PROJECTS WITHIN S3T

Comparison of Vibration Control in Civil Engineering using Passive and Active Dampers (COVICOCEPAD)

This project focuses on the assessment of vibration control in tall- and long-span civil engineering structures under dynamic transient or cyclic actions of short or long duration. Specially, the project contributes to the development of analytical and computational techniques for vibration control; characterization of the behaviour of control algorithms and dampers in reference structures; experimental validation on large-scale structures; optimization of vibration control for mitigation of natural hazards.

Material Algorithms, Finite Element Methods, Experiments (MAFESMA)

MAFESMA aims at bridging the gap between extending material knowledge and the design of active machines and structures, focusing on:
• Tools for modelling the functional behaviour of Shape Memory Alloys (SMA) and Magnetically actuated Shape Memory (MSM) alloys
• Controlling the long-term behaviour of SMA/ MSM actuators
• Development and control of SMA-actuated smart structures, especially smart Fibre Reinforced Polymer composite structures.

Micro-Measurement and Monitoring System for Ageing Underground Infrastructures (Underground M3)

One of the greatest challenges facing civil engineers is the stewardship of ageing infrastructures. Underground M3 aims at developing prototype systems for condition assessment and monitoring of ageing underground infrastructures. The project focuses on the development of micro-detection tools using advances in computer vision; micro-monitoring and communication tools using MEMs and wireless communication; and advanced engineering analysis tools. Field trials are conducted in the Prague Metro, the London Underground and Barcelona/Madrid Metros.

Shape Control of Membrane Reflectors (SCMeRe)

With the use of Gossamer structures, made of membranes or thin shells of reflecting materials, ultra large, light-weight telescopes can be envisaged. These can be several orders of magnitude lighter than the current monolithic passive mirrors. SCMeRe addresses the following scientific and technological challenges: nonlinear analysis of piezoelectric membranes subjected to buckling; inverse problem for strain distribution for a given shape error; metrology; active shape control of distributed piezoelectric shells and membranes.

Shape Memory Alloys to Regulate Transient Responses in Civil Engineering (SMARTeR)

Shape Memory Alloys (SMAs) have the potential to be used in structural design as a smart material able to mitigate the effects of transient loading. SMARTeR focuses on methodologies and tools for the optimal design of SMA dampers fitted for applications in civil engineering, i.e., on constitutive laws and material models; numerical tools for simulation and control of structures incorporating SMAs; experiments; and validations on cable-stayed bridges for reducing cable vibrations caused by wind.

Smart Aircraft Morphing Technologies (SMORPH)

Advances in smart structures and active materials during the last decade are likely to yield significant changes in aircraft design through the controlled change of wing shape, referred to as ‘wing morphing’. In SMORPH we investigate critical vehicle and technology issues related to morphing, such as: performance requirements; modelling methodologies; morphing design and optimization. Wind tunnel tests and a remotely piloted vehicle are used for proof-of-concept analysis and validations of morphing concepts.

Smart Sensing for Structural Health Monitoring (S3HM)

S3HM is concerned with predictive maintenance and lifetime extension of civil engineering structures. The specific objective of this project is to combine the most recent developments in sensor and actuator technology, networks, signal processing and computer techniques to explore new avenues in structural health monitoring (SHM). The project addresses the following issues: using smart sensing technologies for SHM; extracting features relevant to damage and immunity to variability; designing robust methods for autonomous SHM systems.
