A Mechanical Approach for the Punching Shear Provisions in the Second Generation of Eurocode 2

Aurelio Muttoni, Miguel Fernández Ruiz, João Tiago Ramos Bernardo de Santa Rita Simões, Duarte Miguel Viúla Faria

The revision of a code is a long-term project that shall fulfil several aims, comprising the enhancement of the ease-of-use and incorporating updated state-of-the-art. With respect to the revision of Eurocode 2 concerning the punching shear provisions, thi ...

Strength of reinforced concrete footings without transverse reinforcement according to limit analysis

Aurelio Muttoni, Miguel Fernández Ruiz, Duarte Miguel Viúla Faria, João Tiago Ramos Bernardo de Santa Rita Simões

Isolated footings are reinforced concrete elements whose flexural and punching shear strengths are usually governing for their design. In this work, both failure modes and their interaction are investigated by means of the kinematical theorem of limit anal ...

Bond behaviour of straight, hooked, U-shaped and headed bars in cracked concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Duarte Miguel Viúla Faria, Fabio Brantschen

Most classic investigations on bonding properties in reinforced concrete have been performed on the basis of pull-out tests, where a reinforcement bar is pulled out from an uncracked concrete cylinder, prism or cube. In these tests, the bond is governed by ...

Limit Analysis for Punching Shear Design of Compact Slabs and Footings

Aurelio Muttoni, Miguel Fernández Ruiz, Duarte Miguel Viúla Faria, João Tiago Ramos Bernardo de Santa Rita Simões

In this paper, the kinematical theorem of limit analysis is used to obtain the governing failure mechanisms and the corresponding failure load of reinforced concrete footings without transverse reinforcement. To that purpose, a Mohr-Coulomb yield criterion ...

SFRC flat slabs punching behaviour - Experimental research

António Manuel Pinho Ramos, Duarte Miguel Viúla Faria

The use of randomly distributed steel fibres in the concrete mix improves its mechanical properties. In the particular case of a flat slab-column connection, this solution can provide slabs with an increased load capacity and deformation capacity, allowing ...

On the efficiency of flat slabs strengthening against punching using externally bonded fibre reinforced polymers

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul, António Manuel Pinho Ramos, Duarte Miguel Viúla Faria

One possibility for strengthening existing flat slabs consists on gluing fibre reinforced polymers (FRPs) at the concrete surface. When applied on top of slab–column connections, this technique allows increasing the flexural stiffness and strength of the s ...
