I wonder if anyone has a clear reference for the tie bar requirements in a trench footing. For this example lets say we have a 2'-0" deep footing thats 1'-8" wide. Cast against dirt so 3" cover, and (3) #4 bars top and bottom with ties at 16" o.c....Oh No! the clear spacing of our longitudenal...
Hey All,
Could someone clarify for me the purpose of the additional reinforcing (or higher reinforcing ratio of 0.0025) of composite beams with web openings. I've flipped through AISC design guide #2, and see the reference, but not the purpose. What do people do when they are using composite...
Hey All,
I had an interesting change-order the other day due to stair framing in a moment frame building. Apparently the drift was more than expected (although still a drift ratio under 0.0015) This had me thinking on what information is most critical for those who do stair design. In this case...
Hey All,
I'm looking for some guidance on table 12.12-1. More than anything I guess I'm looking for a poll on the matter. Most of my engineering has been outside of seismic country, so my code understanding is pretty academic. What would the limit of a single story RC-II SMF building be for...
Hi, I was wondering about this the other day and am curious to know if any states/counties amend the code to require seismic mass consideration for snow drift. I know our ASCE 7-10 20% of uniform >30 accounts for the lower probability of having design snow and a seismic event, but it seems to me...
