BIOGRAPHY
|
birth date: 19.11.1958
nationality: Swiss (native from Dussnang, Canton of Thurgau)
Education :
- July 1988 : doctoral degree from the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland with a thesis entitled “Fracture mechanics of dam concrete subjected to quasi-static and seismic loading conditions”
- December 1983 : civil engineering diploma (university degree) from the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland
Professional Experience :
- Since 1st April 1995 : Professor of Structural Engineering at EPFL and Head of the Laboratory of Maintenance, Construction and Safety for Civil Structures (MCS) (often considered being the first chair worldwide devoted exclusively to existing civil structures).
- 1991-94 Project Manager and structural engineer with the Swiss Federal Railways (SBB), Division of Bridges and Structures, Zurich: Monitoring and maintenance of bridges and structures, Project manager and checking engineer for the construction of new bridges and rehabilitation of existing bridges.
- 1989/90 Research associate at the Department of Civil Engineering, University of Colorado, Boulder, USA : Fracture mechanics of concrete and fracture of concrete dams.
- 1986-88 Doctoral student at EPFL-LMC (Building Materials, Prof. Wittmann) : Fracture mechanics of concrete, fracture of concrete dams under seismic loading

MISSION
|
The activities as a Professor at the Swiss Federal Institute of Technology (EPFL) (since 1995) are motivated by the following vision :
“Methods for the examination of existing structures (“Examineering”) must be developed with the ultimate goal to limit construction intervention (and thus the client’s expenditure) to a strict minimum. If interventions are necessary then their objective is to improve the structure (not just to repair it). This goal is in agreement with the principles of sustainable development.”

Activities
|
The basic approach is to bring material and structural engineering sciences together !
A. Research
The ultimate goal is to apply results from scientific research to solve issues related to civil structures. The domains include:
- time dependant reliability and safety of structures including remaining fatigue life, dynamic behaviour and resistance of existing bridges
- measurement and monitoring of structural behaviour and action effects
- non-destructive testing methods
- Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) and high performance steel reinforcement for the improvement of existing and new concrete structures
B. Teaching
Bachelor and Master courses for civil engineering students at EPFL :
- Safety and serviceability of civil structures (BA: 4th semester)
- Aesthetics of civil structures (MA: 8th semester)
- Existing structures I – Safety and durability (MA: 7th semester)
- Existing structures II - Interventions (MA: 8th semester)
- Risk management (MA: 8th semester)
Doctoral School - Program Civil and Environmental Engineering :
- Fracture mechanics and fatigue of structures (CIVIL-702)
- Experimental investigation in structural mechanics (CIVIL-703)
C. Technology Transfer and Consulting
- Examination of existing structures (bridges (reinforced concrete, riveted steel, natural stone masonry) and buildings) and interventions for their improvement
- Structural preservation of structures of high cultural value and evaluation of aesthetics of civil structures
- Professional committees, codes
Achievements :
- Examination and conceptual design of interventions on more than 15 medium and large size bridges and on more than 10 bridges with high cultural value in Switzerland.
- Collaboration within several code writing committees, in particular SIA 269 codes on existing structures (to be released in 2011)
- Publication of the book : Brühwiler, E., Menn, C.: Stahlbetonbrücken (Reinforced Concrete Bridges). Dritte, aktualisierte und erweiterte Auflage, Springer Verlag Wien New York, 2003, 551 S (in German). (Updating and extension of the book „Stahlbetonbrücken“ initially published in 1984 by Prof. Christian Menn (ETH Zurich).
