| Abstract: | Using truss model,the theoretical analysis was conducted to study the mechanism of steel wire in strengthening,and a model to predict shear capacity of reinforced concrete beams strengthened with prestressed wire stirrups was put forward.The calculation results agree well with the experimental ones,and the results obtained by code ACI 318-05 are conservative,therefore this model can be used to calculate the shear capacity of beam strengthened with prestressed wire stirrups,and the reduction of concrete shea... |
