Wood Beam Moment connection
Wood Beam Moment connection
(OP)
The owner wants to add a cantilever balcony to an existing wall, I consider using nails or bolts subject to eccentric shear method as mostly used in steel, but the bolt size ends up too big for the wood member, Anyone has any sujestions? (L Cantilier=4' and Pu=1300 lbs)






RE: Wood Beam Moment connection
If this is a wood framed building, can you extend the framing back into the building and lap the existing joists?
How about adding a diagonal brace under the cantilever?
RE: Wood Beam Moment connection
No I can not do diagonal brace under the cantilever, but yes, I can extend it into the existing 2x10 joist but how would you find out how many nails or bolt you need to do the splice, I found out that the fisrt bolt will be 1 1/2 inch, I am not sure, if I am using the right method ( the same way as we do in steel structure, eccentric shear), any suggestion for splice and analysis?

Do you really need such a large bolt at the outside wall? Isn't the joists sitting on a bearing wall at the outside wall? Wouldn't the balcony joists also bear at the same location?
The forces at the connections can be figured like a simple beam supported at two locations with a cantilevered end. Extend the lap farther, if you need to reduce the connection forces.

I will be appreciated if you give me any ref. for this case or showing how the side plate and rivets are used in moment connection?

APA has some info. under "APA Performance Rated I-Joists" on this subject,and the follwing web site http://www.euken.net/group/seaint/mailarchive/2003b/msg00659.html

Yes... just recently a 30' span gambrel style roof where the owner wanted to use the space... without cross ties...
