This paper presents the results of an experimental campaign carried out on a full-scale reinforced concrete
frame structure, before and after a seismic retrofit by a damped bracing system incorporating silicone
fluid viscous dissipaters. This experimental enquiry was part of a European Commission-funded Research
Program, named “DISPASS”, developed by the pseudodynamic test method implemented at the ELSA
laboratory of the Joint Research Center – Ispra. The general characteristics of the test structure, the
dissipaters and their assemblage within the protective system are initially described. A special procedure
adopted for the design of damped braces, as well as its application and experimental check to this case
study are then presented. The main test results are finally reported, together with a performance-based
evaluation of the observed response in unprotected and protected conditions.
