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 ...

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 ...

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 ...

New experimental determination of fatigue strength of tubular truss joints in steel grades up to S690

Alain Nussbaumer, Farshid Zamiri Akhlaghi

In this paper research work on welded butt weld connections between hot-rolled seamless tubes and steel castings are presented. Comparison is made between different weld preparations for the butt welds including different steel grades, repair methods, the ...

Punching resistance and flexural behaviour of continuous flat slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

The punching resistance of actual reinforced concrete flat slabs is potentially influenced by the compressive membrane action, which may significantly increase their resistance compared to isolated laboratory specimens. However, design codes have been deve ...

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 ...
