INVESTIGATION OF ASEISMIC DESIGN METHOD OF THREE-HINGE PRECAST ARCH CULVERT BASED ON SHAKING TABLE TEST AND NUMERICAL ANALYSIS

Abstract

 Three-hinge precast arch culvert is a flexible structure due to hinge functions in the main body and is based on the different design concept of conventional culverts. Therefore, the conventional design method which does not consider the earthquake behavior cannot be applied. So far, the authors had conducted large-scale shaking table tests targeted for the culvert of 1/5 scales to confirm the damage morphology by using a strong earthquake response simulator. In this study, two types of analyses, dynamic analysis and static analysis, for the shaking table test were carried out to investigate the numerical analytical approach relating to aseismic design of the culvert. From results, the static analysis would be an effective aseismic design method because the analysis reproduced the damage progression of the culvert.
