To kelowna,
I like to separate the deck from house so it'll not need permit. I try to find the frostline because I'm afraid the foundation above frostline and may have big displacement.
Thank you.
I live in Mississauga. I feel the frostline may be less than 1.2m.
It's a small deck (3mX3m) in backyard, I wish the foundation is simple as possible.
To calculor1?
Yes. But I can't find L2 in fig 2-15 case 1 match this note.
Same as L2 in case4.
To dik ,
We can use omiga2=1 conservative in design, but it's no the reason in this case.
Af is flange area in this code, does it include compression and tension flange?
I can't find more commentary for it and the similar formula?Af is compression flange area in AISC 89. So I want to make sure I didn't misunderstand.
Thank you.
I don't think that using eccentricity=45+flang width/2 is a good practice - if the girder is big, let say 3m and the neam is small (W21 or W24).
How to calculation the eccentricity of beam to column connetion?
To enginering?
I see.
Just want to know a common situation. For example, one would like to control KL/r around 90-150 for column.
p-delta effect was some thing we can control by change the
rigidity of structure, as I understand. Similar as KL/r, I think it may have a allowance value.
What percentage the p-delta contribute to stress ratio
for column of steel structure you found?
I got 1% for braced frame and 5% for moment resistent frame.
It depends on the the stiffeness of girder and the connetion plate.
Girder support was torsion resistance. If you consider girder length=0, it's the situation of Korea's calculation.
To StructuralEIT,
We consider pure bending, the idealistic situation. If not connection, how can the flanges and web work together? Bending for 3 plates separately or "W" shape is total different
You're right.
Some time I'm not confident to the result. I had a gider with 26mm web. Full strength weld thickness =26/.7/2=19mm(2 sides), shear capacity design only need 10mm thickness (2 sides). The weld strength is only 54% strength of web.
If the flange to web welds is not develop the full capacity of web. How to check the weld strength?
Let say, web=30mm, bending f=0.6Fy, shear ft=0.2Fy, how to calculated the weld thickness?
