DUCTILITY OF HOLLOW RC SHORT COLUMNS IN COMPRESSION REGION
ABSTRACT: Five reinforced
concrete short rectangular columns with hollow made from PVC pipe that placed
in the center of cross section were
tested under eccentrically axial loading
in compression region with load eccentricity of 60mm (e < eb). The hollow ratio was taken from 3.63% up
to 20.28%, and concrete strength used was 34.52MPa. The columns had four
longitudinal steel reinforcements of 12mm diameter were symmetrically placed in
both sides of the square column section
with average yield strength of 323.06MPa, and average modulus of elasticity of
257411.49MPa. The objective of this
research is to study the ductility of hollow RC short columns with square cross
section of 150mm x 150mm. The results show
that generally all
columns give significant
difference in ductility
escalation. The maximum
ductility escalation was occurred
at column with maximum hollow ratio (20.28%), that is 16.38%, compared
relatively to the solid column. It could
be stated that PVC pipe installation in column will improve the ductility.
