...Hamed Sadaghian; Seyed Saeed Mirrezaei; Masood Farzam Studies on the punching shear of reinforced concrete (RC) slabs exposed to fire are very limited. To address this shortcoming, a series of numerical analyses were carried out to study the effects of several parameters on punching shear behaviour...

...Saumyaranjan Sahoo; Bhupinder Singh For this paper, the punching shear behaviour of 18 steel-fibre recycled aggregate concrete (SFRAC) balanced slab–column connections was experimentally investigated and analytically modelled for the following variables: the recycled concrete aggregate replacement...

... connections after punching shear failure (post-punching shear). The proposed model considers the gradual activation and deactivation of flexural bars within and outside the punching shear cone as well as the contribution of integrity reinforcement. The model is formulated in terms of slab vertical...

...Jaroslav Halvonik; Lucia Majtánová; Maria Minarova This paper deals with an evaluation of the generalised partial safety factor for resistance properties by using a statistical determination of a resistance model for predicting the punching capacity. The factor takes the material, model...

...Andri Setiawan; Robert L. Vollum; Lorenzo Macorini; Bassam A. Izzuddin This paper utilises non-linear finite-element analysis with three-dimensional (3D) solid elements to gain insight into the role of shear reinforcement in increasing punching shear resistance at internal columns of flat slabs...

...Huizhong Xue; Hong Guan; Benoit P. Gilbert; Xinzheng Lu; Yi Li The punching and post-punching shear behaviours of reinforced concrete (RC) flat plate structures are often studied by using a representative slab–column connection isolated from the parent structure. In this study, a set of numerical...

...Dominik Kueres; Josef Hegger; Maria Anna Polak Punching tests on continuous concrete slabs are very expensive and elaborate. As a consequence, the majority of the existing punching tests have been performed on isolated specimens representing only the hogging moment region around the considered slab...

...Dominik Kueres; Josef Hegger According to previous investigations, prestressing has various positive influences on punching shear behaviour of reinforced-concrete slabs. While in-plane compressive stresses and decompression moments reduce the slab deformations, leading to an increased punching...

...André F. O. Almeida; Bruno Alcobia; Miguel Ornelas; Rui Marreiros; António Pinho Ramos This paper describes the experimental campaign to study the behaviour of reinforced-concrete flat slab structures with steel stirrups as punching shear reinforcement, under combined vertical and horizontal cyclic...

...Hussam A. Goaiz; Nabeel A. Farhan; M. Neaz Sheikh; Tao Yu; Muhammad N. S. Hadi This study presents an experimental evaluation of three different methods for determining the tensile strength of steel fibre reinforced concrete (SFRC). The test methods include the splitting test (ST), double punch...

...Beatrice Belletti; Aurelio Muttoni; Simone Ravasini; Francesca Vecchi Punching shear resistance formulations provided by codes are usually calibrated on test results of isolated specimens that typically simulate the slab zone within the points of contraflexure around the column (hogging area...

... reserved 2018 failure fibre-reinforced concrete punching The use of flat slabs in buildings is widespread nowadays as, for this structural solution, the slabs are directly supported by the columns, without the need for beams, which has inherent advantages. However, this type of construction...

... ratios and were located at the centre of the plates. The load was applied with specified eccentricities and was increased monotonically. The failure mode of all plates was brittle punching. Furthermore, the effect of eccentricity of loads on the ultimate punching resistance and rotational capacity...

...Jürgen Einpaul; Miguel Fernández Ruiz; Aurelio Muttoni Advancing the knowledge about the punching behaviour of flat slabs has been held back by the fact that only indirect measurements of the internal failure mechanism have typically been available. In this paper, a novel experimental approach...

...Massimo Lapi; Hugo Fernandes; Maurizio Orlando; António Ramos; Válter Lúcio Punching strengthening of reinforced-concrete slabs using a bonded reinforced-concrete overlay (BRCO) is an efficient alternative to traditional strengthening systems such as post-installed shear reinforcement, enlargement...

...Luis Fernando S. Soares; Robert Lars Vollum The paper considers punching failure at edge columns of reinforced concrete flat slabs without shear reinforcement and unbalanced moments about an axis parallel to the slab edge. Edge column punching shear tests have been carried out on a variety...

... from flexure to punching shear. After describing the specimens and the test rig characteristics, the experimental results and observations are analysed and discussed. Particular emphasis is given to the governing factors that affect the behaviour and failure mode of the slabs. In addition, the test...
