Finite Element Analysis of Anti-shear Performance of Prefabricated UHPC Permanent Formwork Reinforced Concrete Composite Beam
In order to study the shear performance of precast reinforced concrete composite beam,select the appropriate U-type UHPC precast unit constitutive relationship,establish the finite element permanent model of reinforced concrete beam,and compare with the existing test data,verify the reliability of the model,and analyze the hoop rate,shear span ratio on the shear performance of high per-formance concrete composite beam.The results show that the UHPC precast unit can significantly improve the oblique cracking load and limit load;the precast unit can limit the effect of the stirrup,so the hoop rate has little impact on the combined beam;the shear span ratio affects the shear performance of the combined beam,but it affects the ductility.
