Orthogonal Analysis on T-Shaped Concrete-Filled Steel Tubular Column Seismic Performance Based on the Finite Element Analysis Results

Abstract:

By the analysis of seven factors’ influence on the ultimate bearing capacity, the ductility coefficient and the energy consuming ability of the T-shaped concrete-filled steel tubular column and comparison to the significance degree of influence through the orthogonal test ,which are the axial compression ratio, the strength of the concrete, the thickness of the steel tube ,the strength of steel tube, load angle, length and limb high ratio. The result shows that: limb high ratio effects the ultimate load of the T-shaped concrete-filled steel tubular column most; the concrete strength effects the ductility coefficient most; the steel tube strength effects the equivalent viscous damping coefficient most.
