The following comments, deficiencies/corrections must be addressed prior to completion of plans review and subsequent issuance of permits. Provide revised plans and calculations along with a written response to each of the items listed below to facilitate a shorter back -check time. SCOPE OF REVIEW The scope of this review is for the Structural requirements of this project. All features were checked only to the extent allowed by the submittals provided. All portions of this project are assumed to meet or will meet other departmental requirements, conditions and concerns before permit approval. Page 2 of 4 EECE#: EDM 06-49 Thatcher Residence STRUCTURAL COMMENTS Sheet A-6 FOLTNDATION PLAN & DETAILS: 1. EOR please specify the required connection of the post on the exterior of the structure. The post is a 6x6 and the footing is a 24X24 but the connection appear not to be specified. 2. AOR please specify the required connection of the 4X12 that frame into the wall. Nothing is called out at this time. 3. Provide calculation to justify the 16" spread footing is able to support the reaction for the post supporting the 4X12 at the end wall. A larger footing is required at these locations. It is fine to assume the force will distribute when the post is supported at the center of the wall continuous footing. But when it frames into the end the force will not distribute down the length of the continuous wall footing. Please modify footing or justify not required by analysis. Sheet A-7 FLOOR FRAMING PLAN & DETAILS 4. Shearwall schedule: Please modify note 3 to state single 3X member is required not double 2X. IBC 2305.3.10 5. Shearwall Schedule: Please modify note 7 to state only 3X member required. The code specifically state single 3x is required. IBC 2306.4.1 footnote i. 6. Shearwall Schedule: SW4: Please note that the framing member shall be 3x member and the nails shall be staggered. IBC 2306.4.1 footnote e. 7. Shearwall schedule: Please modify note 8 to state where 3X member shall be required at the sill plate. IBC 2305.3.10 8. Drawings state hanger (MIIU1.81/11) that will not support the design loads. Also the span on the drawings appears to exceed the 5 foot design length. Please modify accordingly. Simpson design catalog C2005. 9. Please add to the drawing the required connection of the post to the beams. All post are required to be attached positively to resist lateral and induce uplift. Please modify the drawing to show this. IBC 2304.9.7 10. The drawing do not show any connections for the girder truss to the post specified. Please add this information to the drawings. 11. EOR please specify the required beam located at SW3 line. The roof plan does not specify these beams. Page 3 of 4 EECE#: EDM 06-49 Thatcher Residence 12. By definition the horizontal diaphragm would be classified as having discontinuity. What keeps the wings from tearing at these locations? Please either add positive connections to tie the diaphragm together or clarify on the drawing how these forces will be transferred. IBC 1620.2.2 IBC 1620.4.1 13. It appears based off the drawings beam number 10 exceed the design length of 5 feet. Please modify analysis and drawings accordingly. 14. Per definition the diaphragm maximum length to width appear to exceed the code maximum diaphragm dimensions ratios. Please modify accordingly. Table 2305.2.3 15. EOR please clarify the beam size and column connections at the covered nook entry. Sheet A-8 UPPER ROOF FRAMING PLAN & DETAILS: 16. EOR please clarify the load path for the support of the Column number 1. Based off the lower floor the column appears not to be supported. The plywood framing will not support the design loads. Please modify drawings accordingly to complete the load path to the foundations. 17. EOR please specify the required connection of the wood column on the drawing to transfer the required forces. Currently the drawings do not specify any connection in order to check capacity. For example the intersection of beam mark 2 and beam mark 1. 18. EOR please clarify how the loads were determined for beam mark 1. It appears the beam only took loads from one side and is only half loads. It appears the beam is not design with all the loads that are required for this beam. Please clarify on the response. 19. EOR please specify the required posts that are to support the girder truss. This also should include the required connections. Sheet A-9 DETAILS: 20. Detail 4: Please modify this detail to clearly note 90 degree hook into the footing. R403.1.3 21. Detail 2: Please clarify the section cut that state 16/A9. This appears not to be the correct reference. Please modify accordingly. Additional corrections may be required following receipt of corrections and additional information as requested.
