Abstract

For the force performance of continuous rigid bridge reinforced by in vitro prestressing. Firstly, the structural characteristics of continuous rigid bridge and the principle of in vitro prestressing technology are introduced, and then the basic methods of force analysis are elaborated. Then, the bending capacity of the normal section and the shear capacity of the diagonal section of the extracorporeal prestressing reinforced flexural members are calculated, and key parameters such as the ultimate stress value of the extracorporeal prestressing tendons and the ultimate distance of the steel beams to the edge of the compression zone of the cross-section are analysed. Finally, the problems and challenges in engineering practice are discussed and the future development direction is proposed.
