dynamic pressure (4) The associated failure mode (5) The stress-strain relation of the liner steel and reinforcing and/or prestressing steel and the behavior of the liner under the postulated loading conditions in relation to that of the reinforcing and/or prestressing steel (6) The criteria governing the original design and the criteria used to establish failure (7) Analysis details and general results (8) Appropriate engineering drawings adequate to allow verification of modeling and evaluation of analyses employed for the containment structure L. Structural Audit. Appendix B to SRP Section 3.8.4 describes the conduct of a structural audit. M. Design Report. The design report is considered acceptable when it satisfies the guidelines of Appendix C to SRP Section 3.8.4. 5. Structural Acceptance Criteria A. For the structural portions of the containment, the specified allowable limits for stresses and strains are acceptable if they are in accordance with Subsection CC-3400 of the ASME Code and RG 1.136 (see Subsection II.3 of this SRP section), with the following exceptions: CC-3421.5 For existing (older vintage) plants where a portion of the tangential shear stress, vc, was permitted to be carried by the concrete, vc is limited to 276 kPa or 40 pounds per square inch (psi) and 414 kPa (60 psi) for the load combinations of Table CC-3230-1, representing abnormal/severe environmental and abnormal/extreme environmental conditions, respectively. The criteria for design of steel reinforcement to resist the excess shear load above vc should meet the provisions of the code of record for the containment design. 3.8.1-18 Revision 2 - March 2007 For other plants, the concrete should carry no tangential shear stress as indicated in Subsection CC-3421.5 of the ASME Code. The tangential shear strength provided by orthogonal reinforcement should be limited to the following: (MPa); [10 (psi)] 0833 . 'f c f c' where the value of is in units of MPa and psi in the first and second f
