“…In the related works, concrete damage plasticity (CDP) model is widely used and is recognized with high-reliability in the analysis of concrete behavior. Many proposed models related to the nonlinear behavior of concrete were developed and improved from the original CDP [2][3][4][5][6][7]. An integral dynamic strength criterion for concrete was proposed [8].…”

This paper proposes a simple method for calculating the shear deformation and the shear capacity of reinforced and prestressed concrete elements containing shear reinforcement. This new approach considers that, for large deformations, concrete elements follow compatibility conditions based on displacements of the composite material subjected to shearing forces. The result is a beam, inspired by the Timoshenko-Ehrenfest beam theory, which considers a new hypothesis regarding shearing deformation, informed by the behavior of the shear reinforcement. The new method is compared with previous approaches, allowing us to assess the technological advances of the new proposal. The new method is easy to implement and provides information about the shearing deformation (in the elastic and plastic domains) and the shearing capacity of concrete beam-column elements. A detailed example is developed, in which all the components of the shear deformation are evaluated, and the simplification of the new method is analyzed in comparison with other more comprehensive methods in the elastic domain.

“…Besides, instead of using the stress-strain relationship of bare bars in the FASTM, the stress-strain relationship of steel bars wrapped in concrete is used. In order to study the bearing capacity of reinforced concrete beams, Vahid Broujerdian et al (2019) proposed an algorithm for predicting multiple shear cracks, load-deformation behaviour and ultimate CONTACT Ruisheng Feng fengruisheng2019@163.com shear capacity of reinforced concrete beams based on the discrete crack method. The results obtained were in good agreement with the existing benchmark test results of shear failure of reinforced concrete beams.…”

The traditional fixed-angle softened truss model (FASTM) procedure to compute the shear capacity of RC beams requires multiple iterations. The present paper analyzes the mechanical behaviours under the critical state of shear capacity of 367 RC simply supported beams with rectangular sections. Some significant regressions have been captured in the statistical analysis of these 367 beams. A straightforward method to calculate the shear capacity of RC beams with rectangular section is proposed by introducing an additional regression relation into FASTM. The calculation results corresponding to this explicit calculation method are in good agreement with the test values and traditional FASTM.
