Low-tech methods for the reuse of reinforced concrete structural elements

Nicole Widmer, Corentin Jean Dominique Fivet, Maléna Bastien Masse, Julie Rachel Devènes

Most of existing buildings are made of concrete, new buildings are being built with it and others are demolished when still in good structural condition. This drives increased demands for raw materials, greenhouse gas emissions, and an accumulation of demo ...

Experimental Study on the Static and Fatigue Behaviour of a New Mechanical Wedge-Barrel Anchor

Alain Nussbaumer

Post-tensioned steel strands have been traditionally used in different prestressed structures such as concrete girders, post-tensioned concrete slabs, cable-stayed bridges, post-tensioned walls, etc. for a long time. However, due to the vulnerability of st ...

Quantiﬁcation of traﬃc and temperature eﬀects on the fatigue safety of a reinforced-concrete bridge deck based on monitoring data

Amol Mankar, Eugen Brühwiler, Imane Bayane

For assessment of existing reinforced-concrete bridges, only few rules and recommendations are available, and engineers meanwhile apply design codes for new bridges to evaluate the fatigue safety of existing bridges leading to non-realistic approaches and ...

Next generation synthetic fibers UHPFRC for sustainable structural applications

Amir Hajiesmaeili

The ever-increasing demand for rehabilitation of existing structures and construction of new ones, along with environmental issues of the construction sites represent a heavy burden for society in terms of economy and environment. Meanwhile, Ultra-High Per ...

Structural performance of complex core systems for FRP-balsa composite sandwich bridge decks

Michael Osei-Antwi

Based on current fiber-reinforced polymer (FRP) composite construction principles, FRP decks fall into two categories: pultruded decks and sandwich decks. Sandwich decks comprise face sheets and either honeycombs or foams reinforced with internal FRP webs ...

GFRP-balsa sandwich bridge deck: Concept, design and experimental validation

Thomas Keller, Julia De Castro San Roman Fest, Michael Osei-Antwi

The concept, design and experimental validation of the new Avançon Bridge in Bex, Switzerland, are described. The lightweight glass fiber-reinforced polymer (GFRP) sandwich bridge deck adhesively bonded to steel girders reduced the traffic disruption perio ...

FRP-balsa composite sandwich bridge deck with complex core configuration

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Michael Osei-Antwi

The aim of this work was to investigate to what extent the performance of a glass fiberreinforced polymer (GFRP) sandwich slab-bridge with uniform high-density balsa core could be improved in terms of structural efficiency and weight thanks to a more compl ...

Hybrid FRP-lightweight concrete sandwich system for engineering structures

Erika Schaumann

Hybrid slab systems combining fiber-reinforced polymer (FRP) composites with concrete are promising load-bearing structures, and an increasing number of applications has demonstrated their high potential in terms of structural performance and durability. H ...

Analytical modeling of the pre- and post-yield behaviour of bond in reinforced concrete

Aurelio Muttoni, Miguel Fernández Ruiz

This paper presents the theoretical basis and the main results of an analytical model that describes the pre– and post–yield response of bond in reinforced concrete, as well as its influence on the behavior of structural members. The model is based on a nu ...

Long-term compression performance of a pultruded GFRP element exposed to concrete pore water solution

Thomas Keller, Florian Riebel

A durability study was performed on a pultruded glass fiber reinforced polymer (GFRP) compression element of a hybrid GFRP/steel joint for concrete structures. GFRP elements were immersed in alkaline pore water solutions of different temperatures during 18 ...
