High-Strength Concrete Deep Beams With Effective Span and Shear Span Variations

ACI Structural Journal, 1995
Nineteen reinforced concrete deep beams with compressive strengths in the range of 41 MPa ≤ f' c ≤ 59 MPa (6000 psi ≤ f' c ≤ 8600 psi) were tested under two-point top loading. All the beams were singly reinforced with main steel percentage p = 1.23 percent and with nominal percentage of shear reinforcement ρ v = 0.48 percent.

AFRP Fabric Strengthening along Shear span in Shear deficient beams

International Journal on Science and Technology
In this study, AFRP (Aramid Fiber Reinforced Polymer) Fabric were utilized to externally strengthen the shear deficient beams in the shear span. Shear deficient beams externally strengthened with varying thickness of AFRP in Shear span and two layers of AFRP Strip of 50 mm width at the bottom of the beam are modeled and analysed.

Shear-Lag Effects in Three-Span Continuous Box Girder

Applied Mechanics and Materials, 2011
The physical explanation of shear lag is given in this paper. The shear lag effects can be attributed to the abrupt change of shear stress at web-flange junction. The abrupt change at the junction of shear stresses changes the magnitude of the flange bending stresses, which attenuates gradually with increasing distances from the web.

Shear behavior of RC beams reinforced with internal trussed steel strips at shear span zone

Structures, 2021
Abstract This paper presents an experimental study on the shear performance of reinforced concrete (RC) beams provided with pre-prepared steel trusses in the shear span zone. Those steel trusses were assembled using electrical welding for steel strips of 2 mm thickness.

Shear behavior of two-span fiber reinforced concrete beams

Archives of Civil and Mechanical Engineering, 2019
Abstract The presented study was conducted to assess the shear capacity and the mechanical behavior of fiber reinforced concrete two-span beams in a five-point bending test. Experimental research was focused on observing changes in the behavior of tested elements depending on the amount of shear reinforcement (stirrups) and the fiber type used.

Indirect Loading on Beams with Short Shear Spans

ACI Journal Proceedings, 1977
A study of the effect of loading and supporting conditions on the behavior and ultimate shear strength of beams with short shear spans is presented. Previous experimental work by the authors has been extended to include a shear span-to-depth ratio = 2. The overall findings of the investigation are summarized.

Shear Behavior of Large-Scale Post-Tensioned Girders with Small Shear Span-Depth Ratio

ACI Structural Journal, 2010
Although there have been several studies on the shear behavior of prestressed concrete beams, these generally focused on shear capacity rather than shear deformation. The present study investigated the shear deformation of large-scale reinforced I-shaped girders and post-tensioned prestressed concrete girders with a small shear span-depth ratio of 2.5.

Experiments on thin airfoils spanning a transonic shear flow

1976
A wind tunnel was built at the California Institute of Technology to provide two uniform coflowing streams at Mach numbers of 0.6 and l.4 with a plane mixing layer in between. Preliminary studies were made of this free shear layer, indicating a region of self-similar behavior and general agreement in growth rate with previous studies.

Experimental Investigation of Trapezoidal Profile Sheeting under Varying Shear Spans

Applied Mechanics and Materials, 2016
Composite construction method has been mainly popular due to its faster, lighter and economical methods in high rise buildings. Composite deck slab consisting of two different components, concrete being good in compression placed at the upper portion and the cold form profiled sheeting being good in resistance to tension is placed at the bottom of the ...
