• • <br /> Ms. Finsch <br /> Tiscareno Associates <br /> Plan Check Number: B1801-032, First Review <br /> March 13, 2018 <br /> a. Calculations substantiating the design loads and capacities of the collectors and <br /> connections should be submitted for review. See IBC Section 1604.1. <br /> b. The design loads shall be based on a torsional analysis per APA SDPWS-15 Section 4252 <br /> Item 3 as discussed in other comments. <br /> c. The design loads shall be increases per ASCE 7-10 Section 12.3.3.4 as discussed in other <br /> comments in this letter. <br /> d. The framing and connections shall consider concurrent loading with gravity loads per the <br /> load combinations of IBC Section 1605.3.1. <br /> e. The hardware and nailing for the straps should be specified in the structural plans. <br /> 45.The Level 4 shear walls at Grid S-B per Sheets S210a-SS and S210b-SS do not align with the <br /> Level 4 shear walls per Sheets S209a-SS and S209b-SS. The results in a Type 4 Vertical <br /> Structural Irregularity per ASCE 7-10 Table 12.3-2. The framing supporting the shear walls <br /> shall satisfy the requirements of ASCE 7-10 Section 12.3.3.3. This shall include design for <br /> uplift. All elements and connections shall be evaluated in the load path to the foundation. See <br /> IBC Section 1613.1. <br /> Miscellaneous: <br /> 46. Level 4 includes walls and railings along Grid S-A on Sheets S210a and S210b, including wall <br /> returns at each of the structure. It appears that Sections 3/S502 and 4/S502 apply to this <br /> location and should be referenced on the plans. Calculations for the walls should be submitted <br /> for review. The design should also evaluate framing supporting the connection of <br /> prefabricated wall systems. See IBC Sections 1604.1, 1607.8.1, 1609.1.1, and 1613.1. <br /> 47. Details for the elevator support framing and connections of the elevator rails to the structure <br /> are provided on Sheet S403. The following comments should be addressed: <br /> a. The elevator design drawings should be included in the list of deferred submittals in the <br /> Structural General Notes on Sheet S001. See IBC Section 107.3.4.1. <br /> b. The design loads for the elevator system, including impact loading, should be specified in <br /> the"Design Criteria and Loads"section of the Structural General Notes on Sheet S001. At <br /> a minimum, estimated design loads should be specified for the design, and verified when <br /> the elevator design drawings are submitted for review. See IBC Sections 1603.1.8 and <br /> 1607.9.1. <br /> c. Multiple details show columns that do not appear in the structural plans. The plans should <br /> be revised to show the locations and sizes of the columns. See IBC Section 1603.1. <br /> d. The details generally do not appear to be referenced in the structural plans. References <br /> should be provided so that a review of the details may be completed. See IBC Section <br /> 107.2.1. <br /> e. Calculations for the elevator connections to the structural framing in Detail 6/S403 should <br /> be provided for review. The design shall consider concurrent multi-directional loading as <br /> determined by the elevator manufacturer. The maximum spacing for the connection points <br /> should be identified in the structural drawings. See IBC Section 107.2.1 and 1604.4. <br /> Page 10 of 11 <br /> CITY OF EVERETT• 3200 Cedar Street • Everett, WA 98201 • (425) 257-8810 • Fax(425) 257-8857 <br />
