Diaphragms for Curved Box Beam Bridges

Journal of the Structural Division, 1975
A finite difference procedure is used to determine the response of a single span curved single box beam bridge with any number of interior diaphragms. The bending and torsional distortions as well as cross-sectional distortions can then be determined throughout the curved box girder. The forces that are determined include bending moment and shear, pure

Aeroelastic tailoring of composite box beams

35th Aerospace Sciences Meeting and Exhibit, 1997
Aeroelastic instabilities are an important factor in the design of modern high-speed, flexible aircraft. The current trend is toward the creative use of composites to delay these instabilities. To obtain an optimum design, an accurate as well as efficient model is required.

Elastic Behavior of Box Beams

Journal of the Aeronautical Sciences, 1937
] \ / f ANY studies have been made of the elastic be^-*havior of the structure of airplane wings and a number of theories have been advanced as a result of these studies. In general, however, it may be said that too little attention has been directed in these studies to the properties of the shear webs and their relative importance in defining the ...

Investigation of the Instability of FGM box beams

Structural Engineering and Mechanics, 2015
A 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 ...

Finite element beam analysis of tapered thin-walled box beams

Thin-Walled Structures, 2016
Abstract This paper presents a one-dimensional finite element analysis of tapered thin-walled box beams under out-of-plane loads and twisting moments by developing new C 0 -continuous tapered higher-order beam elements. While higher-order sectional deformations such as distortion were considered earlier, there was no theoretical or finite ...

Coupled damping vibrations of anisotropic box beams

2015 International Conference on Mechanics - Seventh Polyakhov's Reading, 2015
This paper suggests a mathematical model for damping vibrations of an anisotropic thin-walled bars. It provides numerical study results regarding the effect of reinforcing fiber orientation upon natural frequencies and mechanical loss coefficients for coupled vibrations of symmetric and asymmetric box beams. The paper shows that vibrations of symmetric

Impact behavior of pultruded composite box-beams

Composite Structures, 1996
Abstract Fiber reinforced plastics lack design codes and appropriate specifications for the structural engineer to use these materials as a construction material. The need for the development of definitive guidance and criteria for the design and performance of fiber reinforced plastics and composite materials is essential for widespread applications

Space behaviour of thin-walled box beams

Computers & Structures, 1993
Abstract This paper considers the generalized static and dynamic analysis of thin-walled beams with a single box cross-section. The general flexural, torsion-bending, distortion-bending and axial interactive behaviours are considered. The analysis involves shear deformation, internal and structural damping as well as the inertia parameters due to the

Tests on reinforced plywood box beams

Building Research and Practice, 1973
Traditional plywood box beams depend to a considerable extent on the strength of natural timber for their flanges, and for reasons of safety only the highest grade of timber should normally be used, particularly when it is not laminated or when there is an abrupt change of direction at midspan.
