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.

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.

Effect of transverse steel and shear span on the performance of RC beams strengthened in shear with CFRP

Composites Part B: Engineering, 2006
This paper presents results of an experimental investigation involving twelve tests on 3000 mm-long reinforced concrete (RC) T-beams strengthened in shear with externally bonded carbon fiber reinforced polymer (CFRP) composites. The main objective of this study was to evaluate the effect of the following parameters on the shear performance of ...

Effects of stirrup ratio and shear–span ratio on shear failure of geometrically similar RC columns

Magazine of Concrete Research, 2023
Very few studies have been dedicated to the size effect on the shear behaviour of reinforced concrete (RC) columns. In particular, there lacks a design equation that can quantitatively represent the effect of related parameters on the size effect on nominal shear strength for RC columns.

The effect of shearing stress on the span calculations of a suspended cable

Journal of the Institution of Electrical Engineers, 1923
The paper presents the complete equation of a suspended cable, taking into account its density, elasticity and rigidity, and determines the extent to which the effect of shearing stress should be considered for practical span calculations. The criterion of the importance of flexural rigidity can be written in the form e=100 × 2γ=100Ed 2 D 3 /ρ(S/2)

Behavior of Concrete Beams with Short Shear Span and Web Opening Strengthened in Shear with CFRP Composites

Journal of Composites for Construction, 2012
This paper presents test results of 16 reinforced concrete (RC) beams with web openings strengthened in shear with externally bonded carbon fiber reinforced polymer (CFRP) composite sheets. Test specimen was 2,600 mm long with a cross section of 85 mm × 400 mm and a shear span to beam depth ratio of a=h ¼ 2. All specimens had the same geometry and main

Seismic behavior of shear-critical circular TSRC columns with a shear span-to-depth ratio of 1.3

Thin-Walled Structures, 2019
Abstract Beam-column connections of steel reinforced concrete (SRC) structures are complicated and difficult to be constructed due to the densely arranged longitudinal reinforcements and stirrups. One good alternative is to use the composite construction where the reinforcing cage in the SRC column is replaced by an outer thin-walled steel tube ...

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.
