Yunian International Commercial Affairs Building is a complex high rise building with mega-laminated truss transfer story. The prestressed concrete laminated truss transfer story with very large span and high vertical load demand is the key technological challenge for the entire structural design and construction. To investigate its seismic performance, a 1:25 reduced scale structure model of Yunian International Commercial Affairs Building was tested on shaking table. The dynamic properties of the model structure were studied. The test was conducted, inputting the El Centro earthquake wave, the Pasadena earthquake wave and the Shw2002 earthquake wave in four intensities, i.e. the frequent intensity, the fortification intensity, seismic rare intensity and the strong and rare intensity for seismic regions of 7 and 8 degree respectively. The model responses of acceleration, displacement and strain were measured under different earthquake waves. The failure mechanism and the cracking pattern were discussed as well. The experimental results show that the model structure can meet the design requirements for seismic regions of intensity 7, i.e. no damage under frequent earthquakes and no collapse under rare earthquakes. Collapse of the structure can be prevented for rare intensity for 8 degree. Thus the structure has adequate seismic performance. The prestressed concrete laminated transfer truss is basically in elastic range under the earthquake action of the frequent intensity, the fortification intensity and the rare intensity 7.
