V xx 2.612 k (0.03+0.04)'5.33`14/2 row 430 V allowable 9.08 k V allowable=9.08 k > V required=2.61 k OK The formula for horizontal shear is v=3/2 V/(b h) f. The notch is not in a region considered to resist horizontal shear but,if it was, 1/2 of the beam depth would still resist the horizontal shear where V allowable=4.44 k>2.612 k required. Also, notch corners are round which reduces stress concentrations. It is my opinion that beams as notched are OK. gr. .„ }k '. row 460 Outlook.com Print Message Page 1 of 5 bracket modification i r;}i Peter(jpalouw@hotmail.com) c. m: Fri 3/13/15 6:04 PM ice.or @comcast.net(ice.or @comcast.net) Peter(jpalouw @hotmail.com) Hi Craig, Re: my storage room, ,; RN 6 t i s t_ -1 eli1 https://bay 174.mail.live.com/ol/mail.mvc/PrintMessages?mkt=en-us 3/21/2015 Outlook.com Print Message Page 2 of 5 y sr t • r 1 V e ■ ''Aa, - on • i_ _ lit ,. _ . . .. q Si x. 1 T ■f la' r , ,,.,,,,, 4 I i f j t https://bay 174.mail.live.com/ol/mail.mvc/PrintMessages?mkt=en-us 3/21/2015 Outlook.com Print Message Page 3 of 5 • 1Y , r• Ong i. - 4 a 3, M u` w f �J tl https://bay 174.mail.live.com/ol/mail.mvc/PrintMessages?mkt=en-us 3/21/2015 Outlook.com Print Message Page 4 of 5 • R .4T ' i L.

Thought the gas line was loose enough to move out of the way but it wasn't so I had to notch the brackets a bit. When I had the framing inspection he said he couldn't approve it with any changes to the bracket unless you, my structural engineer, can write a letter saying the modifications will not affect the structural integrity of the building. I've attached pictures of both sides of each bracket so you can see the notches I cut. All of the specified SDS screws remain secured into the beam and I added 4ea-4" SDS screws to fasten the existing floor joist to each beam to augment the attachments to the existing sill plate. I don't think I've compromised the structural integrity of the building and hope you will agree with me. If you can put it in writing that the notches in the column caps will not affect the structural integrity of the storage room it will save me a lot of hassle. https://bay 174.mail.live.com/ol/mail.mvc/PrintMessages?mkt=en-us 3/21/2015
