Energy and Cost Assessment of Adaptive Structures: Case Studies

Gennaro Senatore

This paper demonstrates how adaptive design (details published elsewhere) can be employed to save, on average, 70% of whole-life energy on a range of spatial structures, the whole-life energy deriving from an embodied part in the material and an operationa ...

Robust model updating methodology for estimating worst-case load capacity of existing bridges

Ian Smith, Didier Vernay, François-Xavier Favre

High-value infrastructure elements, such as bridges, are typically over-designed. Model-updating techniques are useful for estimating the reserve load capacity (beyond safety factors) of bridges and this improves sustainability through good asset-managemen ...

Numerical study on factors that influence the in-plane drift capacity of unreinforced masonry walls

Katrin Beyer, Kiarash Mohtasham Dolatshahi

Displacement‐based assessment procedures require as input reliable estimates of the deformation capacity of all structural elements. For unreinforced masonry (URM) walls, current design codes specify the in‐plane deformation capacity as empirical equations ...

Comparing methodologies for structural identification and fatigue life prediction of a highway bridge

Ian Smith, Alain Nussbaumer, Sai Ganesh Sarvotham Pai

Accurate measurement-data interpretation leads to increased understanding of structural behavior and enhanced asset-management decision making. In this paper, four data-interpretation methodologies, residual minimization, traditional Bayesian model updatin ...

Flat prestressed unbonded retrofit system for strengthening of existing metallic I-Girders

Alain Nussbaumer, Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

In this study, a novel retrofitting system is developed to strengthen existing metallic I-girders using prestressed unbonded carbon fiber reinforced polymer (CFRP) plates. The system relies on a pair of mechanical clamps. Each clamp holds two CFRP plates ( ...

Prestressed CFRP-strengthening and long-term wireless monitoring of an old roadway metallic bridge

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

This paper presents an application of prestressed carbon ﬁber-reinforced polymer (CFRP) plates for the strengthening of metallic girders of a roadway bridge in Melbourne, Australia. The study also describes the application of a wireless sensor network (WSN ...

UHPFRC for the cast-in place reinforcement of offshore maritime signalization structures

Emmanuel Denarié

Offshore lighthouses are a remarkable historical heritage often over 100 years old. The management of their aging is a challenge. The extremely low permeability of Ultra-High- Performance Fiber Reinforced Concretes (UHPFRC), combined with their outstanding ...

Railway bridge damage detection using vehicle-based inertial measurements and apparent profile

Pablo Antolin Sanchez

The presence of damage in a railway bridge alters its stiffness and consequently, its static and dynamic response to loading. The dynamic response of a railway bridge to loading produces a dynamic response in the passing vehicle, potentially enabling detec ...

Experimental validation of a railway bridge made of a reinforced UHPFRC-T-beam

The material UHPFRC is not yet used in the field of bridge construction regularly. The reasons are missing codes and allurements for innovation in the structural engineering. Nevertheless, UHPFRC has many advantages, which are significant compared to the u ...
