constant measurments??

[ReMark]

The assignment is for an AutoCAD class and not one of your civil engineering classes?

[areejo0o]

thats right.. u can see it in page 2..

[ReMark]

Finally some detail! Praise Allah.

 

Guess what? We are talking about steel reinforcement bars for one thing. And we are not in the United States because the bar designations are totally different.

[areejo0o]

whats that one thing ? make u know that is steel not wood..?

if have some patient from the beginning u will never be in this angry mood

[ReMark]

Looks like you have a lot of work to do. Better get busy.

 

Take a pen, pencil or highlighter and circle or highlight every single dimension you can find.

 

Draw everything in model space at full scale. If the dimension is 100mm then draw it that size.

 

Do you have a handbook that lists reinforcement bar sizes?

 

How much experience do you have using AutoCAD?

[areejo0o]

I start using it from one month only..

and I don't have a handbook..

You have a real knack for being annoying. And I should help you because...?

 

I know it is steel and not wood because even without the labels or notes the details look exactly the same as they would here in the United States. Anyways, steel rebar would not be used to reinforce a wood beam.

[areejo0o]

thanx for ur answer..

[ReMark]

Example: 2Y12

 

My interpretation is as follows...

 

2 - the number of bars.

 

Y - the type of bar

 

12 - the diameter of the bar

 

C/C would mean center-to-center.

[ReMark]

Draw everything FULL size in model space.

 

Make sure to use Ortho mode to keep lines perfectly straight where required.

 

Use your Osnaps to ensure accuracy.

 

Set up layers for concrete, reinforcing bar (rebar), dimensions, text, etc. Do NOT draw everything on layer 0!

 

Load all necessary linetypes like centerline, etc.

[areejo0o]

y- the type of bar?

I don't understand that part.. what type y mean?

 

what w , D, B mean?

that also types?

 

really thaaaaaaaaaaaaaanks for answering

[ReMark]

W = Width

 

D = Depth

 

B = ? I don't know but looking at where it is used I'd have to say it too is referring to width as well. Not sure why that particular designation is used.

 

Y - type of bar. Again, it's a guess. Maybe it is a type of non-coated steel rebar as opposed to an epoxy coated rebar. Maybe it is a grade of steel common in your part of the world? I just don't know.

 

We do have at least one other forum member viviancarvalho who works in Bahrain in the HVAC field (you do know what that means right)? Not sure if she would know.

[areejo0o]

thanx alot .. sorry for being annoying ..

but I really have good information from u..

maybe come back again if I have any questions..

bye

[ReMark]

You're welcomed.

 

I need to go now myself. I have a headache. Wonder how i got it?

[MikeScott]

Y12 is a bar size

I'm glad I'm not in that class.. that looks like a nightmare.

[ReMark]

A "Y" bar is a deformed bar. Makes sense looking at the images.

 

Can you believe the OP did not know whether the assignment was talking about steel or wood beams? Unbelievable. Future civil engineer. GHU

[MikeScott]

A deformed bar? that's Rebar, right?

[ReMark]

Yes, we're still talking rebar. A deformed or bent bar would be something other than a straight one. Hooks are an example of a bent bar.

[eldon]

This sounds like a reinforced concrete structure assignment.

 

Reinforcement bars are commonly plain Round bar ®, or High-Yield-stress bars (Y) which are stronger. The deformed bar can be a square-twisted bars or twisted ribbed bar or there are several other ways of cold working to increase the strength, and the designation 'deformed' indicates the appearance of the bar rather than its shape. You can have either straight or bent deformed bars.

 

Sorry that I didn't chime in sooner, but the thread title did not sound terribly technical

[CarlB]

And to elaborate on "deformed", it has to do with the surface texture which is deformed to increase its bond with concrete (as opposed to a smooth surface). So yeah, the term "rebar" usually means the standard deformed reinforcing bar

 

From http://www.answers.com/topic/deformed-bar

A steel reinforcing bar which is manufactured with surface deformations to provide a locking anchorage with surrounding concrete.
