Stronger S.r.l. is a Spin-off Company (Small Medium Enterprise) that works as a
link between the Academia and the Industry in Civil and Environmental Engineering.
The Company offers high-profile tools and methodologies that lead to structures
that fulfill required performances under a resilience and sustainability point of
view.
With resilience it is intended the capacity of a system (intended as an aggregate of
interconnected elements such as structures and infrastructures) to resist negative
events (either of natural, accidental or exceptional origin), while at the same time, it
maintains an acceptable level of service and integrity and the capacity to reorganize
in an efficient manner.
With sustainability it is intended the requirement that leads to a rational use of
resources, direction of investments, technological and normative progress, with the
future needs of the society, as well as those current.

ABSTRACT OF THE WORK PROGRAMME

The following technology-specific challenges have to be
addressed
in 2014:
Wind energy: Develop control strategies and innovative
substructure concepts - There is a need for i) control strategies
and systems for new and/or large rotors and wind farms (onand offshore); ii) new innovative substructure concepts,
including floating platforms, to reduce production, installation
and O&M costs for water depths of more than 50m.

Support Applicative
research for the
different purposes

In 2015:
Wind energy: Substantially reduce the costs of wind energy There is a need for innovative integrated dedicated offshore
systems (e.g. with a significant lower mass per unit power
installed) to reduce production, installation and O&M costs for
water depths of more than 50m.

b) Research and innovation actions [2014]
- Develop standardized methods to assess climate change
impacts, vulnerabilities, and risks, and to identify and assess the
performance of adaptation measures (technological and nontechnological options). Methods should focus on long-term
climate change and extreme events for European sectors of
particular socio-economic and environmental significance, paying
due consideration to uncertainty, and encompass indirect, crosssectorial effects and cascade impacts, if relevant.
- Provide state-of-the-art decision support tools tailored to
facilitate decision-making by different end-users (e.g. individuals,
businesses, private sector firms, local authorities, governments),
while developing adaptation plans and measures.

DRS-13-2015: Critical Infrastructure Protection topic 2:
Demonstration activity on …
Comprehensive approach should be developed that take into
account the security issue from the conceptual design of any
building to its operation (in the case of a critical infrastructure) or
use (in the case of households). Cascade failure of
interconnected infrastructure assets (installations for energy,
transport, water, ICT) due to co-location or hub-functions needs
to be avoided. The comparison of different solutions tested
should include cost and cost/benefit analyses, and societal
implications
The proposal shall develop methods and tools for adapting
building and infrastructure standards and design methodologies
(…). Furthermore the research proposal shall demonstrate its
finding, taking into account the occurrence of different types of
natural (climate or geological) hazards, and including
comparative cost and cost/benefit analyses. The topic will
complement Seventh Framework Programme research focusing
on impacts of extreme weather on critical infrastructure.

development of methods for assessing resilience
The proposal shall demonstrate that a set of common and
thoroughly validated indicators, including economic indicators,
could be applied to critical infrastructures in order to assess its
level of “resilience”, moreover a scale approach of “resilience”
level should be proposed across critical infrastructures (energy
grids, transportation, government, nuclear research
infrastructures, water, etc.). The methodology shall be based on
at least four types of critical infrastructure as test cases. Specific
models and modeling approaches will be proposed(..). security
metrics and indicators will be proposed that could be used in the
developed models to quantify to the possible extent the
considered risk and impact as well as give guidance to the
possible mitigation techniques – approaches. New methods of
assessing resilience based upon comprehensive threat,
criticality, and vulnerability assessments are of outmost
importance. Proposals should follow a uniformed comprehensive
and holistic approach at all levels (e.g. EU, country, local) (….) .
