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

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

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 ...

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

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

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 ...

Methodologies for predicting natural frequency variation of a suspension bridge

Ian Smith, Ngoc Thanh Trinh, Irwanda Laory

In vibration-based structural health monitoring, changes in the natural frequency of a structure are used to identify changes in the structural conditions due to damage and deterioration. However, natural frequency values also vary with changes in environm ...

Combined Model-Free Data-Interpretation Methodologies for Damage Detection during Continuous Monitoring of Structures

Ian Smith, Ngoc Thanh Trinh, Irwanda Laory, Daniele Posenato

Despite the recent advances in sensor technologies and data-acquisition systems, interpreting measurement data for structural monitoring remains a challenge. Furthermore, because of the complexity of the structures, materials used, and uncertain environmen ...

A model-free data-interpretation approach for long-term monitoring of bridges

Ian Smith, Ngoc Thanh Trinh, Irwanda Laory

This paper presents a new model-free data-interpretation approach for damage detection of bridges using long-term monitoring data. The approach combines two model-free methods: Moving Principal Component Analysis (MPCA) and Robust Regression Analysis (RRA) ...

A Hybrid Model-Free Data-Interpretation Approach For Damage Detection During Continuous Civil-Infrastructure Monitoring

Ian Smith, Ngoc Thanh Trinh, Irwanda Laory

A hard challenge associated with infrastructure monitoring is to extract useful information from large amounts of measurement data in order to detect changes in structures. This paper presents a hybrid model-free approach that combines two model-free metho ...

An improved substructural identification strategy for large structural systems

Ngoc Thanh Trinh

To identify physical parameters of a large structural system, the computational challenges in dealing with a large number of unknowns are formidable. A divide-and-conquer approach is often required to partition the structural system into many substructures ...

Measurement System Configuration for Damage Identification of Continuously Monitored Structures

Ian Smith, Nizar Bel Hadj Ali, Ngoc Thanh Trinh, Irwanda Laory

Measurement system configuration is an important task in structural health monitoring in that decisions influence the performance of monitoring systems. This task is generally performed using only engineering judgment and experience. Such approach may resu ...

Effects of service loading on the behaviour of a suspension bridge

Ian Smith, Ngoc Thanh Trinh, Irwanda Laory

In order to achieve reliable information about deterioration, it is important to differentiate between changes in structural behaviour due to service loading (temperature, wind and traffic) and changes resulting from damage when interpreting measurement da ...
