| Abstract: | The interaction within the compone nts of L-shaped concrete filled steel tube(CFT) stub columns with binding bars subjected axial load is analyzed.The L-section is divided into a square and two rectangular sections.The rectangular sections have binding bars while the square section has no one.The ultimate strength equations for L-shaped CFT stub columns with binding bars are proposed and the parameters of the equations are confirmed through experimental data.Finally,The experimental specimens are calculated... |
| Keywords: | L-shaped CFT sub columns binding bars confined concrete ultimate strength local-buckling |
