Uncertainty corrrelation in structural performance assessment

Ian Smith, James-Alexandre Goulet

2011

Extended Uniform Distribution Accounting for Uncertainty of Uncertainty

Ian Smith, James-Alexandre Goulet

Increasingly, uncertainties are explicitly considered for important engineering tasks. Often, little case-specific information is available for characterizing these uncertainties. Uniform distributions are an easy way to describe errors in absence of more ...

ASCE2011

Preventing over-instrumentation during the design of a monitoring system for static load tests

Ian Smith, James-Alexandre Goulet

2011

Effects of service loading on the behaviour of a suspension bridge

Ian Smith, Irwanda Laory, Ngoc Thanh Trinh

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 ...

Analysis of clustered tensegrity structures using a modified dynamic relaxation algorithm

Ian Smith, Landolf-Giosef-Anastasios Rhode-Barbarigos, Nizar Bel Hadj Ali

Tensegrities are spatial, reticulated and lightweight structures that are increasingly investigated as structural solutions for active and deployable structures. Tensegrity systems are composed only of axially loaded elements and this provides opportunitie ...

Deployment of a Pentagonal Hollow-Rope Tensegrity Module

Ian Smith, Landolf-Giosef-Anastasios Rhode-Barbarigos, René Motro, Nizar Bel Hadj Ali

Tensegrity structures are spatial reticulated structures composed of cables and struts. Tensegrity systems are good candidates for adaptive and deployable structures and thus have applications in various engineering fields. A “hollow-rope” tensegrity syste ...

Overcoming the limitations of traditional model-updating approaches

Ian Smith, James-Alexandre Goulet

Model updating is useful for improving structural performance assessments. This paper examines an important assumption of traditional model-updating approaches. This assumption requires the error independence between points where predictions and measuremen ...

Anomaly Detection without Structural Behavior Models

Ian Smith

2011

Designing measurement systems for continuous monitoring of structures

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

A good measurement system improves capability to identify the behavior of civil engineering structures. This paper presents a measurement-system design approach for continuous monitoring of structures. This approach performs two tasks: (1) determining the ...

Evaluating two model-free data interpretation methods for measurements that are influenced by temperature

Ian Smith, Irwanda Laory, Ngoc Thanh Trinh

Interpreting measurement data to extract meaningful information for damage detection is a challenge for continuous monitoring of structures. This paper presents an evaluation of two model-free data interpretation methods: moving principal component analysi ...

Performance of two model-free data interpretation methods for continuous monitoring of structures under environmental variations

Ian Smith, Irwanda Laory, Ngoc Thanh Trinh

Interpreting measurement data from continuous monitoring of civil structures for structural health monitoring (SHM) is a challenging task. This task is even more difficult when measurement data are influenced by environmental variations, such as temperatur ...

Measurement system design for damage detection using model-free data interpretation methods

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

Designing a measurement system is usually performed using only engineering judgment and experience. Thus, it may result in either a large amount of redundant data or insufficient data leading to ambiguous results. This paper presents a systematic approach ...

Determining Control Strategies for Damage Tolerance of an Active Tensegrity Structure

Ian Smith, Nizar Bel Hadj Ali, Sinan Korkmaz

Tensegrity structures are spatial, reticulate and lightweight systems composed of struts and cables. Stability is provided by a self-stress state between tensioned and compressed elements. Tensegrities have received interest among scientists and engineers ...

Elsevier2011

Dynamic behavior and vibration control of a tensegrity structure

Ian Smith, Nizar Bel Hadj Ali

Tensegrities are lightweight space reticulated structures composed of cables and struts. Stability is provided by the self-stress state between tensioned and compressed elements. Tensegrity systems have in general low structural damping, leading to challen ...

Elsevier2010

Structural identification through continuous monitoring: data cleansing using temperature variations

Ian Smith, Irwanda Laory

The aim of structural performance monitoring is to infer the state of a structure from measurements and thereby support decisions related to structural management. Complex structures may be equipped with hundreds of sensors that measure quantities such as ...

Design of tensegrity structures using parametric analysis and stochastic search

Ian Smith, Landolf-Giosef-Anastasios Rhode-Barbarigos, Himanshu Jain

Tensegrity structures are lightweight structures composed of cables in tension and struts in compression. Since tensegrity systems exhibit geometrically nonlinear behavior, finding optimal structural designs is difficult. This paper focuses on the use of s ...

Self-Repair of a Tensegrity Pedestrian Bridge through Grouped Actuation

Ian Smith, Nizar Bel Hadj Ali, Sinan Korkmaz

University of Nottingham Press2010

Multimodel Structural Performance Monitoring

Ian Smith, James-Alexandre Goulet

Measurements from load tests may lead to numerical models that better reflect structural behavior. This kind of system identification is not straightforward due to important uncertainties in measurement and models. Moreover, since system identification is ...

Comparison of Two Active Control Strategies on a Tensegrity Structure

Ian Smith, Nizar Bel Hadj Ali, Sinan Korkmaz

2010

Design optimization and dynamic analysis of a tensegrity-based footbridge

Ian Smith, Landolf-Giosef-Anastasios Rhode-Barbarigos, Nizar Bel Hadj Ali, Alberto Pascual Albi

Tensegrity structures are spatial structural systems composed of struts and cables with pin-jointed connections. Their stability is provided by the self-stress state in tensioned and compressed members. Although much progress has been made in advancing res ...
