Abstract

The present invention relates to a system and a method for calculating usability of a concrete track at an end part of a railway bridge, which comprises a step in which a calculation unit receives physical properties and specification of the bridge and the rail, physical properties of a coupler, and an interval value of the coupler from an input unit; a step in which the calculation unit uses the physical properties and specification of the bridge and the rail, the physical properties of the coupler, and the interval value of the coupler received to calculate force imposed on the coupler, thereby calculating a unit rotation amount, unit displacement and a vehicle wheel load; a step in which the calculation unit calculates rotation of the end part caused by long-term sagging of a bridge deck (creep and drying shrinkage), a static operating load, and a dynamic operating load; a step of applying a partial safety coefficient to the calculated values of the static load and the dynamic load to calculate a maximum value at each point; and a step of adding the combination value of the dynamic loads to a static load combination value, with which the static load is combined, to compare the resulting value with an allowable reference value and then review upward force. Additionally, a format of a bridge, arrangement of spans and the like are reviewed in planning and designing a railway bridge in order to secure usability of a concrete track at the end part of the railway bridge during interaction of a railway structure in which the concrete track is installed.
