Method for calculating maximum crack width of configured high-strength reinforced concrete beam

The invention relates to the field of civil engineering structure design and construction, in particular to a method for calculating the maximum crack width of a configured high-strength reinforced concrete beam, wherein CW is the crack width correction coefficient of a flexural member, and the value is 0.8; alpha cr is a stress characteristic coefficient of the component, psi is a strain non-uniform coefficient of longitudinal tensile steel bars among cracks, sigma s is a longitudinal tensile common steel bar stress of the reinforced concrete component calculated according to a load quasi-permanent combination or a longitudinal tensile steel bar equivalent stress of the prestressed concrete component calculated according to a standard combination, and Es is an elastic modulus of the steel bars. Cs is the distance from the outer edge of the outermost longitudinal tensile steel bar to the bottom edge of the tensile area, deq is the equivalent diameter of the tensile high-strength steel bar, and rho te is the r
