RESPONSE OF THE SUBSTRUCTURE OF A MAJOR BRIDGE TO EARTHQUAKE MOTIONS

THE DYNAMIC RESPONSE OF A HIGHWAY BRIDGE SUBSTRUCTURE IS CALCULATED FOR A GROUND MOTION ALONG THE BRIDGE AXIS AND ALSO TRANSVERSE TO IT. HOLZER'S METHOD WAS USED FOR DYNAMIC ANALYSIS AND THE INFLUENCE OF BENDING AND SHEAR DEFORMATIONS, AND INERTIA WAS CONSIDERED. THE EFFECT OF VARIABLES SUCH AS VIRTUAL WATER MASS, WATER FILLED HOLLOW PIERS, LIVE LOAD MASS, INERTIA FORCE OF THE SUPERSTRUCTURE AND SOIL RESISTANCE WAS INVESTIGATED. IN THE MODAL ANALYSIS, THE SECOND MODE OF VIBRATION WAS FOUND TO BE AS IMPORTANT AS THE FIRST MODE, WHILE HIGHER MODES WERE NEGLECTED. /TRRL/
