Page 2 of 5 EECE EDM 06-55 2006-1092 STRUCTURAL COMMENTS General 2. EOR please submit design analysis for the glu-lam to account for the volume factor. The analysis just calculates the section required (Sr) required with account for the volume factor. Please resubmit analysis as required per NDS. NDS 5.3.6 Analysis for the glu-lam beams still has not dealt using the volume factor. Glu -lam depth over 12" shall be modified using the volume factor. Submit analysis for the glu-lam beams to account for the volume factor and not the depth factor as required per code. Please clearly submit analysis for the glu-lam beams to account for the volume factor as required per code. Sheet 3 MAIN FLOOR PLAN: 2. Design analysis does not match the drawings specified. For example the new analysis requires the beams in the garage to be larger then beams shown on this sheet. The drawings are required to match and all discrepancy should be corrected and resubmitted. Modify this sheet to match the requirements as shown on the structural sheets or delete all the structural information. 8. Drawing appears not to show how, the joist and double joist in the garage is connected to the supporting beams. Please clarify where this information's is specified. The response state see answer to number 1. It still is not clear on the drawings how these beam will be positively attached to the supporting structures. Please modify drawings clearly to show the requirements to transfer the design load forces. 4. .9. EOR please provide calculation for a continuous glu-lam beam. The maximum bending stress will be in the top lam and the allowable stress is 1850 and not 2400psi. Alternative specify the glu-lam shall be 24F -V8. NDS table 5A (Note the engineer package state to use 24F -V4) This still appears not to be addressed. IF all the beams are simple span beams this should be specified this way on the drawings. Glu -lam beams are manufactured members ant the top and bottom lams have different allowable bending stress if 24F -V4. This is the typical Glu -lam beams fabricated and used in Washington if not specifically stated. Please modify drawings accordingly. 10. Please specify the required post including the required connections that support the beams. For example the 5-1/8X9 at the living room. The drawings appear not to specify the required connections or the support. Please clarify on the drawing the required connections and support. This still has not been addressed. Page 3 of 5 EECE EDM 06-55 2006-1092 6. 11. EOR please specify the required connection of the 6X6 post column in the wall. All columns must have are required to have a positive connections specified to resist lateral displacement. IBC 23049.7 Response state this is standard construction and the connections is not required to be specified. The code is very specific that state all post shall be positively connected. Please add to the drawing the required post to beam connections as required. IBC 2304.9.7 7. 12. EOR or AOR please submit analysis of the beams in the garage. The locations of the columns are not specified so it is not clear the span in order to check capacity. Submit analysis for the beams and clearly dimension the post locations. Drawings do not match the new analysis submitted. Modify drawing to clearly show what is required. It should not be left up to the contractor to have to decide between 2 different beam sizes. 8. 14. Please specify the required for the continuous joist drag strut on the drawings. What is the required nailing in order to transfer the design forces? The drawings should clearly specify this. The drag strut nailing is required to be specified on the drawings. This is the collector element that is transferring the horizontal shear forces to the vertical resisting elements. This should be added to the drawings. Sheet 5 ROOF FRAMING PLAN: 9. 15. EOR please specify the required support of the girder truss. This also should include the connections. The truss manufactures typically does not specify this on the drawings. Currently the drawings do not have anything specified. The response no, is not an acceptable response. I called one truss manufacture in this area (Western wood Structures) and they stated typically the engineer has this clearly labeled on the drawings. They can do it but this need to be label as a deferred submittal as required per IBC 106.3.4.2. This also must be approved by the building official if elect to list this as a deferred submittal. The drawings are required to show the required connections as required per code. 10. 16. EOR please submits calculations for the 3-118 X22-112 spanning 32 feet. The response stating no is not an acceptable answer. Please modify accordingly 11. 19. EOR this sheet specifies different framing member to use then sheet FRI. Please clarify what is required for the construction of this structure. The structural information shown on this sheet should be clearly crossed out to assure what is built in the field is what is required per analysis. 12. 20. EOR please specify the required connection of the dbl 2x12 to the glu-lam beam. Nothing is specified at this time. This still has not been addressed. Please modify drawings accordingly. Page 4of5 EECE EDM 06-55 2006-1092 13. 21. EOR please specify the required post to support the DBL 2x12. This also should include the required connections. This still has not been addressed on the drawings. Sheet FR1 HIGH ROOF FRAMING: 14. 22. EOR please specify the required connection of the beams to the post. Nothing is specified at this time. This still has not been addressed. 15. 23. The drawings are not clear what supports the girder trusses. The drawings should clearly specify the support and the required connections. Please modify drawings in order to show the required connections. Truss manufacture typically does not deal with this but only design the truss and leave the supporting member to be specified by the design professional. The response that state emphatically no is not an acceptable response. Typically this is specified on the drawings. If elect to do this as a deferred submittal then should be labeled as such and get approval from the building official. 16. 24. Based off the roof layout the code defines this as having plan irregularities. The analysis has not dealt with this. Provide analysis for the L shape structure as required per code. IBC 1620.4.1 The response that states this only occurs when seismic controls are not correct. Both cases need to be checked. IBC 1620.4.1. In additions in the response it is stated the overstress is acceptable. The code does not allow any member to be overstressed. Modify drawings and analysis to show nothing is over stressed. Sheet FR2 LOW ROOF/2" FLOOR FRAMING: 17.26. Please specify the required 5-1/8X15 and 3-1/8X13 glu-lam beam. All that is called out is the reactions. A positive connection should be specified on the drawings not just the reactions. The response state the two glu-lath beams has been specified. All that is specified on the drawings is for the glu-lam beam to rest on the g 3-118. This is not a positive connection. Please add to the drawings the required positive connection to the drawings as required per code. Sheet FR3 FIRST FLOOR FRAMING: 18. 29. It is not clear based off the drawings where this is located. Please add grids or another way to clarify the framing locations. The drawings are not clear in order to check complete load path. Please modify drawing to match the architectural drawings. Response state see sheet FR1. But this still does not show where this is. Please modify drawings clearly to show where this applies. Page 5 of 5 EECE EDM 06-55 2006-1092 19. 31. EOR please specify the required members that are specified as DBL. Also specify the required connections. The response state the member has been changed but the connections is required to be added to the drawings. Also drawing still do not state that double means double joist. Please note this one the drawings. 20. 32. EOR please specify the required footing size. All that is noted is add post and footing. This sheet foundation does not match sheet 2. For example at the fireplace in the living room show different framing. Please modify the drawings clearly to show what is required to be built here. Some items are shown and then some items are not. It is not clear what will be built in the field. Modify the set to clearly show what is required to be built in order to complete the review. 21. 33. EOR please specify the required post to use. All that is noted is add post. The response state duplicated. The comment is not duplicated of 32. Please clearly add to the drawing the required post to support the floor framing. Sheet SL -2 SHEAR WALL CONNECTION DET.: 22, 37. Required roof diaphragm to shear wall connection: Please modify note that states (2) 2x maybe substituted for a 3X member. The code specifically states single 3x member shall be used. Also there is not a M2 detail as referenced. IBC 2305.3. 10 and table 2306.4.1 footnote i. This still has not been modified as per the response. Please modify drawings as required. Additional corrections may be required following receipt of corrections and additional information as requested. Your plans are being reviewed concurrently with the Building Department, Fire Department, Zoning Department and Public Works Engineering. Changes, clarifications or additional corrections may be required subsequent to the Building Department plan review when comments are received from the other concerned departments.
