| 要旨 | 1. INTRODUCTION There have been many researchers on flexural and tensile cracks of reinforced concrete members. However, little has been done about shear cracks. In this study, experimental work was conducted to clarify shear crack behaviour of reinforced concrete beam with plain and deformed stirrups. Stirrup strain and vertical deformation of cracked concrete along stirrups in addition to stirrup hook slip, shear crack width corresponds to slip of bar at crack, slip-strain relationship at stirrup-crack intersection is looked at in detail. The slip is obtainedly by integrating the stirrup strain. 8. CONCLUSIONS Based on the experimental results, the following conclusions can be drawn. 1) Slip-strain relationship for plain and deformed stirrups at crack-stirrup intersection is clarified for static and cyclic loading. 2) Vertical displacement at crack is produced by not only elongation of stirrup leg, but also slips at hook and lower bent portion of stirrup. 3) Variation of width of shear crack and shear displacement along shear crack is dependent on the distances from the position considered to the crack tip as well as to the nearest stirrup. |
