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 ...

Performance of punching shear reinforcement under gravity loading: Influence of type and detailing

Aurelio Muttoni, Miguel Fernández Ruiz, Fabio Brantschen, Jürgen Einpaul

The performance of 11 different shear reinforcement systems against punching of inner slab-column connections under gravity loading was compared on the basis of experiments on 12 full-scale specimens, 8 of them newly reported. The slab geometry and flexura ...

Compressive Membrane Action Effects on Punching Strength of Flat RC Slabs

Aurelio Muttoni, Raffaele Cantone, Luca Manelli, Beatrice Belletti

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 ...

Internal slab-column connections under monotonic and cyclic imposed rotations

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

Reinforced concrete flat slabs supported by slender columns are often used as gravity load resisting system for buildings in regions of moderate seismicity. Current codes of practice determine the displacement capacity of slab-column connections using empi ...

Thermal and structural performance of a new fiber-reinforced polymer thermal break for energy-efficient constructions

Kyriaki Goulouti

The thermal bridges constitute critical regions in building envelopes and they are created due to the interruption of the insulation layer. One of the many structural thermal bridges in building envelopes is created in balcony junctions because of the requ ...

Static and Fatigue Shear Strength of Reinforced Concrete Slabs Under Concentrated Loads Near Linear Supports

Francisco Manuel Maciel Natário

Reinforced concrete slabs without shear reinforcement under concentrated loads near linear supports are typical cases of bridge deck slabs, transfer slabs or pile caps. Such members are often designed or assessed in shear/punching shear with code provision ...

Temperature effects on material properties and structural response of polymer matrix composites

Wei Sun

Structural components used in civil engineering applications are often subjected to compressive loads. Unlike the tensile strength of fiber-reinforced polymer (FRP) materials, their compressive strength is resin-dominated, exhibiting lower values and more ...

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 ...
