| Abstract: | The transient prestress loss includes the friction loss and anchorage loss.According to the characteristics of the tendon profiles in slabs,the uniform formulas for calculating transient prestress loss of prestressed tendons with different profiles and jacking modes in slabs are deduced in detail,and the effects of jacking modes and the distribution of prestress loss on it are also analyzed. |

| Keywords: | prestressed concrete slab\ friction loss\ anchorage loss\ transient prestress loss |
