Abstract

Two parameters analysis of post-peak dynamic behaviour of high performance concrete 11 i S. Cangiano , R. Cucitore , G.A. Plizzari *C. T. G. - Italcementi Group, Italy * Brescia University, Italy Abstract As well known the seismic performance of reinforced concrete structures is strongly influenced by structural design and by dynamic behaviour of the adopted construction materials. In particular in reinforced concrete frames the contribution of concrete matrix to dissipative phenomena during oligo-cyclic loading, such as seismic events, may play a very important role in the case of steel fibre reinforcement. On the other hand the dynamic properties of steel fibre reinforced concrete (SFRC) are influenced by concrete matrix and by type, geometry and content of fibres. In this work by means of direct and cyclic tensile tests on notched cylindrical specimens is shown the essential contribution of high performance cementitious matrix to post-peak b
