Abstract

Abstract

PSRCB is a new type prestressed composite beam which uses prestressing technology in SRCB. The H-section steel inside increases its flexural strength and prestressing technique improves its working performance. Eight PSRC beams and six SRC beams have been done and the development and distribution of cracks have been observed carefully. On the basis of the experiment, criterion of crack control and computation of maximum crack width of PSRC beam, and crack closing are discussed. Research indicates that PSRC beam has a better serviceable performance by contrast to SRC beam: better resistance to crack; smaller strain of tensile rebar and crack width; better crack closing performance.
