Shear behavior of ferrocement box beams

Cement and Concrete Composites, 1991
Abstract 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

Box-Beam Bursting Energy Absorbing Terminal

Journal of Transportation Engineering, 2002
A new box-beam guardrail end terminal, known as the box-beam bursting energy absorbing terminal (BEAT), was designed and shown to meet current United States impact safety standards according to guidelines provided by the National Cooperative Highway Research Program (NCHRP). The BEAT is placed on the end of a box-beam guardrail system. When impacted by

Box beams subject to torsion

International Journal of Mechanical Sciences, 1978
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.

LONGITUDINAL CRACK IN PRESTRESSED BOX BEAM

PCI Journal, 1969
A WIDE AND DEEP LONGITUDINAL CRACK DEVELOPED IN THE BOTTOM OF A BRIDGE BOX BEAM AND EXTENDED FROM ONE SUPPORT ALMOST TO MID-SPAN. A DETERMINATION OF THE MOST PROBABLE CAUSE OF THE CRACK AND AN EVALUATION OF THE ULTIMATE AND RESERVE STRENGTH OF THE BEAM BY LOAD TESTING TO FAILURE WERE MADE.

Box-Beam Active Rotor Blades

2015
The previous chapter clearly showed that shear-based piezoceramic actuation using \(d_{15}\) is feasible for obtaining active twist. The current chapter dwells more on the development and validation of the concept of induced-shear-based piezoceramic actuation in helicopter rotor blades considering a simple two-cell box cross section.

Prestressed Box Beams under Combined Loading

Journal of the Structural Division, 1975
Prestressed concrete box beams are studied under combined loadings of torsion, bending, and shear. Thirty-seven eccentrically prestressed beams were tested—three under pure torsion, 10 under varying ratios of torsion and bending, and 24 under varying ratios of torsion, bending and shear. All beams had a 12-in.

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.
