COMPRESSION TESTS ON RUBBER BRIDGE BEARINGS

THE RESULTS OF COMPRESSION TESTS ARE DISCUSSED THAT WERE CARRIED OUT ON A SERIES OF RUBBER BRIDGE BEARINGS OF VARIOUS TYPES. THE BEARINGS WERE TO BE INCORPORATED IN A BRIDGE DECK, CONTAINING A SEVERE SKEW, UPON WHICH ABNORMAL LOADS WERE TO BE IMPOSED. THE LOAD COMPRESSION CHARACTERISTICS AS DETERMINED WERE TO BE EMPLOYED AS A REFERENCE IN ORDER TO RELATE DEFLECTION MEASUREMENTS IN THE COMPLETED STRUCTURE TO ACTUAL LOAD VALUES. HENCE THE TRUE LOAD DISTRIBUTION IN THE BRIDGE DECK COULD BE COMPARED WITH VALUES OBTAINED FROM A THEORETICAL ANALYSIS OF SKEW SLABS. TESTS WERE FIRST CARRIED OUT WITH THE BEARINGS PLACED BETWEEN STEEL PLATES. SLIPPING OCCURRED AS NO BONDING MATERIAL WAS PRESENT AND, THEREFORE, FURTHER TESTS WERE CARRIED OUT BETWEEN CONCRETES FACES TO RESEMBLE THE FUTURE SITE CONDITIONS MORE CLOSELY. /AUTHOR/
