A new perspective on the punching resistance of edge columns with and without shear reinforcement applying refined measurement techniques

Despite edge columns being instrumental components of flat slabs, most punching research has focused on internal connections. Several particularities of edge columns, such as load eccentricity and moment transfer, require additional experimental investigat ...

Punching of edge columns with and without shear reinforcement: an experimental investigation

Aurelio Muttoni, Diego Hernández Fraile, Andri Setiawan, Júlia Borges Dos Santos

Most research efforts in the past related to the punching resistance of reinforced concrete slabs have concentrated on the response of internal slab-column connections, where significant advances in the state-of-the-art have been performed. Other than inte ...

Enhancing Punching Strength and Deformation Capacity of Flat Slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone

Punching reinforcement systems have significantly developed in recent years as they allow enhancing the punching resistance of slab-column connections as well as their deformation capacity. These systems, with varying geometry and layout, normally consist ...

Effect of laser rescanning on the grain microstructure of a selective laser melted Al-Mg-Zr alloy

Christian Leinenbach

The microstructures of alloys created via Additive Manufacturing (AM) can vary substantially from those present in cast or wrought products, due to the very rapid solidification associated with AM. While numerous studies have investigated the process-micro ...

Shell Modelling Strategies for the Assessment of Punching Shear Resistance of Continuous Slabs

Aurelio Muttoni, Raffaele Cantone, Beatrice Belletti

The punching shear resistance formulation provided by Model Code 2010 is calibrated on the basis of experimental tests on isolated slabs supported on columns. According to Level of Approximation approach, several quantities are required for the design punc ...

Parametric analysis on punching shear resistance of reinforced concrete continuous slabs

Aurelio Muttoni, Beatrice Belletti

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). However, the behaviour of actua ...

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 ...

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 ...

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 ...
