Re:Crete - A Footbridge made of Reused Concrete Blocks

Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer, Jan Friedrich Georg Brütting, Julie Rachel Devènes

Today, concrete is the most widely used construction material worldwide. Strong, versatile, durable, and vector of economic development, this exceptional material is also the principal cause of greenhouse-gas emissions, material depletion and waste generat ...

Conceptual design of 1000 m scale steel-UHPFRC composite truss arch bridge

Xiujiang Shen, Ping Zhu

Excessive self-weight and difficulty in construction are the main issues confronted by super-long-span arch bridges. To address these issues, a conceptual design of steel-ultra-high performance fibre-reinforced concrete (UHPFRC) composite truss arch bridge ...

Constructional method of UHPC on steel deck of long span suspension bridge and in-situ experimental test

Jian Zhan

The Second Dongting Lake (SDTL) Bridge is the longest steel truss girder suspension bridge in China, which has a main span of 1480 m. To alleviate deterioration issues in the orthotropic steel deck (OSD), the steel-ultra high performance concrete (UHPC) li ...

Static and Fatigue Biaxial Flexural Behavior of Strain-Hardening UHPFRC Thin Slab Elements

Xiujiang Shen

Cast-in-place thin layers of Ultra-High Performance Fiber Reinforced Cementitious Composites (UHPFRC) on the specific zones of existing reinforced concrete (RC) bridge decks has been demonstrated to be a technically efficient and economic rehabilitation an ...

EPFL2020

This work presents force and shape control strategies for adaptive structures subjected to quasi-static loading. The adaptive structures are designed using an integrated structure-control optimization method developed in previous work, which produces minim ...

2020

Constructed in 1969, the Chillon viaducts constitute a vital component of the Swiss roadway network. The bridge deck was strengthened in 2015 by means of an Ultra High Performance Fiber Reinforced Cement-based Composite for alleviating the effects of deter ...

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

Eugen Brühwiler, Imane Bayane, Amol Mankar

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 ...

Probabilistic reliability framework for assessment of concrete fatigue of existing RC bridge deck slabs using data from monitoring

Eugen Brühwiler, Imane Bayane, Amol Mankar

Assessment of existing bridge structures for inherent safety level or for lifetime extension purposes is often more challenging than designing new ones. With increasing magnitude and frequency of axle loads, reinforced concrete bridge decks are susceptible ...

Bridge Decks in High Strength Steel and Fatigue Design

Mouaad Souadi

Les ponts mixtes ont été largement utilisés en raison de leurs avantages économiques, constructifs et structuraux. Par ailleurs, le marché de la construction commence à tendre vers l’utilisation d’acier à haute résistance HSS. Ce genre d’acier séduit par s ...
