Seismic-Resistant Highly Deformable Structures SHDS

Details

Seismic-Resistant Highly Deformable Structures (SHDS) is a research project funded by H2020 trough the Marie Slodovska Curie Programme.
The recent earthquakes that have struck Europe the last decade, L'Aquila (2009) and Lorca (2011) (see picture on the left) have shown that even for a moderate seismic hazard level the seismic action can cause huge personal and economic losses. Therefore there is a need for new structural designs based on the performance of the structures during earthquakes rather than their strength. 
This project will focus on the development and verification of a novel seismic-resistant highly deformable reinforced concrete structure. This innovative design takes advantage of the superior deformability of reinforced High Deformability Concrete (HDC) elements to develop a structure with controlled performance, in which the structural damage is concentrated in especially designed elements.
The new structural system combines ductile shear walls with flexible coupling beams designed with reinforced HDC. HDC is currently being developed as part of Anagennisi, a FP7 EU funded project, and utilises recycled rubber particles as replacement of both fines and coarse aggregates.
