Content:
temperature, wind, earth pressure, snow, rain, and ice, and construction loads that may be applicable such as material loads, personnel and equipment loads, horizontal construction loads, erection and fitting forces, equipment reactions, and form pressure. Structural Engineering Institute (SEI)/American Society of Civil Engineers (ASCE) Standard 37 gives additional guidance on construction loads for use in the load combination for construction given in Table CC-3230-1 of the ASME Code. When SEI/ASCE Standard 37 and the ASME Code/SRP provide conflicting criteria, then the ASME Code/SRP should govern. 4. Design and Analysis Procedures. The procedures for design and analysis used for the concrete containment, including the steel liner, are acceptable if found in accordance with those stipulated in Article CC-3300 of the ASME Code, with additional guidance provided by RG 1.136 (see Subsection II.3 of this SRP section). In particular, for the areas of review outlined in SRP Subsection I.4 above, the following procedures are, in general, acceptable: A. Assumptions on Boundary Conditions. The boundary conditions depend on the methods of analysis to be used and the portions of the containment shell to be separately analyzed. If the analysis is to involve the use of the finite element technique and is to include the foundation media, the boundary would be the demarcation lines separating the foundation mass taken into consideration in the analysis from the surrounding media. The boundaries of the foundation mass considered should be selected to provide comparable or conservative results to those corresponding to a further extension of the boundaries. This is reviewed on a case-by-case basis. 3.8.1-13 Revision 4 - September 2013 If the analysis considers only the containment shell and its basemat, then the bottom of the basemat is the boundary of the analytical model. The foundation media should be represented by appropriate soil springs. If separate analyses of the
