The Dynamics of Box Beams

Journal of Aerospace Sciences and Technologies, 2023
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.

Curved box beam bridge analysis

Computers & Structures, 1976
Abstract 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,

Torsion in Box Beams

Aircraft Engineering and Aerospace Technology, 1942
To the Editor SIR, In the January issue of AIRCRAFT ENGINEERING (Vol. XIV, No. 158) there is an extremely interesting article by Payne on “Torsion in Box Beams”. Unfortunately, as with most rigid analyses, a considerable amount of work is necessary before arriving at the final distribution of the applied torque. The scope is also extremely limited.
