Problems to be solved
Earthquake protection of buildings is of key importance. Retrofitting of a large amount of structures, not respecting the new regulations is becoming an important market. The traditional methods require important additional strengthening inducing works at high costs. Dissemination of energy dissipation devices is also limited. The objective is to overcome the limits of energy dissipation devices through coupling of a series of dampers and cables. Some promising preliminary studies have already been carried out.
Scientific objectives and approach
The technical key problem concerns the connections between the cable and the structure to be protected. Moreover, the following items must be addressed: architectural constraints, end-user needs, and public authorities approval aspects. The project includes the development of prototypes and tests on full-scale mock-ups, full-scale mock-ups.). Laboratory tests and preliminary studies carried out by the damper manufacturer have shown the feasibility of the damper/cable system (DCS). The ambition is to limit the number of dampers needed to protect the structure against earthquakes. Identification of the requested DCS characteristics and the structural typologies for which the system is applicable. Design of the DCS components, and supply of DCS prototypes. Study of architectural issues related to the installation of DCS. Experimental analysis of the DCS prototypes and of full-scale structures equipped with them. Evaluation of the technical and economical benefits of the use of such devices. Design guidelines for the implementation of the semi-active and passive control technologies.
The industrial results of this project - prototype innovative devices - for earthquake protection of structures at low costs, will contribute to the increase of European retrofitting market world-wide. In collaboration with construction companies, effective and economic solutions for the retrofitting of schools and hospitals will be proposed.
