Unified Design of Tensile-Compression Prestressed Concrete Structure
Structural characteristics of tensile-compression prestressed concrete are introduced briefly in this paper. Firstly, with current concrete structure design code(GB50010), requirements for materials used in tensile-compression prestressed concrete structure are put forward; and for prepressing stress steel pipe, strength value and basic types for structure design are determined. Secondly the calculation method of prestress loss is given during each work stage of tensile-compression prestressed concrete; and the basic measures of cracking control are concluded. Thirdly, bearing capacity formula of tensile-compression prestressed concrete structure and stress checking formula of menbers in construction stage are provided. Finally structure design of tensile-compression prestressed concrete is unified.
