Brief Analysis on Crack of Unbonded Partially Prestressed RPC Beam

Abstract:

Reactive Powder Concrete (RPC) has excellent properties such as high toughness and high durability. In this paper, based on the experimental research of the different unbonded prestressed tendons of the unbonded partially prestressed RPC beams, the crack calculation of prestressed RPC beams is analyzed. The results show that the crack regulation is special in some extent of the unbonded partially prestressed RPC beams. It is suggested that the crack width of unbonded partially prestressed RPC beams calculated in accordance with the specification for unbounded partially prestressed concrete structure should multiply the reduction factor of 0.7.
