Deformation capacity evaluation for flat slab seismic design

Aurelio Muttoni, Lorenzo Martinelli, António Manuel Pinho Ramos, Andri Setiawan

In flat-slab frames, which are typically designed as secondary seismic structures, the shear failure of the slab around the column (punching failure) is typically the governing failure mode which limits the deformation capacity and can potentially lead to ...

Seismic Performance of Strengthened Slab-Column Connections in a Full-Scale Test

Aurelio Muttoni, António Manuel Pinho Ramos

Strengthening of flat slab-column connections to resist imposed lateral drifts is often required for older reinforced concrete structures in which the flat slabs were typically designed to resist gravity load only or have been designed for less stringent r ...

Testing of a full-scale flat slab building for gravity and lateral loads

Aurelio Muttoni, António Manuel Pinho Ramos

Full-scale testing of a two-storey flat slab structure is reported, undertaken in the SlabSTRESS research project; the construction and testing were planned and carried out at the ELSA laboratory of the European Commission's Joint Research Centre. The dime ...

A state of the art of flat-slab frame tests for gravity and lateral loading

Aurelio Muttoni, António Manuel Pinho Ramos

This paper presents a critical review of the state of the art of experimental research concerning the seismic response of reinforced concrete flat slab frames. After a summary of tests on connections, the paper examines tests carried out on frames with gra ...

Influence of prestressing on the punching strength of post-tensioned slabs

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

Previous researches on punching of post-tensioned slabs have shown a number of phenomena significantly influencing their strength and behaviour. However, no general agreement is yet found on a physical theory (either in codes of practice or in design model ...

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 ...

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 ...
