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 ...
Engineering Structures2016Study on Influence of Column Size and Slab Slenderness on Punching Strength
Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul
This paper presents the results of a systematic experimental campaign consisting of 13 symmetric punching tests on interior slab-column connections. The study focuses on the influence of varying the size of the supported area and the slenderness of the sla ...
ACI Structural Journal2016Stress Fields for the analysis of the faillure load and cracking state of dapped-end beams (Aplicación de modelos de campos de tensiones para el análisis en servicio y rotura de apoyos a media madera)
Aurelio Muttoni, Miguel Fernández Ruiz, Jaime Mata Falcon
The automatic generation of elastic-plastic stress fields (EPSF) for structural concrete members by means of the finite element method has been demonstrated as a suitable approach for the design and assessment of D regions. This methodology allows accounti ...
VI Congreso ACHE2014Influence of longitudinal reinforcement layouts on RC wall performance
Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso, Raluca-Tereza Constantin
Design recommendations for longitudinal reinforcement layouts of reinforced concrete (RC) walls have been derived from plane section analyses. Such an analysis generally favours wall layouts with boundary elements containing large amounts of vertical reinf ...
2014Experimental Investigation on Punching Strength and Deformation Capacity of Shear-Reinforced Slabs
Aurelio Muttoni, Miguel Fernández Ruiz, Stefan Lips
The authors report on punching tests with full-scale slab specimens. The objective was to investigate the influence of several parameters on the punching strength and rotation capacity of flat slabs ...
American Concrete Institute2013Punching shear strength of steel fibre reinforced concrete slabs
Aurelio Muttoni, Miguel Fernández Ruiz, Luis Felipe Maya Duque
The ultimate strength of reinforced concrete slabs is frequently governed by the punching shear capacity, which may be increased with addition of traditional fitments such as reinforcing steel, headed studs or shear heads. In addition to these traditional ...
Engineering Structures2012Structural Response of R-UHPFRC - RC Composite Members Subjected to Combined Bending and Shear
The addition of a thin overlay of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) to Reinforced Concrete (RC) members is an emerging technique to strengthen and protect existing structures and to design durable new structures. Combining UHPFRC wi ...
EPFL2012Experimental Investigation on Punching Strength and Deformation Capacity of Shear-Reinforced Slabs
Aurelio Muttoni, Miguel Fernández Ruiz, Stefan Lips
This paper presents the results of an extensive experimental campaign on 16 flat-slab specimens with and without punching shear reinforcement. The tests aimed to investigate the influence of a set of mechanical and geometrical parameters on the punching sh ...
ACI Structural Journal2012Non-axis-symmetrical punching shear around internal columns of RC slabs without transverse reinforcement
Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar, Luca Tassinari
Most analytical approaches and available test data for punching shear in flat slabs assume axis-symmetrical conditions, which seems realistic for representing slabs supported on columns equally spaced in both orthogonal directions. However, in practice, th ...
Magazine of Concrete Research2011Poinçonnement non symétrique des dalles en béton armé
Punching shear of reinforced concrete flat slabs supported on columns is a failure mode in which the slab fractures around the column. This type of failure is sudden and can be catastrophic in nature. Punching shear generally governs the ultimate limit sta ...
