Content:
determining the overturning moment attributable to an earthquake should be in accordance with the methods described in SRP Section 3.7.2. Computer programs are acceptable if the validation provided is found to be in accordance with the procedures delineated in Subsection II.4.E of SRP Section 3.8.1. In addition to the above, the design and analysis procedures for the following details are reviewed on a case-by-case basis: A. Method for determination of the bending moments and shear forces in the foundation mat for seismic loads? 3.8.5-9 Revision 2 - March 2007 B. Performance of the sliding analysis method and how the analysis adequately accounts for potential foundation mat liftoff effects, if appropriate? The method to calculate the factor of safety against sliding. If sliding resistance is the sum of shear friction along the base mat and passive pressures induced by embedment effects, how these effects are considered in an analysis based on a consistent lateral displacement criterion? C. Evaluation of the capability of a foundation to transfer shear when waterproofing is used for a range of site conditions (soil sites with shear wave velocity of 1000 feet per second to hard rock)? D. The definition of dead load for uplift evaluations (floatation and seismic overturning), including the treatment of the stored volume of water in any pools? E. Detail explanation of how settlement (including potential effects of static or dynamic differential settlement) was considered. Evaluation and consideration of the effects of settlement on construction procedures. Evaluation of the allowable settlement (total and differential) that can be accommodated in the foundation/structures? F. The maximum toe pressure for base mat design under worst-case static and dynamic loads and its justification. G. The stiff and soft spots evaluation in the foundation soil to maximize the bending moments used in the design of the foundation mat. H. Description of the design details of critical
