I appreciate the responses. I was able to go see the home in person yesterday and wanted to post my findings here. The basement is unfinished so I was able to see a lot of good stuff.
The existing floor joists are 12" TJI and run perpendicular to the opening in question. Anchor bolts are spaced...
Hi all. I've got a potential project where the owner wants to replace an existing 24"x24" window in a basement bedroom with a 48"x48" window. It is an 8" thick concrete wall and the load coming down from roof and floor above will be approximately 1 kip/ft.
Obviously they would need to cut the...
Yeah sorry, I shouldn't have said that. It's just that I'm having flashbacks to when I first started out and my boss always acted super annoyed when I asked for help. He'd tell me to come up with something that I thought would work, so I'd sit in my cubicle for 3 hours sweating it out, doing...
Sarbear, don't pay any mind to this douchy comment from chris3eb. My guess is your boss wants to see if you can find and use any and all resources at your disposal to come up with a solution to a problem instead of just having him tell you what to do. I don't see what the problem is with...
The column is 9 ft. tall, DF-L #2. I'm getting an axial compression capacity of around 17 kips. Plan is to tie the lateral wind and seismic into the back wall of the house through the roof diaphragm so no lateral loads or uplift on the column
Thanks, dik. On this particular project both of these beams will be load bearing. The covered patio has a large hipped roof so both beams will be carrying some of the weight of the patio roof.
Hi all,
I worked on a plan with two 5 1/8" x 15" glulam beams coming together over a 6x6 post at a covered patio. Each beam has a load of about 5 kips. I called out one of these bad boys on the plans to attach the beams to the post (picture on the left). Instead, the builder would like to miter...
You mean cantilever steel columns at the exterior like my original design?
So if I try to drag the load into beams that hang into steel posts in the wall, I also need to make sure that the end trusses are attached to the beams properly. Load path is patio roof diaphragm > beams > steel posts in...
Yes, you are right and that would decrease the forces in the left-to-right direction. However, when the seismic load is applied perpendicular to where I currently show it, the forces into each wall column will be the same as I am showing them currently. A big consideration here is the R value...
So many questions...
If I try the diaphragm route suggested by MIStructE_IRE then I guess my R value is 2.5 since I'd be tying it back into cantilever steel columns in the garage wall? I calculate the dead weight of this roof to be 6750 lb. (18' x 25' x 15 psf = 6750 lb.). With R=2.5 my seismic...
I already did the engineering for this residence a few months ago. The contractor has come back complaining about my design as it's not what he's used to seeing in this area. In his defense, he is correct about what I spec'd out not being the norm. What I did was engineer these three columns at...
Here is a side and front view of the connection at the corner.
The out of plane loads I'm thinking about are wind loads perpendicular to the faces of the walls. On a normal window opening the wind that hits a big window or door opening would transfer into king studs at the ends of the header...
The way ASCE words the definition of mean roof height, if you have a flat roof then the mean roof height is the height of the eave above the grade. So in your case it seems to me that your choices are to use 20 feet, 50 feet, or something in between. I wouldn't go with 20 feet since that would...
Good afternoon, I have a wood-framed residence here with a corner window. I wanted to run my idea past you all here to see what you think. The snow load in this area is large (65 psf roof snow), thus the outriggers shown. Also, the roof framing here are parallel chord trusses where the slope for...
Thank you jay and Tmoose. I had a brain fart with the clips. I was thinking that the shear blocking would interfere with the H-clips but of course the H-clips would be installed before the blocking. Duh.
Tmoose I've looked at quite a few details like that from various suppliers but none of them...
Hi everyone,
I'm currently drawing some generic details for future use. One of the details I need is where an I-joist is used as a rafter and connects to the wall framing. Where I am contractors almost exclusively use I-joists for roof rafters instead of dimensional lumber. I have seen details...
Thanks for the responses.
phamENG, yes on the right end of the beam I'm not sure whether there is a plate on the foundation or not. Neglected to draw that in. I'm assuming there is a plate because that currently is a framed wall between stairs that go up and down. Won't know until the...
Hello gals and gents, I'm working on a basement remodel which I haven't done much of in the past. We're replacing a bearing wall with a new beam. Pretty simple. However, as I was working through this I started to consider the connections of the new 6x6 posts to the foundation walls. One of these...
Exactly, thus my original question: why do the CSRI tables appear to suggest that the "O" bars for walls taller than 6' don't have a hook into the toe? They have the "Hk" designation for the "O" bars on 6' and shorter walls, but not for anything taller than 6'.
That's what I would normally...
