Penn Foster Drafting with AutoCad Structural help with the rebar.

[ReMark]

I've noticed a couple of things.

[ConfusedStudent]

Good, bad or indifferent? I'm really trying to do my best even though I'm not sure the diploma will be worth anything when I'm done. I'm hoping the knowledge will be sufficient.

[ReMark]

For some reason the "J" bolt in the column baseplate and the keyway in the footing both caught my eye.

[ConfusedStudent]

Probably because I saw something that I like the look of for the bolt and did my best to replicate it. The keyway is spelled out pretty clearly in the directions.

[ReMark]

Most keyways I am familiar with are wider than they are tall. The "J" bolt does not appear to have the same width throughout. Maybe it's an optical allusion.

[ConfusedStudent]

Hmmm The instructions just say "A 2X4 keyway is centered at the top of each footing." I know a keyway is cut down into the footing but without a reference I just guessed. Thank you. I will check my widths but I hope it's an illusion. I used the offset command to do them.

[ConfusedStudent]

Keyways are modified. Thank you again. and I checked the J bolts they are the same throughout so it is an illusion thankfully.

I'm having trouble with plate 6. Detail D is supposed to be connection B4. According to the way I've drawn this, that would be a connection of 2 I beams. Detail D1 they are asking to show the angle and connections. But those should not be connected at B4 - should they? I'm really confused.

[ReMark]

I'm pretty sure that an image of that detail is posted in one of the P-F structural threads.

The connection is supposed to show two C9x20 angles connected to a single W12x45 beam using clips comprised of 4x4x1/2 angles and secured with 5/8" dia. x2 1/2" lg. bolts. The W12x45 beam, in turn, connects to a W12x152 column. In other words, the instructions in this case are correct.

 

Take a look at this thread specifically page 13 post #125.

Thank you I will look there.

[Hondatek]

Confusedstudent how you coming on the last 2 plates on structural? Lot of details i see.

[ConfusedStudent]

I finished the project. handed it in for grading and started the next. I hope to not have as much difficulty with the Civil project.

[ConfusedStudent]

Did you finish and hand yours in?

[Hondatek]

Im stressing over the last two plate. On all the detail and dimensions. Ill post what i have on both plates

[Hondatek]

What can you help me with. Getting frustrated here.

[Hondatek]

I tried the civil and put it back down till i finish this one.

[ConfusedStudent]

Why do you have a c channel in the middle of plate 6? It's hard to tell but I think you're doing ok. You only have part of plate 7 done.

[Hondatek]

THE c9x20 DON'T LEAVE THAT THERE?

[ConfusedStudent]

Those look fine. I was talking about the one in the center of the page. It looks like it's in the middle of all 4 drawings.
