5. The structure appears to an in-plane vertical irregularity of the lateral force resisting system. Per ASCE 7-10 Sec 12.3.3.4, having this type of irregularity requires an increase of 25% to design demands related to connections of diaphragms and collectors to the vertical lateral force resisting system. 6. In the direction where the moment frames are taking direct shear, please demonstrate how the redundancy factor, p, is 1.0 as it appears that the removal two connections in a single beam would render the moment frame unable to resist lateral forces and place cL the full shear demand on one line of plywood shear walls. Please clarify or provide a redundancy factor of 1.3 at this level where required. 7. It appears that the overall height of the structure is greater than 30'-0". Please demonstrate that a Type 5b vertical irregularity is not present in the structure per Sec 12.3.3.2 of ASCE 7-10. 8. Per ASIC 341-10, the use of an ordinary steel moment frame requires the design of fully restrained or partially restrained moment connections per El, Item 6. Please indicate which types of connections are provided for the moment frame connections and provide calculations supporting the design assumptions. Please revise details as required. 9. Please provide checks for uplift as it does not appear to accounted for in the design of the footings. wh, 6e,1 , ? 10. It appears that the steel moment frame beams are conflicting with the glu-lam beams indicated on Sheet 2.1 of the architectural drawings. Please clarify beam locations. 11. On Detail F of Sheet 7 of the architectural drawings, please provide a design calculation for the guardrail connections to the new deck in accordance with IBC 2015 Sec 1607.8. Details should be provided on the plans.
