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.

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 iron based shape memory alloys (SMA) to be integrated in prestressed construction elements are being developed in co-operation with the National Institute of Material Science (NIMS) in Japan.
Investigations into the application of fibre reinforced polymers (FRPs) for seismic retrofitting of existing structures are being carried out. A test structure has been erected in the Empa Laboratory to study the effect of earthquakes.

Static and dynamic tests in the large testing hall

• Tensile compression bending tests on concrete / steel /polymers /rubber /masonry and gypsum
• Fatigue tests on structural elements made of concrete / steel / polymers /rubber /masonry and gypsum
• Punching shear tests on concrete decks; tests on concrete and steel columns, bridge bearings, anchor head systems and pull-off tests
  

Static and dynamic tests on cable systems and anchorages

• Tensile fatigue and rupture tests
• Load transfer tests on anchor heads
• Low temperature tests of cable systems / anchorage
• Saddle- / Deviation test
  

• In-situ monitoring and load testing of structures for the verification of calculated characteristics.
• Empa develops new methods of retrofitting in cooperation with industrial partners.
  Empa accompanies the development of new amterials and methods from the initial concept to a commercial products.
• Consulting services for specific problems in structural engineering (earthquakes, FRP strengthening and damage claims).
