Abstract

For the types of columns used are square columns (KP), hollow columns (KB) and square reinforcement columns (KPP) with dimensions used measuring 400 mm x 400 mm with 12D16 main reinforcement and stirrup reinforcement Ø10-150. The perforated column uses a 3 inch (7.5 cm) hole ratio, for CFRP thickness of 1 mm.

The results of the calculation of the interaction diagram for KP are Pn = 1785 kN and Mn = 292.06 kNm. The results of the KB calculation, the tensile collapse value Pn = 5733 kN and Mn = 934,479 kNm, for the compressive collapse value Pn = 2141.28 kN and Mn = 349,029 kNm. The results of calculations from KPP, namely Pn = 2166 kN and Mn = 373.28 kNm. The effect of CFRP strength on KP is Pn = 38% and Mn = 127%. Generally, in a building, the column will be given a hole with a certain ratio (<4% of the cross-sectional area), and it results in a decrease in strength of the column.
