Influence of model uncertainty and long term deformations in action effects calculation in reinforced concrete structures

Most codes of practice adopt a semi probabilistic design approach for the dimensioning and assessment of structures. Accordingly, structural safety is ensured by performing limit state verifications using design values determined with adequately calibrated ...

Application of micro X-ray diffraction to investigate the reaction products formed by the alkali–silica reaction in concrete structures

Gervais Chapuis, Philip Pattison, Alla Arakcheeva

Alkali-silica reaction (ASR) is one of the most important deterioration mechanisms in concrete leading to substantial damages of structures worldwide. Synchrotron-based micro-X-ray diffraction (micro-XRD) was employed to characterize the mineral phases for ...

Stress 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)

Jaime Mata Falcon, Aurelio Muttoni, Miguel Fernández Ruiz

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 ...

Processing of Sustainable Cellular Biocomposites

Carole Boissard

Petroleum-based polymers and composites are commonly used in a wide variety of application fields. However ecological concerns, increasing oil prices and dwindling natural resources explain why nowadays industrial and public interest is more than ever focu ...

Influence de la précontrainte sur la résistance au poinçonnement de dalles en béton armé

Thibault Clément

Flat slabs are commonly used in Switzerland but also in north America and in many European countries. Slab bridges are also a typical solution for crossing of motorways for example. In both cases, supporting a slab by columns is justified by the simplicity ...

Cementitious matrices for high performance fibre reinforced cement composites (HPFRCC), in particular ultra-high performance fibre reinforced concretes (UHPFRC)

Emmanuel Denarié

A cementitious matrix for Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) containing the following constituents (in % mass of dry mix): a) 25 to 65 % Portland cement type CEM I; b) 25 to 70 % of Limestone filler; c) 5 to 15 % ultrafine mineral ad ...

The origin of early age expansions induced in cementitious materials containing shrinkage reducing admixtures

Karen Scrivener

Studies on the early-age shrinkage behavior of cement pastes, mortars, and concretes containing shrinkage reducing admixtures (SRAs) have indicated these mixtures frequently exhibit an expansion shortly after setting. While the magnitude of the expansion h ...

Application des réseaux de Bragg à la détermination des déformations distribuées dans les matériaux composites

The behaviour of brittle matrix fibre reinforced-composites is dependent of the properties of its constituents (fibre, matrix and fibre-matrix interface) and is affected by the mechanical and environmental loads. The fracture of a unidirectional composite ...

Direct load transmission in hybrid FRP and lightweight concrete sandwich bridge deck

Thomas Keller, Till Vallée, Erika Schaumann

Direct load transmission experiments on hybrid short-span beam specimens for a novel bridge deck were performed. The sandwich construction consists of three layers: a fiber- reinforced polymer composite (FRP) sheet with T-upstands for the bottom skin, ligh ...

Shear strength of URM walls retrofitted using FRP

Pierino Lestuzzi, Marc Badoux, Mohamed Elgawady

This paper compares different models currently used to calculate the shear strength of unreinforced masonry (URM) walls retrofitted using fiber reinforced polymers (URM-FRP). The shear strengths of six recently tested URM-FRP walls were compared to shear s ...

Processing of homogeneous ceramic/polymer blends for bioresorbable composites

Jan-Anders Edvin Maansson, Pierre-Etienne Bourban

Three methods to mix ceramic fillers, hydroxyapatite or β-tricalcium phosphate, with a polymer matrix, a poly l-lactic acid, are investigated as a first step prior to supercritical foaming to prepare porous composite structures for biomedical applications. ...

Composite action of FRP bridge decks adhesively bonded to steel main girders

Herbert Gürtler

Up until today reinforced concrete has been used in most cases for the manufacturing of bridge decks. Depending on the quality of the work carried out, defects can already occur after only a few years. These defects mostly appear in the form of corrosion o ...

Tensile fatigue performance of pultruded glass fiber reinforced polymer profiles

Thomas Keller

Axial tension-tension fatigue experiments were performed on pultruded glass fiber reinforced polymer (GFRP) plates in a laboratory environment. Different full-scale specimen shapes were examined: plate strips as-delivered, plate strips with tabs and plates ...
