Abstract EN
This research presents experimental behavior of eight rectangular reinforcement concrete columns of low compressive strength concrete which strengthened by steel jacket.
All the specimens were rectangular concrete column with aspect ratio equal two, 15 x 30 cm cross section, reinforced longitudinally by 6 bars 10mm diameter and transversely by ties 6 mm diameter each 15 cm.
The column was provided at the two ends by two caps 15 x 50 cm cross section and 22.5cm height.
The total length of the column was 165 cm.
The concrete cube strength of the columns was 200 kg / cm2.
The steel jacket consisted of vertical four angles in the corners and horizontal straps plates which were distributed along the length of column and welded between the corner angles.
The experimental behavior of the strengthened concrete column was studied with variable size of corner angles and different spacing of the strap plates using either anchor in the middle on the long side of the columns or without anchors.
The obtained results of the strengthened columns were plotted and the ultimate load was compared with the analytical analysis which was suggested by Wang [7].
The comparison between the results showed a good agreement for the ultimate load of the strengthened columns.
Based on the obtained results recommendations were issued.
