TLDR
In this paper, an extensive test program for the investigation of the SHEAR RESISTANCE of reinforced CONCRETE beams was carried out and the results of these tests led to the classification of SHEAR FAILURES into four basic models: DIAGONAL TENSION, SHEARING, SHARING COMPRESSION, and WEB CRUSHING.Abstract:
AN EXTENSIVE TEST PROGRAM FOR THE INVESTIGATION OF THE SHEAR RESISTANCE OF REINFORCED CONCRETE BEAMS WAS CARRIED OUT. SIXTY-THREE T, I, AND RECTANGULAR BEAMS WITH VARYING CROSS SECTION, WEB REINFORCEMENT, LONGITUDINAL REINFORCEMENT, CONCRETE STRENGTH, AND SHEAR SPAN WERE TESTED. STUDY OF THESE AND OTHER RESULTS LEAD TO THE CLASSIFICATION OF SHEAR FAILURES INTO FOUR BASIC MODES. THESE MODES ARE DESCRIBED AND EQUATIONS DEVELOPED FOR THE CALCULATION OF COLLAPSE LOADS FOR FAILURES BY DIAGONAL TENSION, SHEARING, SHEAR COMPRESSION, AND WEB CRUSHING. THE ULTIMATE LOAD IN A GIVEN CASE IS INTRINSIC TO THE FAILURE MODE CORRESPONDING TO THE LEAST STRENGHT AFTER DIAGONAL CRACKING. A FORMULA FOR CALCULATING SHEAR CRACK WIDTHS IS PRESENTED. /AUTHOR/read more

Shear capacity in concrete beams reinforced by stirrups with two different inclinations
TL;DR: In this paper, a model for the estimation of shear capacity in reinforced concrete (RC) beams with web reinforcement is provided by introducing a generalization of classical plastic Nielsen's model, which is based on the variable-inclination stress-field approach.

Shear strength of RC beams without web reinforcement
TL;DR: A numerical mechanics-based segmental approach for the shear failure of RC beams with any type of reinforcement and concrete is developed and compared to the predictions made by the ACI, AS 3600 and FIB Model Code 2010 approaches show that the proposed approach offers improved accuracy and a reduction in scatter.

Bio-inspired predictive models for shear strength of reinforced concrete beams having steel stirrups
TL;DR: Three bio-inspired predictive models are proposed with the aim of estimating the shear capacity of reinforced concrete (RC) beams having steel stirrups and it was concluded that the proposed mathematical frameworks could determine theShear capacity with a satisfactory level of precision in comparison with the obtained results of ACI-318.

Shear behaviour of prestressed double tees in self-compacting polypropylene fibre reinforced concrete
TL;DR: In this paper, the use of macro-synthetic fibres as shear reinforcement in self-compacting concrete prestressed double tees is investigated. And the experimental results of full-scale tests on six prestressed triple tees made in self compact concrete and self compacting polypropylene fiber reinforced concrete are presented.
