METHOD FOR EVALUATING BRIDGE USING INPUT-OUTPUT RELATIONSHIP OF LOAD AND RECORD MEDIA RECORDED PROGRAM FOR IMPLEMENT THEREOF

摘要

According to an embodiment of the present invention, a method for evaluating a bridge by using input-output relation of load includes the steps of: measuring input information of load imposed on the bridge; measuring a response of the bridge to the load; identifying the input-output relation of load by using the load and the response; improving a finite element model for interpreting the bridge by using the input-output relation of the bridge; determining whether the improved finite element model satisfies a target value; and evaluating the bridge by using the improved finite element model. According to the present invention, multi-input-output interpretation can be performed by using loading location information when known load is dynamically loaded, and the finite element model can be statically improved by using a number of data points. There are more data points when compared to an existing method, and the finite element model can be improved by using static interpretation. Therefore, time for calculation can be reduced.
