Comparison Between Longitudinal and Transverse Shaking of Culvert–Frame Combined Underground Structure

Year: 2025

Type: article

Abstract: Owing to the special configurations of the culvert–frame combined underground structure, discrepant responses at different portions of the structure arise when earthquakes strike in the longitudinal direction. This paper presents other experiments when shaking along the lateral direction and comparing structural dynamic responses between these two cases. Data on accelerations and culvert joint displacements were presented under a series of 1 g shaking tests, that is, five synthetic earthquake motions between white noise cases. Comparing the seismic responses of the culvert–frame structure under varying intensities of excitations gave findings that, with respect to longitudinal excitation, the acceleration responses of the model soil were increased under transverse excitations. For the model structure, the acceleration responses under longitudinal excitations were larger than those of transverse excitations. A significant difference in the displacement of the culvert joint was observed.
