PENGARUH LUBANG PADA INTI KOLOM TERHADAP DAKTALITAS

Conduits (pipes) in reinforced concrete columns is still use to date. SNI 03-2847-2002 Code limits up
to 4% of the column cross section. But the codes does not mention the effect of the hollow cross section
ductility.This study was done by testing hollow and solid column with four variation, column cross
section b=h= 200 mm x 200 mm, column length L = 1.500 mm, hole ratio (0%; 3,32%; 5,68%;
12,31%), single stirrup. End of the column are loaded by conctant axial compression 5,0 ton, lateral
load are applied at ½ span until ultimate strength. The observed variables are lateral load and
deflection.The result of the study shows momen strength hollow column experience is decline 4,04%
at hole ratio 3,32%; 7,99% at hole ratio 5,68% and 21,66% at hole ratio 12,31%. Ductility for column
with hole ratio 3,32% and solid column same asumed.The experiment also indicates ductility within
range of 7.683
