Abstract

Abstract

Prestressed steel reinforced concrete (PSRC) is the combination of modern prestressed concrete technology and steel composite structure technology, which can create conditions for the realization of larger span and larger space of building structures. The redistribution of plastic internal force and moment of PSRC continuous beams have different characteristics. The existing research is rarely reported, and there is no regulation in the relevant national codes. Therefore, it is necessary to study the theory of moment redistribution of PSRC continuous beams. In the study, the influence of the relative compression area height of the bearing section, the strength ratio of bearing to midspan, the steel ratio and the secondary moment on the redistribution of plastic internal force and the moment of the two-span PSRC continuous beams were studied by the redistribution of plastic internal force and the moment redistribution of the two-span PSRC continuous beams.
