Precast R.C. columns under cyclic loading : An experimental programme oriented to EC8

The paper gives a complete report on cyclic tests made on precast r.e. columns at ELSA - European Laboratory for Structural Assessment at Ispra (Safety Technology Institute - Joint Research Centre of European Commission) A detailed description of testing provisions is given, together with the design criteria of specimens, which follow EC8 - Eurocode 8 application rules The large set of results obtained from tests is represented by means of tabulated data and graphics in terms of force/displacement cycles, strain histories of materials, curvature distribution of sections and progressive dissipated energy. Seismic performance of tested elements is finally qualified on the base of some critical parameters.
