Enhanced safety with post-installed shear reinforcement

The safety of existing concrete slabs against shear may be insufficient for several reasons such as design and construction errors, structural modifications or increased loads. Moreover, the knowledge about shear design has significantly increased over the ...

Development and Utilization of Structural Component Databases for Performance-Based Earthquake Engineering

Dimitrios Lignos

Abstract Performance-based earthquake engineering necessitates the development of reliable nonlinear analysis models that are able to simulate the behavior of structures from the onset of damage through collapse. These models provide engineering demand par ...

Plastic hinge models for the displacement-based assessment of wall-type bridge piers with poor detailing

Katrin Beyer, Pia Hannewald

This paper presents a plastic hinge modelling approach for wall-type bridge piers with detailing deficiencies such as low transverse reinforcement ratios and lap splices in potential plastic hinge regions. Currently available plastic hinge length estimates ...

Numerical modelling and experimental investigation on welding residual stresses in large-scale tubular K-joints

Alain Nussbaumer, Jean-Marie Drezet, Claire Acevedo

This paper is devoted to the experimental and numerical assessment of residual stresses created by welding in the region surrounding the weld toe of tubular K-shaped joints (i.e. region most sensitive to fatigue cracking). Neutron-diffraction measurements ...

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 ...

Fatigue strengthening of damaged metallic beams using prestressed unbonded and bonded CFRP plates

Matteo Galli, Masoud Motavalli, Andrin Herwig, Elyas Ghafoori

Bonded fiber reinforced polymers (FRPs) reinforcement systems have traditionally been found to be an efficient method for improving the lifespan of fatigued metallic structures and have attracted much research attention. Nevertheless, the performance of a ...

Dynamic performance comparison between buckling-restrained braced frames with concentric and eccentric configurations

Gary Scott Prinz

Buckling-restrained braced frames (BRBFs) are often used in steel buildings to resist seismic loads; however, BRBF ductility can be limited by poor performance of the beam-column-gusset regions. Additionally, the concentric brace configuration in BRBFs can ...

A method for the geotechnical design of heat exchanger piles

Lyesse Laloui, Hervé Péron, Christoph Knellwolf

There is currently a lack of established calculation method for the geotechnical design of heat exchanger piles. Thermo-mechanical effects are ignored and large overall security factors are therefore applied. This paper presents a new geotechnical numerica ...

New Fe-immobilized natural bentonite plate used as photo-Fenton catalyst for organic pollutant degradation

César Pulgarin

Novel photo-Fenton catalysts were prepared by immobilizing iron species on commercial bentonite plates via two methods: (1) ion exchange reaction (Fe3+ vs. Na+) by aqueous suspension powder-clay/FeCl3 followed by plate preparation, and (2) forced hydrolysi ...

In-situ testing of a heat exchanger pile

Lyesse Laloui

The behavior of a pile subjected to thermo-mechanical loadings was studied in situ with the aim of quantifying the thermal influence on the bearing capacity of heat exchanger piles. A pile situated in a building under construction was equipped with a chann ...
