BRIDGE DYNAMIC RESPONSE ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a bridge kinetic response analysis method which can find impact coefficient with complexity fewer than a finite element model.;SOLUTION: A method analyzing dynamic response of a bridge when a train runs includes the steps of: inputting input data of the bridge, the train and numerical analysis; calculating displacement response from the input data and a formula (1)/a formula (27); calculating speed response from the input data and a formula (2)/a formula (28); and calculating an impact fraction from the relation of the speed response and the displacement response.;SELECTED DRAWING: Figure 8;COPYRIGHT: (C)2017,JPO&INPIT
