Study on the Shear Behaviors of RC Beams after Freeze-Thaw Cycles

In order to investigate the shear behaviors of RC beams after freeze-thaw cycles, static shear experiments of 45 RC beams after 0, 75, 100, 125, and 150 freeze-thaw cycles were made. The influences of different numbers of freeze-thaw cycles on the shear behaviors of RC beams with different stirrup s...

Zusammenfassung:	In order to investigate the shear behaviors of RC beams after freeze-thaw cycles, static shear experiments of 45 RC beams after 0, 75, 100, 125, and 150 freeze-thaw cycles were made. The influences of different numbers of freeze-thaw cycles on the shear behaviors of RC beams with different stirrup spacing were studied. The results show that Freeze-thaw cycle, stirrup spacing of reinforced concrete beam has no significant effect on crack distribution and failure pattern; cracking load and ultimate load of shear beams decrease with the increasing of freeze-thaw cycles.
