Research on Prestressed Loss in Curving Hole of Prestressed Concrete Structure Caused by Frictional Resistance

Abstract:

Excessive prestressed loss in prestressed concrete continuous beam bridge and continuous rigid frame bridge causes structures appearing different types of diseases. By theoretical analysis on computational expression of effective prestress in curving hole, and distribution of contact stress and experiment about prestressed loss caused by frictional resistance, this paper points out the disadvantages of current effective prestress formula in curving hole. According to the research on the major influencing factors of prestressed loss in curving hole-contact status and friction coefficient μ, it plays a remarkable role on the further analysis of prestressed loss in curving hole.
