BUSH GENERAL MANAGER JOSELYN GEAGA-ROSENTHAL GEORGE HOVAGUIMIAN JAVIER NUNEZ ERIC GARCETTI MAYOR OSAMA YOUNAN, P.E. EXECUTIVE OFFICER Simpson Strong-Tie Company, Inc. RESEARCH REPORT: RR Holly Street (CSI# 06121) Riverside, CA BASED UPON ICC-ES EVALUATION Attn: Tim Kaucher, P.E. REPORT NO. ESR-1679 (714) REEVALUATION DUE DATE: August 1, 2018 Issued Date: December 1, 2016 Code: 2014 LABC GENERAL APPROVAL Reevaluation and Technical Modification - SSW Shear Panels and S/SSW Shear Panels DETAILS The above assemblies and/or products are approved when in compliance with the use, description, design, installation, conditions of approval, and identification of Evaluation Report No. ESR-1679, reissued June 1, 2015, revised April, 2016 of the ICC Evaluation Service, LLC. The report, in its entirety, is attached and made part of this general approval. The parts of Report No.ESR-1679 marked by the asterisks are the parts modified by the Los Angeles Building Department from this approval. The approval is subject to the following conditions: 1. The allowable loads shall be determined by calculations prepared by an engineer or architect licensed in the state of California and approved by the structural plan check. When evaluating top-of-wall drift, the drift contributed by anchor bolt elongation and grade beam or foundation rotation shall be taken into consideration. 2. The engineer of record shall check the uplift force and hold-down anchor bolt capacity in accordance with the 2014 Los Angles City Building Code based on edge distance, end distance and embedment depth detailed on plans.

2 Simpson Strong-Tie Company, Inc. Re: SSW Shear Panels and S/SSW Shear Panels 3. Continuous inspection by Deputy Inspectors shall be provided during installations of hold-down anchor bolts prior to pouring concrete. 4. Fabrication of SSW Shear Panels and S/SSW Shear Panels shall be in a shop of a fabricator licensed by the City of Los Angeles Building Department, in accordance with the Manufacturing Standards submitted to the Department. 5. A manufactured narrow shear panel is any product that is delivered assembled to a construction site for installation within a building and which does not conform to the design aspect ratio requirement stated in Table of the ANSI/AF&PA SDPWS-08. Narrow Shear Panels shall comply with the following conditions: a. The panel can be installed on the first (lowest) story of light-framed construction directly on a concrete wall without mud sill or cripple wall, in balloon framing condition, on a first floor wood raised floor, and on second floor. b. All installations shall use the respective manufacturer s approved anchor bolt template, and otherwise be installed per the approved manufacturer s installation instructions and specifications. c. Design of the system shall be considered light-frame walls sheathed with wood structural panels rated for shear resistance or steel sheets with R=6.5 in the direction considered. When panels are used in line with other types of panels, only one type shall be considered as the lateral resistance element. 6. When designing with SSW Shear Panels and S/SSW Shear Panels the engineer of the record shall check: a. The concrete capacity of hold-down bolts for overturning, compression and tension. b. The allowable vertical load on header. c. The hold-down bolt capacity based on edge and end distances as detailed on the plans when using anchorage details other than shown in this report. d. For grade beam applications the engineer of record shall ensure: i. Closed-tie anchor reinforcement is used for grade beam design. ii. iii. Plastic hinging is prevented at anchor locations in seismic applications. Factored anchor demand for wind and amplified anchor demand for seismic applications are to be applied for grade beam design.

3 Simpson Strong-Tie Company, Inc. Re: SSW Shear Panels and S/SSW Shear Panels DISCUSSION The technical modification is to add Steel Strong-Wall anchorage for grade beam applications to the report. The report is in compliance with the 2014 Los Angeles City Building Code. The approved conditions are based on Information Bulletin P/BC Interim Policy on Manufactured Narrow Shear Panels. The approval is based on load tests and analyses in accordance with the ICC-ES Acceptance Criteria for Prefabricated, Cold-formed, Steel Lateral-force-resisting Vertical Assemblies (AC322), dated January 2013 (editorially revised February 2015) and Chapters 19,22 and 23 of the applicable code. This general approval of an equivalent alternate to the Code is only valid where an engineer and/or inspector of this Department has determined that all conditions of this approval have been met in the project in which it is to be used. Addressee to whom this Research Report is issued is responsible for providing copies of it, complete with any attachments indicated, to architects, engineers and builders using items approved herein in design or construction which must be approved by Department of Building and Safety Engineers and Inspectors. This general approval will remain effective provided the Evaluation Report is maintained valid and unrevised with the issuing organization. Any revisions to the report must be submitted to this Department, with appropriate fee, for review in order to continue the approval of the revised report.
