public domain computer program. (iii) The computer program solution to a series of test problems has been demonstrated to be substantially identical to those obtained from classical solutions or from accepted experimental tests or to analytical results 3.8.1-13 DRAFT Rev. 2 - April 1996 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. f. Tangential shear Design and analysis procedures for tangential shear are acceptable if in accordance with those contained in Article CC-3000 of the Code. The exceptions taken by the regulatory staff to the provisions of this article, as contained in subsection II.5 of this SRP section, are to be noted. g. Variation in physical material properties For considering 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 in the analysis, wherever critical. Among the physical properties that may be critical include the soil modulus, and modulus of elasticity, and 47 Poisson's ratio of concrete. h. Thickened penetrations The effect of the large, thickened penetration regions on the overall behavior of the containment may be treated in the same manner as for localized loads discussed in item (c) subsection II.4.c.48 i. Steel liner plate and anchors For the design and analysis of the liner plate and its anchorage system, the procedures furnished are found adequate and acceptable if in accordance with the provisions of Subarticle CC-3600 of the Code. In general, the liner plate analysis should consider deviations in geometry due to fabrication and erection tolerances and variations of the assumed physical properties of the liner and anchor material. Since the liner plate is
