Flexural shear behavior of FRHSC beams with fibers only in shear span

Materials Today: Proceedings, 2022
Abstract As per Code of Indian Standards, a concrete having a compressive strength greater than or equal to 65 N/mm2 is referred to as a high strength concrete. High strength concrete has many favorable properties, but it is a brittle material and has a low rate of increase of tensile strength due to which it is not of great use in earthquake-prone ...

Effect of shear span-to-depth ratio on mechanical performance and cracking behavior of high strength steel fiber-reinforced concrete beams without conventional reinforcement

Mechanics of Advanced Materials and Structures, 2020
Flexural behavior of reinforced concrete beams was affected by the shear span-to-depth ratio (a/d), but a/d was not mentioned in design guidelines for the steel fiber-reinforced concretes (SFRCs).

CFRP Repair of RC Beams with Shear-Span and Full-Span Corrosions

Journal of Composites for Construction, 2010
This paper presents experimental and analytical results of a study conducted to investigate the use of carbon fiber-reinforced polymer (CFRP) laminates to rehabilitate shear-span and full-span corrosion-damaged RC beams. Fifteen RC beams were fabricated and were divided into three groups: control, shear-span, and full-span corrosions.

Critical shear span ratio of bend and shear cracking of masonry wall

2011 International Conference on Multimedia Technology, 2011
Critical shear span ratio of bend and shear cracking of brick wall is studied in order to determine and control configuration of bend and shear failure of masonry bearing walls subjected to horizontal action. The concept of critical shear span ratio between bend and shear cracking is set forth firstly, and the analysis principle of critical shear span ...

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.

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.
