Abstract

To investigate the dynamic response characteristics and patterns of underground grain silos subjected to seismic waves from different incident directions, viscoelastic boundaries were employed to simulate the infinite foundation as a continuously distributed spring-damper system on artificial boundaries. A soil-underground grain silo structural model was developed using ABAQUS, into which horizontal seismic waves, vertical seismic waves, and horizontally-vertically coupled seismic waves were input. The acceleration, displacement, and stress responses of the underground structure were analyzed. The results indicate that the maximum horizontal acceleration of the silo wall under coupled seismic action increases by approximately 6% compared to that under horizontal seismic action alone, and the maximum vertical acceleration of the silo wall under coupled seismic action increases by about 12% compared to that under vertical seismic action alone. Therefore, the silo wall exhibits a more significant response under coupled seismic excitation, with a greater impact on vertical seismic effects. The position of maximum tensile stress occurs at the bottom of the silo wall under horizontal and horizontally-vertically coupled seismic waves, whereas it appears at the top of the silo wall under vertical seismic waves.
