[I-222] Seismic Performance Study of Spherical Storage Tank with Pile Foundation by Three-Dimensional Effective Stress Analysis
Keywords:Three-dimensional FEM model, Effective stress analysis, spherical storage tank, Maximum curvature of pile
Earthquake waves expected to be generated in the Uemachi fault zone were created for the spherical storage tank, which is a high pressure gas facility, and three-dimensional effective stress analysis was performed by two-way horizontal input to study the earthquake resistance of the superstructure and foundation structure. The target storage tank is a spherical storage tank (storage capacity 1000m3) designed based on the earthquake resistant design standard for high pressure gas equipment.
