What is Study on the disaster mechanism of near-fault pulse-like ground motion of M8.0 Wenchuan earthquake about?

## Abstract With the improvement of observation quality, more and more near-fault strong earthquake records have been obtained. Through the analysis of near-fault strong ground motion records of Wenchuan earthquake, the collection and field investigation of seismogenic structural data, as well as the collection and field investigation of near-fault structural damage data, the disaster mechanism of Wenchuan earthquake is studied. The impulsive ground motion (directional effect, permanent displacement effect, etc.) near the fault is determined. It is confirmed that the pulse-like ground motion (directivity effect, permanent displacement effect, etc.) near-fault is the main cause of earthquake damage. Pulse-like ground motion has the characteristics of high peak value, wide frequency band and long duration. Therefore, it is easy to resonate with the structures with different basic periods, thus causing serious direct disasters and indirect secondary disasters.
