Mr. Sanjeev Sharma Z Realty Plus Plan Check Number: B2006-012, Second Building Review October 20, 2020 Lateral System: This comment has not been addressed; the original comment is provided below. The response states that revised calculations have been provided demonstrating compliance. However, the calculations do not appear to include the required seismic loading. See revised calculation pages B13 and B19 for Beams 4 and 6, respectively, as examples. These beams do not include seismic loads. This comment is not limited to these two beams; all framing (e.g., beams, posts, columns, connections, etc.) supporting discontinuous shear walls should be evaluated and modified as needed. The building includes multiple shear walls that are not continuous to the foundation and are partially or completely supported by beams and posts. This is a Type 4 Vertical Structural Irregularity per ASCE 7-10 Table 12.3-2. The framing supporting the walls and the connections between the walls and framing, connections interconnecting the supporting framing, and connections to the foundations, should be designed including overstrength per Section 12.3.3.3. This includes most of the framing supporting shear walls at the Upper Floor. The load combination of Section 12.4.3.2 including vertical effects per Section 12.4.2.2 should be used. Calculations substantiating the design should be submitted for review. Additional Comments: The garage foundation at Grid D/1-5 on Sheet S4 includes a combination of standard shallow footings and thickened slab. The structural details do not appear to provide a thickened slab detail. The plan does not indicate where the transitions between the two foundation types occur. Note that the foundations support wall and post loads from above. Reference Architectural Comments 4 and 5 related to this issue. The foundation design should be revised as needed. See IBC Section 107.2.1 and 1603.1. This review has been performed for general compliance with the building codes as adopted and amended by the state of Washington and the city of Everett. Corrections and comments made during the review process do not relieve the project from compliance with code and permit requirements. The designers -of -record are responsible for a complete design in accordance with the laws of the state of Washington.
