Effects of core air gaps and steel inserts on thermomechanical response of GFRP-balsa sandwich panels subjected to fire

Thomas Keller, Anastasios Vassilopoulos, Niloufar Vahedi

Composite sandwich panels composed of a balsa core and glass fiber-reinforced polymer (GFRP) face sheets may offer attractive applications for building slabs and bridge decks. Such composite panels may contain air-filled gaps (caused by initial defects or ...

The influence of wood surface treatments with different biomolecules on dry and wet strength of linear friction welded joints

Yves Weinand

The moisture resistance of friction-welded wood joints can be improved by applying bio-based bonding additives. Several biomolecules including tannic acid, organosolv lignin from hardwood, kraft lignin from softwood, and derivates thereof, were investigate ...

Constrained Form-Finding of Tension-Compression Structures using Automatic Differentiation

Stefana Parascho

This paper proposes a computational approach to form-find pin-jointed bar structures subjected to combinations of tension and compression forces. The generated equilibrium states can meet structural and geometrical constraints via gradient-based optimizati ...

Out-of-plane permeability measurement for reinforcement textiles: A benchmark exercise

Véronique Michaud, Baris Çaglar, Amaël Maximilien Cohades, Damiano Salvatori

The out-of-plane permeability of two glass fibre fabrics was measured by 26 institutions using silicone oil as a test fluid. Participants in this study were free to select the test procedure, specimen dimensions and data analysis method, provided that test ...

Experimental and numerical investigation of the thermo-mechanical behaviour of an energy sheet pile wall

Lyesse Laloui, Alessandro Francesco Rotta Loria

One-of-a-kind experimental and numerical investigation is provided in this paper about energy sheet pile walls: earth retaining structures that embed heat exchanger probes within piles for the exploitation of shallow geothermal energy. The study resorts to ...

Consistency in Solving the Inverse Problem of the Voce-Chaboche Constitutive Model for Plastic Straining

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa

This paper focuses on an inverse problem involving a commonly used material model in structural steel applications—the Voce-Chaboche model. In particular, the paper proposes an approach focused on obtaining a consistent set of material parameters that accu ...

Numerical evaluation of test setups for determining the shear strength of masonry

Katrin Beyer, Nicolas Richart, Shenghan Zhang, Lyne Desharnais

The bond shear strength between masonry units and mortar is the weakest link in a masonry wall. Different material tests have been developed in order to characterize this bond behaviour. The objective of this study is to evaluate three common test setups t ...

Stress-state manipulation in fused silica via femtosecond laser irradiation

Yves Bellouard, Philippe Gillet, Benjamin Wesley Mc Millen, Charles Michel Henri Pépin

Controlling the stress in glass after laser exposure is of prime importance not only for photonics applications, but also for preserving the mechanical integrity of glass components in general. The sub-surface exposure of fused silica to femtosecond laser ...

Experimental investigation and modelling of the structural behaviour of confined grouted interfaces for a new steel–concrete connection

Jean-Paul Lebet, Dimitrios Papastergiou

Confined interfaces between cement grout and other materials such as embossed steel or rough concrete are formed in an innovative new steel-concrete connection for composite bridges. This article presents the experimental study of such interfaces and inves ...

Influence of boundary conditions and size effect on the drift capacity of URM walls

Katrin Beyer, Sarah Petry

In codes the drift capacity of unreinforced masonry (URM) walls is often estimated as a function of the failure mode and the aspect ratio. The empirical relationships are based on results from quasi-static cyclic tests on single URM walls, which were teste ...

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 ...

Characterisation of Low Impact Energy Induced Damage in Composite Plates with Embedded Optical Sensors

Jeannot Frieden

Fibre reinforced materials are increasingly employed in aerospace, naval and civil structures because of their low weight and high specific strength and stiffness. A major concern is the inherent susceptibility of composite laminates to barely visible dama ...

A multi-scale multi-physics model of soil drying

Lyesse Laloui, Hervé Péron

Drying shrinkage is modeled at a microscale as a two-stage process of deformation and evacuation of a two-tube vessel system, based on porosimetry evolution. In the first stage water flow is driven by an external evaporation flux. Flow is associated with a ...
