| 要旨 |
An experimental program was conducted to investigate the shear cracking behavior in I-shaped reinforced concrete and I-shaped partially prestressed concrete beams. All beams were tested under four point static monotonic loading by focusing on the influence of compressive stress in concrete due to prestress, stirrup ratio, side concrete cover, type of stirrup and longitudinal reinforcement ratio on the shear crack width. During the loading test, shear crack width was monitored close to stirrup strain gage attached by using digital microscope. |
