Zhengyangmen gate tower is a national emphasis cultural relic unit along the north-south axis of Beijing, which is above the Beijing metro line 2. Based on dynamic analysis model of gate tower and the position of gate tower and subway, the dynamic response characteristics of gate tower induced by Beijing metro line 2 are calculated, and compared with the in-site vibration test data.

This paper presents the model updating technique for satellite structure by using the vibration environment test data. In the paper, several key technique issues related to the model updating of satellite structure, such as selection of updating parameters, model reduction, damping identification, etc, have been discussed. As an example, the model updating for a satellite central cylinder structure using the shaker vibration environment test results is described. It is proved that the techniques presented are effective for engineering applications.
