Project: Bethany At Silver Crest By: LW ISheet No. Location: Everett, WA Date: 11/11/20 1 ES-1 Client: ThermalRite Revised: lJob No. Subject: Walk -In Cooler/ Freezer Analysis Date: 12000618 EXECUTIVE SUMMARY PROJECT INFORMATION Client: ThermalRite Walk -In Coolers and Freezers 15600 37th Avenue N, Suite 100 Plymouth, MN 55446 Client Job No: E014869 Project Owner: Bethany At Silver Crest Project Location: Everett, WA Interior or Exterior: Exterior Total Number of Units: 1 Building Risk Category: II Storage Rack Anchorage: None DESIGN APPROACH The following calculations cover the design and connections for pre -manufactured refrigeration panels used to form interior or exterior walk-in coolers and freezers. The panels consist of minimum 26 gage galvanized steel, stainless steel, or aluminum skins with wood or high density foam framed perimeters with a foam core. The panels come in 3%", 4", and 5" thicknesses and are joined together with cam -lock fasteners. The panel capacities to support gravity loads and resist lateral forces have been determined through testing and applicable tables have been provided in the calculations showing the results. The following calculations utilize a flexible diaphragm analysis in order to distribute the lateral forces through the roof diaphragm to the wall panels which act as structural shear walls. Seismic forces have been determined in accordance with ASCE7 and wind forces have been determined in accordance with the ASCE 7 Chapter 28 — Wind Loads on Buildings — MWFRS (Envelope Procedure). Connections of the wall panels to the existing structure shall be in accordance with manufacturer's requirements for the specified anchors. BASIS OF DESIGN Applicable Building Code: 2018 International Building Code (2018 IBC) and Latest Revisions Design Loads Based On: ASCE 7-16 Minimum Design Loads for Buildings and Other Structure Seismic Analysis Based On: Equivalent Lateral Force Procedure Component Capacity Based On: Los Angeles Research Report No. 24543 (LARR 24543) DESIGN ASSUMPTIONS 1. Anchorage details provided are subject to site verification of the existing conditions. Minimum requirements specified in the details are to be verified by the Owner prior to installation. Where the specified minimums cannot be met, alternate anchorage details need to be specified by a Licensed Professional Engineer. 2. Post installed anchors require Special Inspection per Section 1701.1 of the applicable Building Code 3. The verification of the existing structure to support the new walk-ins shall be performed by others. This includes, but is not limited to, elevated floor framing, connections, slab -on -grade, and other foundation elements. 4. The verification of the existing soils to support the new walk-ins shall be performed by others 5. It is assumed that the existing slab is at least 4" thick normal weight concrete (NWC), with an fc equal to or greater than 2,500 psi.
