RE: Glulam Roof Girders in a Tilt-Up

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Bill, I'm not so.  I think I will go along with your first post.  What is to prevent the horizontal component of the brace reaction from being resisted by the brace to the unloaded beam and then into the beam itself?  Certainly the beam is stiffer than the column.

Ahhhh. Now I get it. Excellent drawing :o).

 

Looks like the braces are good for the beam and bad for the columns.

Maybe I painted a poor picture.  It looks something like this (monospaced font):

 

Load here            no load here

Splice or no splice at the column, it will induce bending when the reaction to the left kicker is bigger than the right.

Jake-

 

If I’m seeing the picture correctly, I disagree that there will be moments in the columns due to unbalanced live loading.

 

Just my two cents.
