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

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 ...

Punching shear strength of R/C bridge cantilever slabs

Aurelio Muttoni, Rui Vaz Rodrigues, Miguel Fernández Ruiz

This paper presents the results of six tests on R/C bridge cantilever slabs without shear reinforcement subjected to concentrated loading. The specimens represent actual deck slabs of box-girder bridges scaled 3/4. They were 10mlong with a clear cantilever ...

A re-evaluation of test data on bond in R/C by means of FEM modeling

Aurelio Muttoni, Miguel Fernández Ruiz, Pietro Gambarova

The role of various parameters governing bond behavior is investigated in this paper taking advantage of a simple but efficient finite-element model, whose fundamental aspects are briefly recalled. Several well-documented test results on bond are examined ...

Concrete Cracking in Tension Members and Application to Deck Slabs of Bridges

Aurelio Muttoni, Miguel Fernández Ruiz

Currently, estimations of the crack width in the deck slab of bridges given by codes of practice are based on either theoretical or empirical approaches considering mainly the monotonic loading behaviour. However, cracking in reinforced tensile members is ...

On Development of Suitable Stress Fields for Structural Concrete

Aurelio Muttoni, Miguel Fernández Ruiz

Strut and tie models and stress fields are methods that can be used for the dimensioning and detailing of reinforced and prestressed concrete structures as well as for the check of existing ones. This paper presents an innovative approach towards the autom ...

Analytical modeling of the pre- and post-yield behaviour of bond in reinforced concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Pietro Gambarova

This paper presents the theoretical basis and the main results of an analytical model that describes the pre– and post–yield response of bond in reinforced concrete, as well as its influence on the behavior of structural members. The model is based on a nu ...

Computer-aided development of stress fields for the analysis of structural concrete

Olivier Burdet, Aurelio Muttoni, Miguel Fernández Ruiz

The stress field method is a technique based on the lower-bound theorem of plasticity that can be used for dimensioning, detailing and checking of structural concrete elements. Its use has been traditionally associated with the assumption of simplified (ri ...

Tensile Behaviour of reinforced ultra-high performance fiber reinforced concrete elements

Aurelio Muttoni, Dario Redaelli

Ultra-high performance fiber reinforced concrete (UHPFC) is a new class of materials that combine a very strong and dense cementicious matrix with a high fiber content. UHPFC has a very high compressive strength (in the order of 200 MPa) and a relatively l ...

Experimental investigation on the load-carrying capacity of thin webs including post-tensioning tendons

Eckart Hars, Aurelio Muttoni, Miguel Fernández Ruiz

The presence of post-tensioning tendons in webs decreases the load-carrying capacity of the compression struts that are necessary to transfer shear forces. This effect has been known for a long time, but was initially not included in design codes. In parti ...
