Factored Lifting Load (P LF ) = DL + LL + Snow Load + Soil Load + Uncertainty Factor (Choose 15%)Factored Lifting Load (P LF ) = (2,200+750+150) + 2,950 lb/ft = 6,050 lb/ft + 908 lb/lf(15% of 6,050 lb/ft)Factored Lifting Load (P LF ) = 6,958 lb/lin.ft.(Use 7,000 lb./lin.ft.)End Design Example 1AReview of Results of Design Examples 1 & 1AOne can see that the result obtained by the Quick-Solveanalysis underestimated the foundation load by 3%compared to the more thorough weight analysis.Caution must be taken when using the Quick-Solvedesignmethod because the load estimates are based upon where the designer believes the structural weight falls withinthe ranges provided.Choices made in this example were in the middle range.It is quite evident that thisstructure is more robust than average construction.In the future for similar structures the loads should be selectednearertothe higherendoftherangesinthetableand/orincreasethepercentageusedfortheFactorofUncertainty in the weight estimate.ECP Technical Design Manual Steel Pier Design Examples2021 Earth Contact Products, L.L.C.2021-09 Chapter 7 - Page 134 All rights reserved'
