Different Types

Five different types of self-compacting unbonded prestressed concrete beams are designed to study the bearing properties of self-compacting prestressed concrete flexural members. And experimental studies are conducted on their cracking loads, flexural strengths, ductility of members and failure forms. The testing results provide references for design and establishing related codes of self-compacting prestressed concrete structures.

Dynamic Performance

By the method of plane charge on the tested beams, this paper studied 6 pieces of beams， dynamic performance by 4 time loadings, displayed the deflection waveform curves, measured the bearing ability of beams with different prestress degree, analyzed the effects of the deformed performance and the ductility of the test beams with the different prestress degree. The 6 pieces of PC（prestressed concrete）beams was divided into 2 groups.

Bond Behavior

To study the influence of steel strands corrosion on the bond behavior for anchoring of pre-tensioned prestressed concrete beams, nine specimens were fabricated. Of which, 5 beams were mixed with salt and set in different places to be corroded in different intensity for 13 months. Then the load test was held to all the 9 specimens and the load-slip curves were obtained. The results show that under the condition of no corrosion crack, the short-term anchoring bond strength of pre-tensioned prestressed concrete beams increases for the steel strands corrosion. Because the tension behavior of steel strands deteriorates remarkably even if the corrosion is slight, which is the dominant cause for the degradation of fundamental structural behavior, the influence of steel strands corrosion on the bond behavior for anchoring may be ignored.
