| Abstract: | The unbonded beams of partical prestressed reinforced concrete(PPRC) recessed are studied experimentally. Based on the experimental results,the load prestress,the stress forereached of the axial tension steel and something of the recessed concrete beam such as the strain delay,the average cross-section strain, the relationship between load and deflection,the strain distribution and the failure features of the rescessed concrete beam, are all analysed in detail. The test data are available for calculating the section load-bearing capacity of the unbonded recessed beams of PPRC. |
| Keywords: | unbonded partial prestressed concrete recessed beam deflection crack |
