Abstract: Abstract: Based on the TsaiWu yield criterion, the stress analysis of fiber reinforced polymer (FRP) tubes was conducted. And the twin shear unified strength theory was used to analyze the stress of the core concrete under triaxial stress state. Besides, the strength calculation method to predict the ultimate stress under axial compression of short concrete columns with rectangular crosssection confined by FRP tubes was deduced to provide an effective method and the reference for the calculation of the ultimate bearing capacity.

Key words: fiber reinforced polymer (FRP) tubes, short concrete columns, axial compress, stress model
