This study investigates the seismic response of a concrete water reservoir subjected to the Northridge 1994 earthquake to identify the most critical locations for structural health monitoring of the reservoir based on the maximum deformation induced by the seismic load. The analysis employs a liner dynamic time history approach to assess the maximum deflection and stresses of the reservoir in two distinct scenarios: (i) empty and (ii) full water. The fluid–structure interaction is modeled using the finite element (FE) software, ANSYS©. Results demonstrate the developed model could be employed as a tool to conduct time history analysis and predict the transient response of the reservoir under seismic loads. Consequently, potential locations for installing structural health monitoring sensors could be identified based on analysis results.

摘要

This study investigates the seismic response of a concrete water reservoir subjected to the Northridge 1994 earthquake to identify the most critical locations for structural health monitoring of the reservoir based on the maximum deformation induced by the seismic load. The analysis employs a liner dynamic time history approach to assess the maximum deflection and stresses of the reservoir in two distinct scenarios: (i) empty and (ii) full water. The fluid–structure interaction is modeled using the finite element (FE) software, ANSYS©. Results demonstrate the developed model could be employed as a tool to conduct time history analysis and predict the transient response of the reservoir under seismic loads. Consequently, potential locations for installing structural health monitoring sensors could be identified based on analysis results.
