N2 - In this study, cyclic lateral loading tests were performed with eight simply-supported SHS column to reinforced concrete grade beam subassemblages to investigate the effect of rebars surrounding column on ultimate resistance determined by punching shear failure. In the tests, embedment lengths of column, presence of U-shaped and/or hoop rebars were taken as test parameters. From the test results, the specimens whose columns were surrounded with U-shaped and/or hoop rebars exhibited larger strength capacity, smaller strength deterioration compared to the specimens whose columns were not surrounded with rebars. Static equilibrium at column face cross-section revealed that the rebars surrounding the column mostly resisted to resultant bearing force in the loading direction in post-punching shear crack resistance. The results provided fundamental insight on the developments of more reliable strength estimation model and concise reinforcement details.
