Iizuna Cider February 25,2019 <br /> Comment Response Page 2 of 2 <br /> c. The analysis shall consider the full weight of the mechanical unit unless the reduced <br /> tributary load is substantiated. <br /> The full weight of the mechanical unit is supported by(2)new 6 X 8 beams which span <br /> between the existing 5-1/8"X 16-1/2"GLB's running north-south.Thus,the full weight of <br /> the mechanical unit was divided by(4)support points for the analysis of the 5-1/8"X 16- <br /> 1/2"GLB's.In the analysis of the 6-3/4"X 27"GLB,the reactions from the 5-1/8"X 16-1/2" <br /> GLB's with and without the mechanical unit were compared to determine the additional <br /> load from the full weight of the mechanical unit. <br /> d. The analysis shall explicitly evaluate the negative bending moment in the beam considering <br /> the full loads on both spans to maximize the moment. <br /> Refer to the supplemental calculations dated 02/25/19 for the negative bending moment <br /> analysis of the 6-3/4"X 27"GLB. <br /> e. Continuing with the previous comment,the analysis shall consider the concentrated loads at <br /> the end of the cantilever span from the adjacent existing 31.5"glulam. These do not appear <br /> to be considered in the calculations. <br /> The reaction from the adjacent existing 31-1/2"deep GLB on the end of the cantilever of <br /> the 6-3/4"X 27"GIB is included in the supplemental calculations dated 02/25/19. <br /> If you have any questions or comments regarding the responses to this review, please do not hesitate to <br /> call. <br /> Sincerely, <br /> CG Engineering <br /> 9ae <br /> Mike Maechler, PE,SE <br /> Project Manager <br /> (7;/- <br /> O 250 4th Avenue South,Suite 200 <br /> Edmonds,WA 98020 <br /> ENGINEERING ph.425.778.8500 I f.425.778.5536 <br /> www.cgengineering.com <br />
