Abstract

Abstract

In the design of prestressed concrete beams, Intergral calculus is needed in calculating the geometric properties of irregular cross section. By presenting a case of externally prestressed beams with U-shaped cross section, a section equivalent conversion method is introduced, and the design process of externally prestressed concrete structure using the method of secondary interior force under restraint are also presented.
- external prestressing,
- equivalent conversion,
- secondary interior force under restraint
