DYNAMIC BEHAVIOR OF CANTILEVER BRIDGES UNDER MOVING LOADS

THE DYNAMIC BEHAVIOR OF DOUBLE CANTILEVER BRIDGES IS STUDIED UNDER MOVING LOADS. THE BRIDGE IS TREATED AS A BEAM AND THE VEHICLE IS REPRESENTED BY TWO SIMPLE MODELS: (1) A MOVING CONSTANT FORCE, (2) A MOVING SPRUNG FORCE. DETAILED NUMERICAL RESULTS ARE PRESENTED FOR FOUR BRIDGES OF DIFFERENT ASPECT RATIOS FOR THE MOVING FORCE PROBLEM AND FOR A FEW TYPICAL CASES IN THE MOVING SPRUNG LOAD PROBLEM. THE RESULTS OF NUMERICAL STUDIES ARE PRESENTED IN TWO FORMS: (1) THE AMPLIFICATION SPECTRA, AND (2) THE "HISTORY CURVES". /AUTHOR/
