Using footstep-induced vibrations for occupant detection and recognition in buildings

Ian Smith, Yves Sylvain Gilles Reuland, Sai Ganesh Sarvotham Pai, Slah Drira

Occupant detection and recognition support functional goals such as security, healthcare, and energy management in buildings. Typical sensing approaches, such as smartphones and cameras, undermine the privacy of building occupants and inherently affect the ...

Measurement-supported performance assessment of earthquake-damaged concrete and masonry structures

Yves Sylvain Gilles Reuland

As demonstrated by recent events in Italy, New-Zealand, Haiti, and Nepal, earthquakes continue to pose threats to civil infrastructure, including buildings. For a long time seismic ultimate limit states have not been considered in design codes for regions ...

Reducing the uncertainty on the structural behaviour of existing structures through data interpretation

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

This paper presents a methodology for reducing the uncertainty related to the structural behaviour of an existing building in view of a vulnerability assessment regarding future earthquake actions. Estimating the lateral load resistance is a step towards e ...

Evaluating seismic retrofitting efficiency through ambient vibration tests and analytical models

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Angelo Garofano

Economic and environmental imperatives lead to an ever growing need to extend the service life of the existing building stock without putting the users at risk. In zones prone to moderate seismic hazard, many buildings were built without considering seismi ...

Improving Remaining-Fatigue-Life Evaluation Using Data Interpretation

Ian Smith, Yves Sylvain Gilles Reuland, Romain Pasquier

This paper presents a methodology that improves fatigue-performance evaluations using model-based data interpretation. The accuracy of stress-range values is essential for quantifying fatigue damage. These values are usually predicted using physics-based m ...

A model-based data-interpretation framework for post-earthquake building assessment with scarce measurement data

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

Recent earthquake events throughout the world have once again exposed the vulnerability of buildings with respect to earthquakes. It is unlikely and unsustainable to design and - especially in regions with low-to-moderate seismic hazard – to retrofit all b ...

Application of Association Rules to Determine Building Typological Classes for Seismic Damage Predictions at Regional Scale: The Case Study of Basel

Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Lorenzo Diana

Assessing seismic vulnerability at large scales requires accurate attribution of individual buildings to more general typological classes that are representative of the seismic behavior of the buildings sharing same attributes. One-by-one evaluation of all ...

Determining structural properties of a prestressed concrete bridge through the combination of static and dynamic load testing

Eugen Brühwiler, Numa Joy Bertola, Yves Sylvain Gilles Reuland

Examining structural safety requires hypotheses on several properties of the bridge structure, such as material properties, boundary conditions, and self-weight. The traditional approach relies on conservative assumptions for each structural property, foll ...

Is there a relationship between footstep-impact locations and measured signal characteristics?

Ian Smith, Yves Sylvain Gilles Reuland, Sai Ganesh Sarvotham Pai, Slah Drira

Building utilization can be enhanced by tracking occupants. Non-intrusive tracking of occupants using floor-vibration measurements is beneficial for many smart-building applications such as energy consumption, security enhancement, and care-giving. Also, u ...

Data-Interpretation methodologies for Non-Linear Earthquake Response Predictions of Damaged Structures

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

Seismic exposure of buildings presents difficult engineering challenges. The principles of seismic design involve structures that sustain damage and still protect inhabitants. Precise and accurate knowledge of the residual capacity of damaged structures is ...

Usefulness of ambient-vibration measurements for seismic assessment of existing structures

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

A large number of buildings in regions with low to medium seismic hazard have been designed without considering earthquake actions. Retrofitting of all buildings that fail to meet modern code requirements is economically, technically and environmentally un ...

Structural Resilience through Model-Based Data Interpretation: From Building to City-Scale Post-Seismic Assessment

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Lorenzo Diana

Earthquake-design approaches in regions with low to medium seismic hazard often focus on the protection of inhabitants. Therefore, some structural damage is accepted. In addition, large parts of the building stock have usually been built without considerin ...
