Selecting typical steel cables to test,the friction factor between the cable and the tube is calculated based on the stressing force in passive end and elongation value of each cable. The design value of friction factor and elongation are defined by comparing the value calculated in test with the value of design.
Keywords:  strand; stressing; friction factor; elongation; stressing force
