5. Research and development

StroNGER starts as an academic spin off and the Research and Development has an

important role. Stronger is active in collaborations as a SME partner in joint

research proposals.

A presentation that describes StroNGER and its expertise for Horizon 2020 calls is

downloadable at http://www.slideshare.net/StroNGER2012

The main topics are:

• Resilience assessment – Multihazard approach. StroNGER is developing methods

and quantitative indices for the assesment of the resilience of urban areas, also in

case of multiple actions as fire after an earthquake.

• Sustainability and Energy Harvesting. StroNGER is working on methodologies and

tools for harvesting energy from the vibrations of civil structures and

infrastructures.
