Abstract
When a long suspension bridge which has relatively small ratio of side span length and center span length is designed, friction resistance between cable and saddle becomes an important problem. An experimental investigation was performed by use of equipment which simulated condition of real bridge. As the result, the slipping behavior of cable was made clear. Furthermore, it became clear that maximum friction coefficient came to about 0.33 in the case that contact surface of saddle was as ground-off, but about 0.48 if this saddle surface was galvanized with pure zink.
