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 programs as Horizon 2020 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.

Villa SilinVilla Silin

Design of an innovative support panel for the restoration of the Villa Silin mosaic

Framework

Damage assessment

Design requirements

• the intervention should be less invasive as possible;

• it should be reversible over time;

• it should make use of natural sustainable materials;

• it should maintain the structural characteristics of the

pavement;

• it has to guarantee adequate structural performance;

• the compatibility of the new materials with the residual

concrete which is in direct contact with the mosaic tiles has

to be assured.

Basis of the Design

In order to take into account the natural environment of the villa, which is characterized by high temperature and humidity changes, the strategy of the project has been oriented toward techniques that can avoid deformation of the supports, something that produce cracks on the screed and consequently damage to the mosaics.

•inclusion of fibers with a good tensile behavior in the

mortar/cement mix that could avoid the development of the

initial micro-cracks;

•use of natural fiber grids to avoid the use of metallic

reinforcements;

•use of mortars/conglomerates with near-zero shrinkage.

Scheme of the flexural test

Flexural tests have been carried out on 8 plate specimens with different mixes

They have been considered as simply supported and they have been loaded at the mid span with an increasing load.

Three sensors have recorded the vertical deflection of the plate with the increasing of the load.
