Structural Safety and Reliability of Post-Tensioned Floor-Slabs
Gilbert Raynard, BASc, P.Eng., Struct.Eng., PE, SE | Principal

Post-tensioning with unbonded tendons offers great advantages for floor-slabs. Design and construction have to consider that a local damage accounts to the total loss of the tendon. The paper puts emphasis on the combination of prestressed and mild reinforcement and makes suggestions how to improve the reliability, ductility and redundancy of post-tensioned floor-slabs.
