Influence of Load Duration on Shear Strength of Reinforced Concrete Members

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

The significance of sustained loading on the compressive and tensile strength of concrete has been experimentally verified since the 1950s and is currently acknowledged in most design codes implicitly or explicitly. However; its influence on other potentia ...

Time-dependent strength of concrete in compression and shear

Darko Tasevski

Sustained load actions are permanently present in concrete structures, as for example self-weight and dead loads on bridges or soil pressure on cut-and-cover tunnels. These actions may increase throughout a structure's lifetime, for instance after refurbis ...

Assessing the compressive strength of concrete under sustained actions: From refined models to simple design expressions

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

The detrimental influence of high levels of sustained load on the compressive strength of concrete has been acknowledged and investigated since the 1950s. Despite the potential significance of this phenomenon in many situations, current design codes still ...

Compressive Strength and Deformation Capacity of Concrete under Sustained Loading and Low Stress Rates

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

This paper investigates the behaviour of concrete failing under high stress levels and subjected to different types of loading. The aim of this investigation is to clarify the development of linear and nonlinear creep strains and how they relate to materia ...

Behaviour of concrete in compression and shear under varying strain rates: from rapid to long-term actions

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

In the present research, the uniaxial compression behaviour of concrete under different strain rates is investigated. The investigation emphasises the influence of the strain rate on the development of inelastic deformations due to nonlinear creep for high ...

Analogy between Sustained Loading and Strain Rate Effects on the Nonlinear Creep Response of Concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

This paper investigates the uniaxial compression behaviour of concrete under different strain rates and its relation to sustained loading. The aim is to observe the strain rate effect on the pre- and post-peak behaviour of concrete. In particular, the deve ...
