Interaction between Bond and Deviation Forces in Spalling Failures of Arch-Shaped Members without Transverse Reinforcement

Sylvain Plumey, Aurelio Muttoni, Miguel Fernández Ruiz

This paper investigates the structural behavior of reinforced concrete (RC) arch-shaped members without transverse reinforcement subjected to bending. Such members have typical applications in tunnels, cut-and-cover structures, shells, vaults, ducts, silos ...

Reinforcement element for structural concrete construction

Aurelio Muttoni, Miguel Fernández Ruiz

A reinforcing element (10) for structural concrete construction comprising a rod- shaped bar (1 1 ) having a cross-sectional enlargement on at least one end thereof. The rod shaped member (11 ) comprises an elbow portion (12) on said at least one end being ...

Applications of Stress Fields to Assess the Behavior and Strength of Coupling Beams subjected to Seismic Actions

Aurelio Muttoni, Miguel Fernández Ruiz

Horizontal loading due to earthquake or wind is usually the governing action for design of reinforced concrete cores in medium to tall buildings. Building cores designed to resist these actions must be dimensioned to resist tributary vertical loads and lar ...

Design through an incremental approach: the Swiss experience

Aurelio Muttoni, Miguel Fernández Ruiz

In Switzerland, the current code for structural concrete published in 2003 privileged an incremental approach for design of new members or for assessment of existing structures with respect to a number of topics (shear, buckling, reinforcement detailing th ...

Modelling techniques to capture the backbone envelope behaviour of coupling beams subjected to seismic loading

Aurelio Muttoni, Miguel Fernández Ruiz, Neven Kostic

Structural R/C cores are a popular and efficient choice as lateral-load resisting system in medium to tall buildings. The walls of the cores typically present large openings providing access to elevators placed within them. Shear induced by lateral forces ...

Aplicaciones de los campos de esfuerzos cortantes en el análsis y dimensionamiento de losas de hormigón armado - Applications of shear fields for analysis and design of reinforced concrete slabs

Aurelio Muttoni, Miguel Fernández Ruiz

This paper investigates the mechanical behaviour and the load-carrying mechanisms of reinforced concrete slabs by means of shear fields. The suitability of various shear fields obtained from different approaches (elastic and plastic theory) is investigated ...

Applications of the critical shear crack theory to punching of R/C slabs with transverse reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz

The traditional approach of codes of practice for estimating the punching strength of shear-reinforced flat slabs is based on the assumption that concrete carries a fraction of the applied load at ultimate while the rest of the load is carried by the shear ...

Non-symmetrical punching of flat slabs and slab bridges without transverse reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar

Punching of flat slabs without transverse reinforcement has mostly been investigated in the past for slabs with equal reinforcement ratios in the two directions and loaded under axis-symmetrical conditions. However, in practice, slab bridges as well as man ...

Shear strength in one- and two-way slabs according to the critical shear crack theory

Aurelio Muttoni, Miguel Fernández Ruiz

Currently, there is no generally-accepted theory giving a physical explanation of the shear strength in one- and two-way slabs. Furthermore, for members without transverse reinforcement, shear strength is estimated in most codes of practice following empir ...

Shear strength of members without transverse reinforcement as function of critical shear crack width

Aurelio Muttoni, Miguel Fernández Ruiz

This paper investigates the shear strength of beams and one-way slabs without stirrups based on the opening of a critical shear crack. The shear-carrying mechanisms after the development of this crack are investigated. On this basis, a rational model is de ...

Enhanced safety with post-installed punching shear reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz

A considerable number of flat slabs supported by columns need to be strengthened against punching shear. Reasons are increasing loads, construction or design errors, but also more stringent code requirements due to the increased knowledge gained in the pas ...

Shear strength of thin-webbed post-tensioned beams

Aurelio Muttoni, Miguel Fernández Ruiz

This paper investigates the load-carrying mechanisms and the strength of thin-webbed, post-tensioned beams failing by crushing of the web. The shear strength in these members is significantly reduced because of the state of cracking in the web and because ...

Influence of tensile properties of UHPFRC on size effect in bending

Aurelio Muttoni, Ana Spasojevic, Dario Redaelli, Miguel Fernández Ruiz

Bending behaviour of members without ordinary reinforcement made of quasi-brittle materials (such as concrete or fibre-reinforced concrete) is subjected to size effect both in terms of strength and ductility. For a typical ultra-high performance fibre-rein ...
