Marcus Kim, P.E., Hana Engineers & Consultants, LLCCopy:Bill Brooks, P.E., EA Engineering, Science, and Technology, Inc., PBCDate:20 April 2018Re:Atlantic Wood Industries Containment Area No.2 – Design Analysis Report for ProposedConcrete Slabs for Steel Quads Forming Beds (Final)This technical memorandum summarizes the design analysis performed for the proposedconcrete slabs for the steel quads forming beds at the Atlantic Wood Industries (AWI) Containment AreaNo.2 project site.Assumptions1. Dimensions and forming bed layout for the proposed slabs were provided by Atlantic Metrocast,Inc. (AMI). Pictures of the current forming beds layout are attached.2. Unit weights (pounds per lineal foot) of the steel quads forming beds are as provided by AMI (seeattached email correspondence).3. AMI will install anchor bolts for the steel quads forming beds to the spacing and layout as neededfor their operations after the concrete slabs are constructed.4. Proposed slabs subgrade is assumed to be composed of VDOT 21A stone aggregates. No swellpotential is assumed for this subgrade material.5. Negligible settlement and differential settlement is assumed.Concrete Slab on Grade AnalysisAll equations and analysis methodologies summarized herein are in accordance with thefollowing references unless otherwise noted:1.

Middlebrooks, T.A. and Bertram, G.E., (1942), “Soil Tests for Design of Runway Pavements.”Highway Research Board Proceedings of Twenty-Second Annual Meeting, Vol.22.The dimensions used in the design analysis of each slab, number of steel quads forming beds andpre-cast and pre-stressed concrete piles are tabulated below. Note we assumed 4 piles per quad at thefull length of the slab.Slab 1Length(ft)445Slab 2405Slab #16Thickness(ft)0.5No. ofQuads2Pile Crosssection (ft2)1No. ofpiles8100.511.364Width (ft)The total load provided from the steel quads on Slabs 1 and 2 are 267,000 lbs and 137,700 lbs,respectively. The self-weight of the slab was calculated using an assumed unit weight of concrete of 150lb/ft3. Using the same unit weight, the total weight of the piles for each slab was derived. The totalweight per slab therefore included the weights of the steel quads, the self-weight of the slabs, and theweight of the piles. When converted to a total stress, the stresses at Slabs 1 and 2 were about 187.5 psfand 190.7 psf, respectively.The following was used as input data for the analysis.Slab Thickness, t (in)Concrete Strength, f 'c (psi)Subgrade Modulus, k (pci)Factor of Safety, FS Uniform Load, slab 1 (psf)Uniform Load, slab 2 (psf)6.040002002.0187.5190.7Using these design input data, the modulus of rupture (MR) is calculated below.𝑀𝑀𝑅𝑅 9 𝑓𝑓′𝑐𝑐MR was 569.21 psi. The allowable bending stress (Fb) was calculated by dividing MR by the factorof safety (FS). The allowable bending stress was determined to be 284.60 psi.The modulus of elasticity (Ec) was approximated as𝐸𝐸𝑐𝑐 57000 𝑓𝑓′𝑐𝑐The modulus of elasticity was therefore about 3,605 ksi. Using reference 1, the stationaryuniformly distributed loads was calculated using the equation 𝐴𝐴𝐴𝐴𝐴𝐴𝐴 ��𝑢𝑢𝑢𝑢𝑢 ��𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑 𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙 257.876 𝐹𝐹𝑏𝑏 𝑡𝑡 𝑘𝑘 𝐸𝐸𝑐𝑐Where t is the slab thickness. The total allowable stress was about 1,339 psf, which is higher thanthe applied stresses for Slabs 1 and 2 (187.5 psf and 190.7 psf, respectively).Hana Engineers and Consultants, LLC. 7501 Boulder View Drive Suite 620 Richmond, Virginia 23225 hanaengineers.comAR300773
The distributed loads was also calculated using reference 2 using the equation shown below,which resulted in a value of about 1,212 psf, which is considerable higher than the actual applieddistributed ���𝐴𝐴𝐴𝐴𝐴𝐴 ��𝑢𝑢𝑢𝑢𝑢 ��𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖𝑖 𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙 0.123 𝐹𝐹𝑏𝑏 𝑡𝑡 𝑘𝑘As a secondary check, we used the PCA procedure reported in ACI 360R (2006) for plain concreteslabs. Using the table below (Table 1) for a 6-inch slab, k 200 pci, working stress of 300 psi, an allowableload of 1,340 psf is estimated at the critical aisle width.Table 1. Allowable Distribution Loads, Unjointed Aisles, Uniform Loading, and Variable Layout; (Table A-1.4.2in Appendix A of ACI 360R)Since negligible moment and shear are applied to the slab on grade, the procedure outlined inSection 6.3 in Reference 3 is used to determine the amount of non-prestressed reinforcement neededas shrinkage and temperature reinforcement and to control crack widths. This reinforcement is notintended to serve as flexural reinforcement. The cross-sectional area in square inches of steel per linearfoot (As) is calculated using the equation below.Hana Engineers and Consultants, LLC. 7501 Boulder View Drive Suite 620 Richmond, Virginia 23225 hanaengineers.comAR300774
𝐴𝐴𝑠𝑠 𝐹𝐹 𝐿𝐿 𝑤𝑤2 𝑓𝑓𝑠𝑠Where F is the friction factor of 1.5, L is the distance between the free ends of the slab that canmove due to shrinkage or expansion, w is the dead weight of the slab in psf, and fs is the allowable stressin the reinforcement (2/3 of the yield strength reinforcing steel, fy). The yield strength of reinforcingsteel (fy) is 60,000 psi. The above equation resulted in As equal to 0.056 in2/ft and 0.036 in2/ft for Slabs1 and 2, respectively. Thus for slab reinforcement, we recommend using a 6x6 W4.0xW4.0 welded wirereinforcement. This reinforcement has an As of 0.080 in2/ft in the longitudinal and transverse directions,and has an approximate weight of 58 lbs per 100 ft2.PCA suggests the spacing between contraction joints between 12 and 18 feet for a 6-inch plainslab on grade. This range is a function of concrete slump and aggregate size. We recommend contractionjoint spacing of 15 feet, which corresponds to slump of about 4 inches and aggregate size equal to orgreater than ¾-in. The joint groove should be 1.5-inches deep, which corresponds to about ¼ thethickness of the slab. Conventional saw-cut joints are typically run within 4 to 12 hours after the concretehas been finished.AMI is responsible for the installation of quads forming beds to the slabs. It is our understandingthe quads forming beds will be fastened to the slabs via anchor bolts that will be drilled and grouted intothe slab. We don’t foresee any negative impact to the overall performance and the life-span of the slabsresulting from these anticipated activities associated with installing the quads forming beds to the slab.Attachments:-Pictures of AMI’s current steel quads forming beds.Email correspondence from AMI regarding steel quads forming bed weights, dated March 7,2016.Hana Engineers and Consultants, LLC. 7501 Boulder View Drive Suite 620 Richmond, Virginia 23225 hanaengineers.comAR300775
