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 ...

Punching strength of continuous flat slabs

Jürgen Einpaul

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 ...

Experimental investigation on punching resistance of R-UHPFRC–RC composite slabs

Eugen Brühwiler, Maléna Bastien Masse

An effective method to strengthen existing Reinforced Concrete (RC) structures is to add a thin layer of Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC), with or without steel rebars, over the concrete slab to create a composite ele ...

Punching shear capacity of continuous slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

Provisions for punching shear design of reinforced concrete slabs are usually calibrated on the basis of results from tests on isolated specimens that simulate the slab zone within the points of contraflexure around a column. However, the punching behavior ...

Seismic behaviour of slab-column connections without transverse reinforcement

Ioannis Sokratis Drakatos

Reinforced concrete (RC) flat slabs supported by slender columns are often used as gravity load resisting system for buildings in regions of moderate and high seismicity. Such buildings are typically braced by RC walls, which carry the largest portion of t ...

Fatigue behavior of hybrid GFRP-concrete bridge decks under sagging moment

Haifeng Fan, Yuqing Liu

This paper presents a new cost-effective hybrid GFRP-Concrete deck system that the GFRP panel serves as both tensile reinforcement and stay-in-place form. In order to understand the fatigue behavior of such hybrid deck, fatigue test on a full-scale specime ...

Effect of Deformation History on Punching Resistance of Reinforced Concrete Slabs

Robert Koppitz

Deformation-dependent punching shear resistance often constitutes the decisive design criterion for reinforced concrete slabs supported by columns. The increasing number of aging structures exhibiting insufficient punching resistance and detailing deficien ...

Design and experimental verification of an innovative steel–concrete composite beam

Jean-Paul Lebet, Dimitrios Papastergiou

This paper deals with the design method and the experimental verification of a new type of steel–concrete composite beam under static and fatigue loading. The connection is an alternative solution for steel–concrete composite bridges suitable for prefabric ...

Punching strength of actual two-way slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

Many building codes rely on empirical formulations with respect to the punching shear design provisions. Such empirical equations are typically calibrated on the basis of laboratory tests performed on simplified geometries (usually isolated specimens) with ...
