Hydraulic fracturing (HF) is widely used in the oil and gas industry to enhance production from tight reservoirs. The process involves the injection of fluid at a given flow rate into a wellbore in order to propagate a fracture in rocks and thus increase t ...

The structural solution for cross girder bracings or box girder diaphragms in steel bridges is often made with tubular elements, specially efficient if compression is required for structural behaviour. The connection between the tubular elements and the gi ...

New framework for calibration of partial safety factors for fatigue design

Alain Nussbaumer, Luca D'Angelo

In Eurocode standards, three verification schemes are proposed for fatigue design under variable amplitude loadings: 1) Based on constant amplitude fatigue limit; 2) Based on constant amplitude equivalent stress range at 2.10 cycles; 3) Based on accumulate ...

Size effect on punching shear strength: differences and analogies with shear in one-way slabs

Aurelio Muttoni, Miguel Fernández Ruiz

Size effect has been theoretically and experimentally acknowledged as a phenomenon influencing the shear and punching shear strength of concrete structures, with reducing unitary shear strength for increasing member sizes. For members failing in shear, as ...

When a frictional interface is subject to a localized shear load, it is often (experimentally) observed that local slip events propagate until they arrest naturally before reaching the edge of the interface. We develop a theoretical model based on linear e ...

Shear fatigue of reinforced concrete members without transverse reinforcement has been observed to be potentially governing for the strength of some structural members subjected to large live loads of repetitive nature (as traffic, wind or wave actions). A ...

Fatigue behavior of hybrid GFRP-concrete bridge decks under sagging moment

Haifeng Fan, Yuqing Liu

This paper presents a new cost-effective hybrid GFRP-Concrete deck system that the GFRP panel serves as both tensile reinforcement and stay-in-place form. In order to understand the fatigue behavior of such hybrid deck, fatigue test on a full-scale specime ...

The tensile fatigue behaviour of ultra-high performance fibre reinforced concrete (UHPFRC) under constant amplitude fatigue cycles is presented. Three series of uniaxial tensile fatigue tests up to a maximum of 10 million cycles were conducted with the obj ...

Continuous-fiber ceramic matrix composites (CMCs) are of interest as hot-section components in gas turbine engines due to their refractoriness and low density relative to metallic alloys. In service, CMCs will be subjected to spatially inhomogeneous temper ...

Fatigue Behaviour of Steel Reinforcement Bars at Very High Number of Cycles

Marina Rocha Pinto Portela Nunes

A large portion of reinforced concrete (RC) bridges in the western world were built in the second half of the last century. RC bridge deck slabs are nowadays often subjected to increased traffic loading and volume than originally designed for and thus, ste ...
