000010829 520__ $$2eng$$aIn Italy many precast industrial buildings built between 1950s and 1970s are characterised by beam – column connections based on concrete-neoprene friction strength. Numerical studies recently performed by the authors confirm that, in order to determine the seismic vulnerability of such structures, a reliable value of the neoprene-concrete friction coefficient must be known. Technical bibliography provides many and different values of this coefficient; consequently, in order to define a reliable value, a specific experimental campaign is carried out. Three typologies of experimental tests are performed: tests on neoprene hardness, tilting tests and pulling tests, where the specimen is also axially loaded. In this paper set - up, methodology and results of such tests are accurately described. The tilting tests provide a value of the mean friction coefficient equal to about 0.5. The tests with axial strain underline a dependence of the slip strength by axial load and, in particular, a decrement of the friction coefficient as the axial load increases.
