Brief Description of Research on Temperature Field and Temperature Stress of Prestressed Concrete Girders

Abstract

This paper introduces the establishment and simplification of the temperature field and the general calculation method of temperature stress of the prestressed concrete box girders. Data from some research was extracted and the relative errors of the calculation and observation were compared. We indicate that the study of temperature field and thermal stress of prestressed concrete box girders is necessary, and will help engineers to solve the problem in structure design.
