Draft Revision 4 - December 2012 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 within the range of applicability of the classical problems analyzed to justify acceptance of the program. A summary comparison should be provided for the results obtained in the validation of each computer program. G. Tangential Shear. Design and analysis procedures for tangential shear are acceptable if in accordance with those contained in Article CC-3000 of the ASME Code. The regulatory staff should note the exceptions taken to the provisions of this article, as contained in Subsection II.5 of this SRP section. H. Variation in Physical Material Properties. For the analysis of the effects of possible variations in the physical properties of materials on the analytical results, the upper and lower bounds of these properties should be used, wherever critical. The physical properties that may be critical include the soil modulus, modulus of elasticity, and Poisson=s ratio of concrete. I. Thickened Penetrations. The effect
