B102 APPLICATION OF NUMERICAL SIMULATION AND VIBRATION MEASUREMENT FOR SEISMIC DAMAGE ASSESSMENT OF RAILWAY STRUCTURES

抄録

In this study, the authors discuss the methods to assess the future/actual damage of RC structures by using the numerical simulation and the vibration measurement. First, the applicability of the AEM is examined as an assessment tool for the seismic performance of RC structures. with/without retrofit construction, by means of the simulation of cyclic loading test and seismic response of RC structures. Next, the method to improve the accuracy of vibration diagnoses of earthquake-damaged RC structure is discussed by using the damage judgment criteria calculated by AEM.
