Measurement system design for civil infrastructure using expected utility

For system identification, most sensor-placement strategies are based on the minimization of the model-parameter uncertainty. However, reducing the uncertainty in remaining-life prognosis of structures is often more relevant. This paper proposes an optimiz ...

Joint Friction during Deployment of a Near-Full-Scale Tensegrity Footbridge

Ian Smith, Sai Ganesh Sarvotham Pai

Most deployable structures, such as operable roofs and masts, move over one degree of freedom. This paper describes a structure that involves loosely coupled movement over several degrees of freedom. Analysis models of these structures are typically inaccu ...

Studies of Sensor Data Interpretation for Asset Management of the Built Environment

Sensing in the built environment has the potential to reduce asset management expenditure and contribute to extending useful service life. In the built environment, measurements are usually performed indirectly; effects are measured remote from their cause ...

Active control for mid-span connection of a deployable tensegrity footbridge

Tensegrity structures are spatial self-stressed pin jointed structures where compression components (struts) are surrounded by tension elements. This paper describes a near full-scale deployable tensegrity footbridge that deploys from both sides and connec ...

Iterative structural identification framework for evaluation of existing structures

Evaluation of aging infrastructure has been a world-wide concern for decades due to its economic, ecological and societal importance. Existing structures usually have large amounts of unknown reserve capacity that may be evaluated though structural identif ...

Measurement, Data Interpretation, and Uncertainty Propagation for Fatigue Assessments of Structures

Ian Smith, Claire Acevedo, Alain Nussbaumer, Romain Pasquier, James-Alexandre Goulet, Luca D'Angelo

Real behavior of existing structures is usually associated with large uncertainty that is often covered by the use of conservative models and code practices for the evaluation of remaining fatigue lives. In order to make better decisions related to retrofi ...

An electric network for evaluating monitoring strategies intended for hydraullic pressurized networks

Ian Smith, Gaudenz Moser

This paper presents a study of similarities between electrical and hydraulic pressurized networks. The primary objective is to examine whether or not it is possible to use electrical laboratory networks measuring voltage to study leak-region detection stra ...
