| Abstract: | The mathematical analytical method is used to anlayse the prestress effect on the behaviors of concrete filled steel tubular axial compressive menbers. And a series of the whole stress-strain relationships of axial compressive members with prestresses is obtained. The test results coincide with the analytical results. The modified design formulae and modified coeficients of composite indexes are given also. |
