Strength Design of Pretensioned Flexural Concrete Members at Prestress Transfer

摘要

This paper presents a rational method for the design of pretensioned flexural concrete members due to the effects of prestress transfer. Conditions at prestress transfer often control the level of prestress that can be placed in pretensioned flexural mem - bers. The level of prestress significantly influences the maximum span capability. It is proposed that the flexural design of pretensioned, prestressed concrete members for the effects of prestress trans - fer be based on strength design criteria.
