| Abstract: | An experimental study and numerical analysis on eleven reinforced concrete(RC) beams and four partially prestressed concrete(PPC) beams strengthened with U-shaped steel strips were carried out under static loading.The influences of damage degree,ratio of shear span and effective depth of section,stirrup ratio,spacing of the steel strips,level of effective prestressing,and thickness of steel strips on the shear performance of these strengthened beams were investigated.Some conclusions are drawn from the test... |
