributed torque and concentrated torque at the tip. Direct stress σx acting in a cover plate is assumed to be in the form of ∑n σn(x)yn where n is an odd integer and the fundamental equation governing a box beam is introduced, using variational method.

Curved box beam bridge analysis
Computers & Structures, 1976Abstract A finite difference procedure is used to determine the response of a single and multi span curved single box beam bridge with any number of interior diaphragms. The bending and torsional distortions as well as cross-sectional distortions are determined throughout the box girder. The forces that are determined include bending moment and shear,
