• <br /> • <br /> Ms. Jessica Bradley <br /> Nelson Worldwide <br /> Plan Check Number: B1909-009, First Building Review <br /> September 27, 2019 <br /> 12.11.2.1; ka per Equation 12.11-2 shall consider the diaphragm span between supporting <br /> walls, not the width of the modifications or the spacing of the girts. The roof diaphragm shall <br /> be modified to provide subdiaphragms as needed to develop the connection load into the <br /> diaphragm. See IBC Sections 1604.1, 1604.4, and 1613.1. <br /> 4. Section 2/S1.1 shows the typical girt connections to the existing concrete wall panels utilizing <br /> expansion anchors. See IBC Section 107.2.1. The following comments shall be addressed: <br /> a. The connection design is based on a minimum panel edge distance of 7-1/2 inches. This <br /> distance shall be specified. <br /> b. The section specifies a minimum embedment of 4-1/2 inches. This is the effective depth <br /> after installation and tightening. However, the nominal anchor depth (i.e., minimum hole <br /> depth and anchor length prior to tightening) per the calculations is 5-1/8 inches. The <br /> required embedment shall be clarified to ensure the proper depth is achieved. <br /> 5. Section 3/S1.1 shows the typical connection between orthogonal wall panels. Calculations <br /> substantiating the connection do not appear to be included in the calculation package and shall <br /> be submitted for review. Note that the connection will induce eccentric loads in the anchors. <br /> The anchors shall be designed for concurrent shear and tensile loading. See IBC Sections <br /> 1604.1 and 1604.4. <br /> This review has been performed for general compliance with the building codes as adopted and <br /> amended by the state of Washington and the city of Everett. Corrections and comments made <br /> during the review process do not relieve the project from compliance with code and permit <br /> requirements. The designers-of-record are responsible for a complete design in accordance with <br /> the laws of the state of Washington. <br /> If you have any questions or require additional clarification, please contact us. <br /> Respectfully, <br /> Drew Martin, P.E., S.E. <br /> Associate Engineer/Commercial Plans Examiner <br /> (425)257-8813 <br /> dmartin@everettwa.gov <br /> S:\BMartin\2019\B1909-009_R1.docx <br /> 0 03200 Cedar Street 0 425.257.8810 r", everetteps@everettwa.gov <br /> Everett,WA 98201 425.257.8857 fax everettwa.gov/permits <br /> Page 5 of 5 <br />
