Formula of Unbonded Tendon Stress Increment Based Performance

Abstract:

Unbonded tendon stress calculation of unbonded precast concrete structure is defferent from prestressed concrete structure, as tendon strain caused by the external load is not in accordance with relevant sections of the concrete strain obtained. As the deformation of unbonded tendons are not subject to the deformation of plane-section assumption, therefore, arise due to external loads of unbonded tendon stress calculation is more complex. In this paper, based on theoretical analysis and derivation, the pre-stress deformation of the unbonded steel stress formula was given, this can provide more scientific basis for the stress Analysis of unbonded precast frame structure.
