regions on the overall behavior of the containment may be treated in the same manner as for localized loads discussed in item (c). 3.8.1-10 Rev. 1 - July 1981 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 usually anchored at relatively closely spaced intervals, the analysis procedures are acceptable if based on either the classical plate or beam theory. Since the concrete shell is much stiffer than the liner plate, the strains in the liner will essentially follow those in the concrete. The strains in the concrete under the various load combinations as obtainable from the analysis of the shell are thus imposed on the liner plate and the resulting strains and stresses in the liner and its anchors should be lower than the allowable limits defined in Tables CC-3720-1 and CC-3730-1 of the Code. j. Ultimate capacity of concrete containment An analysis should be performed to determine the ultimate capacity of the containment. The pressure-retaining capacity of localized areas as well as of the overall containment structure should be determined. The analysis should be made on the basis of the allowable material strength specified in the Code. However, if the actual material properties such as concrete cylinder compressive strength, mill test results of reinforcing steel and liner plate, strength variations indicated by mill test certificates and other uncertainties are available, the lower and upper bounds of the containment capacity may be established statistically. The details of the analysis and the results should be submitted in a report form with the
