To solve the weak part of joints with specially shaped column frames, the joint of specially shaped column frames reinforced by steel fiber and the one without reinforcement in the core zone were tested under low cyclic loading.The results in terms of damage characteristic, stirrup strain and concrete strain variation in the core area of joint and shear behavior of joint with specially shaped columns were compared in order to research the mechanical behavior of weak part of joints with specially shaped columns reinforced by steel fiber.It is shown that the damage characteristic of joint reinforced by steel fiber is improved.The stirrup strain of joint reinforced by steel fiber is lower at beginning loading.The stirrup strain in parallel to the direction of shear force in web of joint with specially shaped columns is higher than that of in perpendicular and that of in the flange.The tensile strain for concrete in web and the shear capacity of joint reinforced by steel fiber are higher than that of without reinforcement.
