WOOD MOMENT FRAMES

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I HAVE A CLIENT WHO WANTS TO USE A WOOD BEAM IN CONJUNCTION WITH STEEL COLUMNS
TO CREATE A MOMENT FRAME. THIS IS RESIDENTIAL CONSTRUCTION IS SEISMIC ZONE 2.
I AM VERY HESITANT DUE TO:
1. THE ENORMOUS AMOUNT OF BOLTS REQUIRED AT EACH END
2. THE IMPRACTICALITY OF EXPECTING RESIDENTIAL CARPENTERS TO GET THE BOLT
HOLES EXACTLY RIGHT (SINCE THE BOLT HOLE WILL NEED TO BE SNUG WITH THE BOLTS
IN ORDER TO MAINTAIN A RIGID CONNECTION)
3. THE POSSIBLE FUTURE ELONGATION OF THE BOLT HOLES DUE TO CONTINUES MOTION
OVER THE YEARS. 

IF ANYONE HAS ANY SUGGESTIONS, THEY WOULD BE GREATLY APPRECIATED.
