Cyclic Performance of TR-CFT Columns under Flexural Loadings

초록

This paper presents an experimental test and analytical modeling for CFT concrete filled steel tubes (CFT) and TR-CFT (Transversely- Reinforced Concrete-Filled Steel Tubes) under combined axial compression and cyclic loading. Modified P-M curves with the confining effect are also presented to predict the flexural capacity of CFT and TR-CFT. Test results were found to be in good agreement with the predicted values from the modified P-M curves.
