Abstract： The shaking table testing model of a complex steel-concrete composite super-tall building was tested. The height of the 53-storeyed building is 250m. There are three annular trusses between 5~6 storey, 20~22 storey and 37~39 storey, among which the second annular truss served as the strengthened storey and the third annular truss served as the strengthened and transfer storey. Through the transfer storey, office stories change into hotel stories, meanwhile mega-columns transfer to closed columns. Because the height of the building obviously exceeds the stipulated maximum height, a shaking table test of this building was made. In the test, the selections of the model material and the similitude relationship were analyzed, the section design and simplifications of the model were discussed, the fabrication of the model was related, and the error in the designation and fabrication of the model was analyzed.

Keywords: super-tall building; shaking table testing model; designation and fabrication; error
