Thank you Eric and Archie. I explained to the GC the bond beam is necessary (although, not technically required by code). Anchor bolts are spaced at approximately 48" o.c.; Cells are grouted at 32" o.c. - so we must use a bond beam.
Archie, it's crazy - but the GC's bid was based off the...
Thank you for the responses. I totally agree! I was just checking to see if anyone knows of a code section (ACI530, TMS 402, or IBC) that notes a bond beam is required at the top of masonry walls.. i can not find one. I've come to the conclusion the code does not require a bond beam at the...
You're correct, most courses are grouted solid, except for the top coursing b/c it will be above grade.. which is part of my issue. I would like the bond beam also to tie the wall together to resist pull-out from the holddown anchorage. The GC only wants to hear what is mandated by the code...
I have a multi-story wood structure (3 stories) on a conventional spread footing. The GC prefers to use a masonry foundation wall around the exterior. Our typical detail indicates a bond beam at the top of the masonry foundation wall. Our contractor is questioning the use of the bond beam. I...
No need to brace the columns if designed correctly. The size of the columns may be so ridiculous that you need to do something, but I'd start by sizing the columns, unbraced, and going from there.
What's the height of the columns and what's the load to the columns?
Good point ajh1. "In real life", I would have to think that at least some of the snow does blow away, especially if there is a 100ft difference in roof elevations.
According to ASCE 7-10, the answer is never. The calculation to determine leeward drift height only takes into account your upper roof length and ground snow load. See section 7.7 in ASCE 7-10 "Drift on Lower Roofs".
When going through the entire calculation, the difference in roof...
Thanks wannabe! I figured to use the most conservative value. My thirst of knowledge was curious of why there were separate values. I found the actual reason for separate values on the internet over the weekend, which was way more in depth than i could have ever imagined.
