Assesing The Level of Performance of Elastomeric Antiseismic Devices for Seismic Isolation at The Base
Main Article Content
The paper presents the study of elastomeric insulation devices for isolating the base, taking into account the multicriteria correlative evaluations between the dominant characteristics of the external dynamic actions and the essential parameters of the isolated structures.In attempt of alleviate the seismic effects of the Earth on buildings, bridges, etc., over the years, a number of technologies and methods for designing structures resistant to seismic actions have been developed. One such method in continuous evolution is the seismic isolation at the base.All practical sistems of isolation must comply with a number of essential requirments, defined by flexibility, amotization and resistance to exploiting stresses, the three elements actually representing performance criteria.The elastomers supports devices must function properly when subjected to normal environmental conditions and maintenance, during uptime are determined by o resonable economical design.The concept of protection at random dynamic actions is based on limiting degradations, damages, and also avoiding collapses of structural elements, nonstructural elements, of equipments and installation in order to comply with imposed performance criteria.
