| Abstract: | First, 12 unbonded PPC beams with various shear -span ratios,various prestressing degree and different reinforcement amounts of stirrup and longtitute steel bar have been tested to study the shear strength. By discussing the factors affecting the shear strength of unbonded PPC beams and the failure mode of inclinded section of the beams,an empiric formula for calculating the shear strength has been presented. |
