Structures that adapt to loads through large shape changes: design and optimization

Ian Smith, Gennaro Senatore, Arka Prabhata Reksowardojo

The construction industry is a major contributor to the consumption of mined material resources and to the global energy demand. It is thus important to consider energy and material efficiency criteria for the design of civil structures. Through sensing an ...

Experimental testing of a small-scale truss beam that adapts to loads through large shape changes

Ian Smith, Gennaro Senatore, Arka Prabhata Reksowardojo

Adaptive structures can modify their shape and internal forces through sensing and actuation in order to maintain optimal performance under changing actions. Substantial whole-life energy can be saved with respect to traditional passive designs through wel ...

A Comparison of Greedy and Global Searches for Measurement-System Design in Bridge Load Testing

Ian Smith, Numa Joy Bertola

Due to conservative design models and safe construction practices, infrastructure often has significant yet-unknown reserve capacity that greatly exceeds code requirements. Reserve-capacity assessments lead to better asset-management decisions through eith ...

Occupant- detection strategy using footstep-induced floor vibrations

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

Identification of occupant presence and location inside buildings is essential to functional goals such as security, healthcare, and energy management. Floor-vibration measurements, induced by footstep impacts, provide a non-intrusive sensing method for oc ...

Model-based interpretation of floor vibrations for indoor occupant tracking

Ian Smith, Yves Sylvain Gilles Reuland, Slah Drira

Information regarding occupant flows inside buildings is beneficial for applications such as thermal-load control, market research and security enhancement. Existing methodologies for occupant tracking involve data-driven techniques that rely either on rad ...

Element location and classification following a damage event of a near-full-scale deployable tensegrity structure

Ian Smith, Ann Christine Sychterz

Current infrastructure is designed and built such that it must resistall possible loads. This leads to overdesigned structures that are inefficient in terms energy and cost. A structure that can self-identify damage, adapt, and learn for future events resu ...

Damage mitigation of a near-full-scale deployable tensegrity structure through behavior biomimetics

Ian Smith, Ann Christine Sychterz

Current infrastructure is designed and built such that it must simultaneously comply with all possible loads. This leads to overdesigned structures that are inefficient in terms energy and cost. A structure that can self-identify damage, adapt, and learn f ...

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 ...

Measurement-based support for post-earthquake assessment of buildings

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

After a damaging earthquake, assessment of the residual seismic capacity is required for large parts of the building stock. Increased vulnerability of structures together with the threat of immediate aftershocks call for rapid and objective decision making ...
