Koehn DATE:8/29/17 REVIEWED BY: Richard D. Luark DATE: 8/30/17 ATTACHED ARE THE SOIL NAIL CALCULATIONS FOR THE REDESIGN OF THE SOUTH WALL AS PER THE UPDATED GRADING PLANS FOR THE MARRIOT RESIDENCE INN LOCATED IN RENTON, WASHINGTON. THE FOLLOWING CALCULATIONS ARE ATTACHED: •SOIL NAILS •SHOTCRETE FACING PROJECT: Renton MRI PROJECT NO.: 81155060 TASK: 5 SUBJECT: South Wall Redesign BY: Zachary L. Koehn DATE: 8/29/17 REVIEWED BY: Richard D. Luark DATE: 8/30/17 Page 1 of 3 PURPOSE: Re-design south permanent soil nail wall as per revised grading plan. GIVEN: Soil Parameters: Soil Unit Moist Unit Weight (pcf) Friction (deg) Cohesion (psf) Ultimate Pull Out Resistance (k/ft) Med. Dense Granular 125 34 0 4 V. Dense ML/SM 125 32 550 4 V. Dense Sand 120 38 0 4 Reference: “Updated Geotechnical Engineering Study Marriott Residence Inn Proposed Hotel Facility Renton, Washington” dated April 21, 2015, by Earth Solutions NW LLC. Reference: “Shoring and Permanent Soil Nail Retaining Wall. Design Drawings and Specifications, Permit Submittal” dated November 25, 2015, by Terracon, Inc. Geometry:Original backgrounds supplied by the Jenson Fey Architects based on the 50% DD set. The structural foundation plans were from DCI Engineers, progress set dated 11/2/15. Updated backgrounds supplied by Barghausen Consulting Engineers, Inc. revised per City of Renton comments and 1:1 cut slope dated 7/27/17. Shoring designed for excavation depth down to the base of the footing although the shotcrete facing will only extend down to the top of the footing along the perimeter of the building. Were the free standing permanent soil nail wall is present, the temporary shotcrete facing will extend down to the base of the footing which is 2-feet below finished grade in front of the wall. Horizontal soil nail spacing is 6 feet on center. Maximum vertical spacing is 6-feet on center. Materials:75 ksi threaded tendons in standard bar sizes (#7, #8 & #9). Epoxy coated tendons for the permanent soil nail wall to provide double corrosion protection. Use 3,000 psi UCS grout for nails + 4,000 psi UCS for shotcrete. Factor of Safety on Soils: Minimum factors of safety of 1.5 for static, 1.1 for seismic,1.2 for interim temporary stability, and soil nail pull out for static of 2.0 and 1.5 for seismic. Seismic Design: Peak ground acceleration is 0.597g based on USGS website for the IBC design earthquake adjust for site class C soil profile. Permanent south wall designed with a pseudo static coefficient equal to ½ of the PGA which equals 0.3. ASSUMPTIONS: No construction surcharges on the slope during soil nail construction. Fill placement will be completed prior to installation of soil nails. Construction surcharges of up to 500 psf vertical are allowed above the south permanent soil nail wall as the permanent walls are designed for seismic, which controls the design and can withstand up to a 500 psf construction surcharge for the temporary condition. Seismic can be ignored as temporary condition. Material factors: 0.66 on head strength; 0.55 on tendons for both temporary and permanent soil nail walls. PROJECT: Renton MRI PROJECT NO.: 81155060 TASK: 5 SUBJECT: South Wall Redesign BY: Zachary L. Koehn DATE: 8/29/17 REVIEWED BY: Richard D. Luark DATE: 8/30/17 Page 2 of 3 Where structural fill is used to backfill, the fill will have material properties equal to that of medium dense granular soils (friction angle = 34 degrees, cohesion = 0, and unit weight = 125 pcf). Maximum deflection at top of soil nail wall is on the order of 1-inch or less for temporary and static conditions. Maximum permanent displacement of the permanent soil nail wall in response to the design seismic event is 1-inch or less. ANALYSIS: Use Snail version 2.0.3.1 to size soil nails using factored resistance (head strength, tendon and pullout). RESULTS: The following summarizes the results for the soil nail analysis. H includes the footing excavation depth (which is to the based on the perimeter footing excavation; however where the soil nail wall is adjacent to footing excavations, the facing will only extend down to the top of the footings). T The Snail outputs are attached. Maximum vertical spacing of soil nails is 6 foot on center. Schedule #2 – Excavation Height = 30.5 ft Row L (ft)Bar Vert.
