Abstract: Ductility and
flexural strength are two important parameters in designing columns.
Moment-curvature curve can be used to determine the ductility of columns. In this
paper, moment-curvature analysis is conducted to investigate the effect of some
parameters on flexural strength and ductility of reinforced concrete columns,
steel reinforced concrete columns and steel columns. The parameters are
longitudinal bar area, transverse reinforcement spacing, steel section area and
its shape, concrete strength, longitudinal and transverse rebar yield strength.
The analysis is conducted by using ‘XTRACT’. Analysis results show that closer
transverse spacing, lower concrete strength and lower longitudinal bar yield
strength increase the ductility of RC columns. However, bigger longitudinal bar
area and lower transverse rebar yield strength decrease the ductility. In
addition, the configuration of longitudinal bars may influence the ductility
of columns. SRC column with H-shaped
steel has a higher ductility than that with I-shaped steel since H-shaped steel
provides higher confinement effect than I-shaped steel.
