Abstract

Abstract

Based on flexural experiment of the partially prestressed concrete beams with 600 MPa steel bars, the development laws and influencing factors of stress increment of unbonded prestressed tendons were analyzed. The formula for calculating the ultimate stress increment of the unbonded prestressed tendons, adopted to partially prestressed concrete beams with 600 MPa steel bars was proposed.The results indicated that there was only a slight growth of stress increment of unbonded prestressed tendons in earlier stage, while the non-prestressed steel bars bore the majority of tensile stress. The growth of stress increment of tendons accelerated obviously after steel bars yielding, resulting in full use of strength of 600 MPa steel bars.Through checking and calculating the ultimate stress increment for 69 beams,the results showed that the proposed formula had the reasonable applied scope and high accuracy.
- partially prestressed concrete beam,
- 600 MPa steel bar,
