Abstract


Prestressed composite structure is a composite structure developed on the basis of a new structure, it takes full advantage of the concrete , steel and high-strength prestressed steel beams three advantages of pressure and tension , which in a way avoiding their disadvantages , it has a prestressed concrete structure can not match advantage. Outsourcing angle prestressed concrete structures is a form of prestressed composite structure . Based on the extensive collection of existing relevant research data and abroad on the basis of theoretical analysis and numerical calculation method of combining the performance of its force . This paper studies the outsourcing angle prestressed concrete structures prestressing techniques and methods and flexural capacity of rectangular cross-section , cross-sectional bias capacity and ultimate capacity axial tension member , and gives the corresponding section in the form of limit capacity calculation formula ; through the development of nonlinear analysis FORTRAN program , has been outsourced angle prestressed composite structure moment - curvature , load - deformation curve , and discusses its impact factor. Studies have shown that outsourcing angle prestressed concrete structure with high flexural capacity . More systematic theoretical calculations to establish the appropriate system for prestressed concrete structures outsourced steel to provide a theoretical basis for the promotion and application , has some theoretical significance and practical value.
