Testing of Elastomeric Bearings for Bridges

The aim of these testings was to determine mechanical characteristics of elastomeric bearings for new Jankomir bridge over Sava river in Zagreb with emphasis on the characteristics in horizontal direction under vertical load. Tested bearings were roun shaped with diameter of 450 mm and total height of 111 mm type V2ES 2400/190 (thickness of elastomeric layers is 5x11=55 mm, and thickness of steel plates is 4x4+2x20=56 mm ). The manufacturer of these bearings is Polirol Zagreb. Testing was carried out in accordance with european norm prEN 1998-2: ''Bridges with seismic isolation''. Testing were carried out in the Structure testing laboratory of Civil engineering Faculty, University of Zagreb
