FLEXURAL DUCTILITY OF R/C RECTANGULAR COLUMNS UNDER HIGH COMPRESSIVE AXIAL FORCE USING SD490, 685N/mm2, 785N/mm2 CLASS TRANSVERSE REINFORCEMENT

FLEXURAL DUCTILITY OF R/C RECTANGULAR COLUMNS UNDER HIGH COMPRESSIVE AXIAL FORCE USING SD490, 685N/mm2, 785N/mm2 CLASS TRANSVERSE REINFORCEMENT

The author proposed the formulas for estimating the flexural ductility of R/C square columns and rectangular columns. However, the calculated values by the formulas of rectangular columns are not verified with tests result. In this study, tests of R/C rectangular columns with SD490, 685N/mm2 and 785...

Zusammenfassung:The author proposed the formulas for estimating the flexural ductility of R/C square columns and rectangular columns. However, the calculated values by the formulas of rectangular columns are not verified with tests result. In this study, tests of R/C rectangular columns with SD490, 685N/mm2 and 785N/mm2 class transverse reinforcement have been conducted under high compressive axial force. Based on these tests result, the accuracy of estimated ultimate strength and flexural ductility of R/C rectangular columns is clarified.
