000022070 520__ $$2eng$$aBased on the IDA method for seismic evaluation of superstructure, an IDA method for seismic evaluation of underground structure was proposed in this paper. The feature of IDA and its implementation procedures were introduced in detail. Combined with an engineering project, a two-dimensional finite element numerical model was proposed to analyze structural seismic response through finite element analysis software ABAQUS. 10 ground motion records were selected to provide sufficient accuracy in the estimation of seismic demands. Analysis result shows that IDA method can be applied successfully to underground structure and the difference between superstructure and underground structure using IDA method was also presented. Furthermore, the efficiency of different intensity measures was investigated. Two intensity measures were used, namely, Peak Ground Acceleration (PGA), Peak Ground Velocity (PGV) , and θmax was selected as the damage measure. The analytical progress and results are helpful for the performance-based seismic design of underground structure and a wide application of IDA in other complex underground structures.
