Experimental Study on Seismic Performance of Tall Building Structure of Concrete Filled Steel Tube (CFST) with Transfer Story
The seismic performance test of the model CFST tube structure with transfer story has been finished. The model with 13 floors and with a scale of 1:10 consists of an outer-tube and an inner-tube. The former is a framed tube supported on CFST frames and the latter is an RC tube. A series of seismic performance tests of the model, which is equivalent as two degrees of freedom system, on acceleration earthquake waves in four cases (0.22g, 0.4g, 0.62g and 1.0g) have been fulfilled. The experiment has illustrated that the CFST tube structure is an outstanding structural style with excellent anti-seismic behavior.
