Punching strength of continuous flat slabs

Reinforced concrete slabs with uniform thickness are common in residential and commercial buildings but can also be found in other types of structures. Such slabs are susceptible to punching shear failures, where a supporting column penetrates through the ...

Compressive Membrane Action Effects on Punching Strength of Flat RC Slabs

Aurelio Muttoni, Raffaele Cantone, Beatrice Belletti, Luca Manelli

The design of reinforced concrete flat slabs in practice can be governed at failure by punching shear close to concentrated loads or columns. Punching shear resistance formulations provided by codes are calibrated on the basis of experimental tests on isol ...

Influence of moment redistribution and compressive membrane action on punching strength of flat slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

The punching shear strength of interior column connections of flat slabs has traditionally been investigated with isolated test specimens subjected exclusively to hogging bending moments. However, the behavior of such specimens is different from that of ac ...

Design for punching of prestressed concrete slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Thibault Clément, António Manuel Pinho Ramos

Prestressing in flat slabs helps in controlling deformations and cracking under service loads and allows reducing the required slab thickness, leading thus to more slender structures and being therefore an economic solution for long spans. However, as a co ...

Effect of transverse load on the critical current of a coated conductor Roebel cable

Pierluigi Bruzzone, Davide Uglietti, Rainer Wesche

Roebel cables are one possible option for use in the manufacture of high current conductors for various technical applications. In this work the behaviour of critical current under transverse loads up to 90 MPa was studied in coated conductor Roebel cables ...

New provisions for punching shear in Model Code 2010 based on the Critical Shear Crack Theory

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar, Luca Tassinari

The provisions for punching shear around concentrated loads in the new Model Code 2010 (MC2010) have been updated, covering a large number of design cases such as slabs with and without transverse reinforcement, different column/slab geometries and prestre ...
