Abstract:SummaryThe ACI 318‐14 building code requirements specify that the net tensile stresses of prestressing strands under service loads (Δfps) shall be limited to 250 MPa for proper crack control of prestressed concrete (PC) members which are classified as Class C. However, as high‐strength prestressing strands with a tensile strength of 2,400 MPa have recently been developed and applied to PC members, this requirement needs to be reviewed. In this study, experiments and analysis were carried out in order to invest… Show more
