Design Method of Unbonded Partially Prestressed Concrete Flexural Members

DU Jin?sheng,LIU Xi?la (Dept.of Civil Engineering,Tsinghua University,Beijing 100084,China)  
In order to satisfy the requirements of both ultimate limit state and servicing limit state unbonded partially prestressed concrete flexural members must be reasonably designed.The paper estalished the design procedure of the above members.The area of unbonded prestressed steel and the area of nonprestressing tension steel were determined by the ratio of prestressing force to total tension force,and then the degree of prestressing was checked.Then the members′ flexural strength at ultimate,deflection,width of cracks and stresses at servicing load were analyzed.A design example was also given in the paper.
