Abstract:
his paper presents the results of transmission length tests on 28 pre—tensioned members made ofprestressing reinforcement with helical rib(PC steel bars)．The compressive strain and stress of concrete with—in the prestressing transm ission zone for the PC steel bars of the members are analyzed，and the factors affect—ing the transmission length of PC steel bars in concrete are also discussed，and a formula for calculating thetransmission length is suggested．The result can provide reference for the application of PC steel bars in con—crete strueture．
