Numerical simulation of irregular section underground structure shaking table test model
Based on the the large shaking table test results on irregular section subway station structure in soft soil, an overall time-history numerical simulation is conducted to study the nonlinear dynamic interaction of the soil-irregular underground structure. Typical test results, including the acceleration of the soil, acceleration, and deformation of the structure, were analyzed. Satisfactory consistency between the simulation and test results is verified, and the difference between these results was discussed in detail. The maximum inter-story drift ratio was approximately 1/472 under input PGA = 0.54 g. The strain responses of columns were significantly larger than those of the side walls and slabs. The components in the lower layers of the irregular subway station structure, particularly in the central columns, underwent cumulative damage. The research results could provide a simplified analysis method to quantitatively evaluate the damage of irregular underground structures in soft soil.
