Shear Strength of Members without Transverse Reinforcement Based on Development of Critical Shear Crack

Miguel Fernández Ruiz, Francesco Cavagnis, João Tiago Ramos Bernardo de Santa Rita Simões

The shear strength of beams and one-way slabs has been acknowledged for more than one century as one of the most complex, yet fundamental, topics to be addressed in structural concrete design. The experimental data used to investigate the phenomenon has tr ...

An analysis of the shear-transfer actions in reinforced concrete members without transverse reinforcement based on refined experimental measurements

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Cavagnis

A traditional difficulty in the understanding of the role of the various shear transfer actions in members without transverse reinforcement has been a lack of detailed measurements on the development of shear cracking and their associated kinematics during ...

A mechanical model for failures in shear of members without transverse reinforcement based on development of a critical shear crack

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Cavagnis

In this paper, a mechanical model consistent with the main assumptions of the Critical Shear Crack Theory (CSCT) is proposed for shear design of slender concrete members without shear reinforcement. To that aim, the shear force that can be transferred thro ...

Shear in reinforced concrete without transverse reinforcement : from refined experimental measurements to mechanical models

Francesco Cavagnis

Since the first applications of structural concrete, the shear behaviour of one-way slabs without transverse reinforcement has been largely investigated. Nevertheless, currently in the scientific community there is no general agreement on the mechanisms of ...

Analysis of shear transfer actions in reinforced concrete members using refined measurement techniques

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Cavagnis

Detailed investigations on the role of the shear transfer actions in members without transverse reinforcement have traditionally been limited due to the possibilities offered by conventional measurement techniques. The main difficulty of such conventional ...

Shear failures in reinforced concrete members without transverse reinforcement: An analysis of the critical shear crack development on the basis of test results

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Cavagnis

Shear in concrete members without transverse reinforcement can be carried by various potential sheartransfer actions, whose activation depends much on the actual cracking pattern and kinematics at failure. Failures can occur in a progressive manner (at the ...
