【 摘 要 】

According to the incremental dynamic analysis method (IDA), the intensity amplitude of one or more seismic records is adjusted step by step, and then one or more sets of seismic records with increasing intensity are generated. The seismic records are used to perform nonlinear dynamic time history analysis of the bridge-integrated structure one by one until structural damage. Therefore, a comprehensive and realistic evaluation of the seismic capacity of the bridge-building station structure is made, and the response of the structure under the action of rare earthquakes and multiple earthquakes is deeply understood. This paper provides a reference for practical engineering design.
