Structural Engineering Research Lab

We do research for a higher level of safety and security in civil engineering structures. Through the application of modern materials and technologies, new solutions in vibration mitigation, structural health monitoring and earthquake retrofitting will be acquired.

An electric current passed through two Fe-SMA strips to strengthen a concrete beam, heating them to 160° C and cooling down to room temperature to prestress the Fe-SMA strips.
Research priorities

Structural Dynamics and Adaptive Structures
A major part of the EU-FP6 Project "Sustainable Bridges" concerns the development of a wireless communication network. In the future, this sensor network will be used for structural health monitoring.
The Empa Bridge, a composite material cable-stay pedestrian bridge erected in the Empa test laboratory, will be equipped with sensors and actuators. Methods for vibration damping through the application of "Rheological Materials" or "Tuned Mass Dampers" are being researched using this bridge.

Application of Advanced Materials in Construction
New materials for civil engineering structures are developed and investigated in small and large-scale size to show its feasibility also in for the building industry realistic structures. For example carbon fiber reinforced polymer or shape memory alloys for the strengthening of reinforced concrete structures are examined in the structural engineering research laboratory.

 

Academic knowledge transfer: Prof. Dr. Masoud Motavalli is teaching at ETH Zürich and at the University of Tehran, Iran, the course "Fibre Composite Materials in Structural Engineering".

The lab is also involved in the international Marie Curie Initial Training Network "endure" and the Cost Action TU 1207 "Next Generation Design Guidlines for Composites in Construciton".
