EXPERIMENTAL STADY ON SHEAR STRENGTH OF RC COLUMNS TRANSVERSELYREINFORCED WITH COMBINATION (CB) PANEL METHOD

T.Kuroiwa, R.kasakura, M.Suzuki
M.Ito, M.Aoki, and M.Miwa
We developed a retrofitting method (ComBination panel method) for reinforced concrete column with using highstrength precast concrete panels and high strength fiber reinforced mortar. In order to investigate the seismic performance ofretrofitted columns with CB panel method, two full scaled units were constructed and tested under lateral loading. The test
units demonstrated different failure mode corresponding to the amount of the shear reinforcement. No.1 unit with less shear
reinforcement failed in shear. On the other hand, No.2 unit with more shear reinforcement exhibited stable hysteresis loopswith good energy absorption. The design shear capacity was estimated in accordance with the truss theory.
