EARTHQUAKE OBSERVATION RECORD OF THE 2018 NORTHERN OSAKA-FU EARTHQUAKE AND EVALUATION OF RESPONSE OF LONG SPAN TRUSS BRIDGE

Abstract

 To investigate the accuracy of the wide network simulation for Hanshin Expressway, seismic analysis was done for the long span truss bridge with the waves observed in the northern Osaka Prefecture around 7:58 on June 18, 2018.

 As a result, the periods of analytical results at the edge and center of girder in the long span truss bridge were a little larger than those of observation results, and the main eigen period of displacement waves were reproduced by the analyses. It means the structural model is useful in the seismic response analysis for the wide network simulation.
