Page 2 of 4 EECE#: EDM 06-62 Walcher Residence STRUCTURAL COMMENTS General 3. EOR please provide calculation for the slab to resist 7.5 kip force at the base as noted in the Enercalc program. 4. Please reference the location of each different wall type to use throughout this structure. Sheet S 1 and S2 have many different cases for retaining wall to be built. It is not clear where all the locations of these walls are to be used. This should not be decided by the contractor but should be clearly referenced on the drawings. Sheet A2 BASEMENT PLAN SHOWING 2ND FLOOR FRAMING: 5. EOR please clearly specify the required connections for the post to the beams. 6. EOR please specify the required connection of the post that bears on the supporting beam below. I was unable to determine the required connections for the drawings. Sheet A3 FLOOR PLAN 2ND LEVEL: 7. EOR please clearly specify the required connections for the post to the beams. This also should include the double joist. Sheet A4 2ND FLOOR SHOWING 3RD FLOOR FRAMING: 8. EOR please clearly specify the required connections for the post to the beams. This also should include the double joist. Sheet A5 FLOOR PLAN 3RD LEVEL: 9. Please clarify on the drawing how the shear force from the roof framing is transferred to the interior shear wall. Sheet A7 does not show how these walls are framing to transfer this force. Please add detail and collector elements to transfer the required lateral forces. IBC 1620.2.6 Sheet A7 ROOF FRAMING PLAN: 10. EOR please provide analysis for the horizontal diaphragm nailing requirements. It appears the nailing specified in note 2 will not support the required horizontal diaphragm forces for an unblocked diaphragm. IBC 1620.2.5 and IBC 1620.4.3 Page 3 of 4 EECE#. EDM 06-62 Walcher Residence SheetA8 CONSTRUCTION DETAILS: 11. Detail 10: EOR please provide analysis for the deck guard rail including the connections required. 12. Detail 12: EOR please specify the required stair angle bolted to floor beam to resist the design forces. All that is noted is the following, "STAIR < BOLTED TO FLOOR BEAM SIMPSON". Sheet A9 CONSTRUCTION DETAILS: 13, Detail 5: Please clarify note "RAILING DETAIL SEE SHEET A". It is not clear the required connection required at this location. Also this connection should resist the minimum code required forces of 200 pounds applied in any direction. R301.5 14. Detail 7: Please clarify in the detail what the '/z diameter ledger bolts are connecting to the main structure. All that is noted is building line. Without this information there is no way to check the connection to support the minimum code design loads. IBC 106.3.3 Sheet S 1 STRUCTURAL DETAILS: 15. Detail A2: Design analysis used a height to design the retaining wall to be 19 feet but the detail states 19'6" max. Modify analysis to match the detail that will be built or modify the detail to be in compliance with analysis. IBC 1604.4 16. Detail A2: Design analysis used a d for the top stem wall to be 3.69 inches. With a 2" clear and center of reinforcement the d from the compression face of concrete to center of tension steel shall be 3.18 and not 3.69. Please modify the analysis or the drawings to resist the design force as required. ACI chapter 10: (d= distance from the extreme compression fiber to the centroid of tension reinforcement.) Also note the program output picture clearly states the center of steel to the compression face to be 1-314" but the drawings show 2" clear. 17. Detail Al and A2: Please specify the required length of the #5 @ 10" OIC reinforcement at the top of the footing. 18. EOR please provide analysis for detail Al. The submitted analysis does not appear to have this wall designed. Page 4 of 4 EECE#: EDM 06-62 Walcher Residence 19. Detail 4: EOR provide analysis for the A34 to resist the horizontal force form the soil pressure as a restrained wail. The maximum force and A34 can resist with a force applied perpendicular is 345 pounds. Therefore (2) A34 can only resist 690 pounds if the joist were spaced at 12" OIC. Also the bolts spaced at 8" OIC do not resist this force. Note per table I IE Z perpendicular to plane is 470 pounds per foot. So the for the maximum force that can be resisted is 705 pounds. But it is clear in the analysis the required force the top of the wall is required to resist is 1.1 kips. Modify detail accordingly. NDS 11.3 20. Detail 4: When the joist run parallel to the wall the blocking at 24" OIC will not resist the design force. Please modify accordingly. NDS table 11E. 21. Detail 4: EOR submit analysis to account for the 100 psf force required for the restrained wall. All the analysis submitted has stated the wall is free to rotate at the top. This is not the case for the restrained wall. 22. EOR please submit analysis for straight bar embedment of the dowel to resist the design force. It appears the analysis is counting on this bar to transfer this force. Please clarify on the response. 23. Detail 4: EOR submit analysis for the 18" wide footing to support the vertical loads with out exceeding the allowable bearing pressure. This must include the weight of concrete and the floor loads above. The maximum force that can be resisted vertically is 2500 PSF * 18" wide footing * 12" per foot = 3750 pound per foot of wall. Just the weight of wall alone has a vertical force of 150*11 feet*8 inch wall/12 =1100 pounds per foot. IBC 1801.2 Sheet S2 STRUCTURAL DETAILS: 24. Detail 4: EOR please modify the test under the toe to read the required length for the 9'6" wall. 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. Should you have any inquiries regarding this letter, please contact Hoyt Jeter at (360) 874-0562 between 5:00 a.m. and 5:00 p.m. By: Hoyt Jeter, P.E.
