cking is not considered or is determined to be insignificant. Sections 3.1.3 and C 3.1.3 of ASCE 4-98 provide additional guidance for modeling the stiffness of concrete elements. The staff reviews the methods used for considering creep, shrinkage, and concrete cracking, or the justification for not considering these effects, on a case-by-case basis. E. Dynamic Soil Pressure. Consideration of dynamic lateral soil pressures on embedded walls of a concrete containment (if applicable) is acceptable if the lateral earth pressure loads are evaluated for two cases. These are (1) lateral earth pressure equal to the sum of the static earth pressure plus the dynamic earth pressure calculated in accordance with ASCE 4-98 Section 3.5.3.2 and (2) lateral earth pressure equal to the passive earth pressure. If the above methods are shown to be overly conservative for the cases considered, then any alternative methods proposed will be reviewed on a case-by-case basis. F. Computer Programs. The computer programs used in the design and analysis should be described and validated by any of the following procedures or criteria: i. The computer program is recognized in the public domain and has had sufficient history of use to justify its applicability and validity without further demonstration. ii. The computer program’s solutions to a series of test problems have been demonstrated to be substantially identical to those obtained by a similar and independently written and recognized program in the public domain. The test problems should be demonstrated to be similar to or within the range of applicability of the problems analyzed by the public domain computer program. iii. The computer program’s solutions to a series of test problems have been demonstrated to be substantially identical to those obtained from classical solutions or from accepted experimental tests or to analytical results published in technical literature. The test problems should be demonstrated to be similar to or
