Can dome one give me a hint on how to handle a large opening in a wood diaphragm. See attached sketch,http://files.engineering.com/getfile.aspx?folder=a12ccfd1-ab7d-4717-91c0-54851b2f46f6&file=opening_in_flor_diaphragm.pdf

The attached sketch indicates what we mean by a coot age roof. It is of calked ( incorrectly) a hip roof.http://files.engineering.com/getfile.aspx?folder=842b176c-b36f-4f27-9f32-aeb728cf2c54&file=cottage_roof.pdf

Yes There are 2 hip rafters at each end of a cottage roof.

Could someone tell mw if there is any change needed to the normal procedure to design the roof diaphragm to a cottage style roof. I'm thinking not but not certain. The building would ne 62 x 110. Thanks kindly

Thanks to all for taking the time to put your thoughts to paper. It gives me some ammunition to form my rebuttals. Much appreciated. Rittz

I have not seen a residential building that used rafters and ceiling joists for a few years . Light frame trusses are used almost exclusively here in Western Canada , Much easier to install, and cost effective. No thrust to worry about either.

When I prepare a quote for specified engineering services (commercial or residential buildings) I give a good deal of thought to the degree risk exposure I feel I’m getting in to if I get the job. Are any of us ever completely confident that the project will be completed without any gaffs? BTW...

We are designing a foundation for a hopper bottom grain bin. It is supported on 20 individual legs on cast in place concrete piles (no slab). How would you treat the grain in terms of load factors in ultimate limit state design? Bin diam. 27’ Ht 38’ capacity 17,500 bus (1086 kips.). The piles...

Thanks for that sliderule. I appreciate your reply. I can print the text nut the diagrams won't come ... not even with screen shot. BTW I took all my training in engineering college using a slid rule. No such thing as computers then LOL J

Attached are a couple of pages from I piece I found in my files. Other pages are apparently misplaced. I wonder if anybody recognizes the source of the document and could tell me where to obtain a copy. Also I wonder if anybody could suggest another source of possibly r a more friendly piece for...

I am trying to upload a pdf of a drawing off the desktop as an attachment to a post. I have done this a few times before. What am I doing wrong now? -confused !

That's the first sign Mike.

Yes I am quite well of that. I'm rapidly becoming one myself
