dered should be such that the shear demand and flexural demand are maximized. (3) Where rigorous nonlinear dynamic time history analysis is used in the design for impulse or impact loadings, the input parameters and stress and strain limits used as acceptance criteria for section strength should be specified and the rationale adequately justified. 9. CC-3542 Loss of Prestress In addition to provisions in CC-3542, RG 1.35.1 should be used for guidance in determining loss of prestress in tendons. 10. CC-4240 Curing In addition to the specifications for curing concrete in CC-4240, curing and protection against physical and thermal damage from time of placement until end of minimum curing period should be in accordance with ACI 308.1-11, ACI 308R-16, and ACI 305.1-14, along with ACI 305R-10 or ACI 306.1-90 (R2002) along with 306R-16 as applicable. 11. CC-4333 Mechanical Splices and Mechanically Headed Deformed Bar Systems and CC-4334 Arc Welded Joints The acceptance criteria of paragraph CC-4333 for performance and qualification testing of mechanical splices and mechanically headed deformed bar systems, and paragraph CC-4334 for qualification of arc welded joints, should be supplemented as follows consistent with Regulatory Position 8.d: a. In CC-4333.2.3(a), “Static Tensile Tests”: (1) A tensile test on a specimen from the same bar used for the spliced and mechanically headed deformed bar specimens should be performed to determine the actual yield strength (fy_actual) and actual tensile strength (ft_actual). This test should confirm that the following conditions in CC-2331.2 and ASTM A706 are satisfied: (a) fy <= fy_actual <= fy+18, ksi [fy+125, MPa] (where fy is the specified minimum yield strength of the bar), and (b) ft <= ft_actual >= 1.25 fy_actual. (2) The tensile strength of an individual splice and mechanically headed deformed bar system should not be less than the specified minimum tensile strength (ft) of the reinforcing bar spliced. (3) The average
