Predicting the effect of non-uniform fiber distribution on the tensile response of ultra-high-performance fiber reinforced concrete by magnetic inductance-based finite element analysis

Eugen Brühwiler, Xiujiang Shen

on-uniform fiber distribution can significantly reduce the extension of multiple-cracking and favor crack local-izations in Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) members under tension with important implication on the sought durability. ...

Quantification of influence of monitoring duration on measured traffic action effects on fatigue of RC deck slabs of road bridges

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

The safety of existing bridges may be assessed using data from monitoring. The fatigue damage induced during observation period is extrapolated to the total service duration of a structure, and the reserve capacity is estimated. However, due to the randomn ...

Experimental investigation of a keying joint cast in UHPFRC between precast UHPFRC bridge elements

Eugen Brühwiler, Enrique García, Ngoc Thanh Trinh, Numa Joy Bertola

Ultra High-Performance Fiber-Reinforced Cementitious Composite (UHPFRC) is increasingly popular for new structural designs thanks to its high resistance both in tension and compression. When UHPFRC is complemented with steel reinforcing bars or prestressin ...

Cost-benefit evaluation of a monitoring system for structural identification of existing bridges

Eugen Brühwiler, Numa Joy Bertola, Imane Bayane

The monitoring of existing infrastructure has the potential to improve structural-condition assessment, leading to better asset management. Monitoring data, collected through load testing, help identify unknown model-parameter values, and this model-updati ...

Engineering of Existing Structures: The Need and Place for Non-destructive Evaluation

Eugen Brühwiler, Numa Joy Bertola, Thomas Schumacher

Structural engineers today are still educated mainly to design new structures. This ignores the fact that structures already exist and need to be maintained. Students are thus often ill-equipped to deal with maintenance and preservation of existing structu ...

Short Span UHPFRC Railway Bridge in Switzerland - From Design to Implementation

Eugen Brühwiler, Enrique García, Ngoc Thanh Trinh, Numa Joy Bertola

This paper presents the design and construction of the Aiguillon railway bridge in Switzerland, one of the first railway bridges completely made of Ultra-High-Performance Fiber-Reinforced Cementitious Composite (UHPFRC). The length and width of the trough ...

Von Bettlach nach Grenchen über die restaurierte Brücke Witi – ein junger Baustoff weist den Weg

Eugen Brühwiler

In der Landwirtschafts- und Schutzzone Witi macht eine Informationstafel auf die historische Brücke über den Witibach aufmerksam: «103 Römerbrücke. Diese Brücke, die im Volksmund ‹Römerbrücklein› heisst, geht wohl kaum auf die Zeit ihres Namens zurück. Sie ...

Assessing bridge conditions using visual inspection following a risk-based methodology

Eugen Brühwiler, Numa Joy Bertola

Visual inspection of existing bridges is the main source of information to prioritize mainte- nance. This qualitative examination is thus a critical part of civil infrastructure management. In Switzerland, main inspections are typically made every five yea ...
