要旨 Using specimen in which expansive mortar is cast, experimental tests simulating ASR are performed. Through observations with time, the general specimen has reproduced the ASR-induced circular deformation. From detailed evaluation, the corner concrete has opening deformation with angular increment around 0.83?. By recording stirrup shapes before and after expansion, the bent part of stirrups is verified to have angular variation as 1.85?. The opening deformation of stirrups, with rough correlation to that of concrete, is considered to be influential on stirrup fracture.
