International Hatching pattern for RC Concrete

[nazihmahmoud32]

Hello,

I need to know the International Hatching pattern for RC Concrete Sections.

isn't it a single spaced diagonal lines on an angle of 45 ? 

the consultant says it is not the international pattern.

so i need a reference  for any answer.

There are many hatch standards. I can think of ANSI - AFNOR - ISO or SIA. And there certanly is many more around the globe
Lot's of offices use a hatch pallette mixed out of those standards. example: my office (switzerland) uses AR-CONC for lighted concret and ANSI37 for reinforced concrete, certainly because they are by default there in Autocad

But to give you a clear respons, ISO hatch is what you're looking for

ISO stands for International Standardization Organisation → ISO - International Organization for Standardization

Almost everyone uses the triangle and dots pattern for concrete, in autocad that's AR_CONC.

If you have to differentiate between normal and reinforced concrete (personally we don't and I rarely see it) I'd overlay the ANSI32, the single spaced diagonal lines at 45°.

ISO 128 (128-50) specifies the standards for technical drawings.

If you have a legend saying which hatch means what I don't see an issue.

While checking some infos, looks like ISO 128-50:2001 (ISO 128-50:2001 - Dessins techniques — Principes généraux de représentation — Partie 50: Conventions...)  is out of date.

Indeed, every few years, ISO actualise theirs normes.

The most recent is (and actually what ISO 128-50 evolved into)→ ISO 128-3:2022 - Technical product documentation (TPD) — General principles of representation — Part...

That said, I think most of people steal refers to the 2001 version. People don't like to change their habits...

Fifty shades of grey.

for the american code 

i need only a screenshot as this file is paid

[nazihmahmoud32]

yeah i need to differentiate between plain and RC

I'm not alowed and can't provied ISO's hatch pattern. 
You'll certainly be able to find  those pdf. somehow and and somewhere trought internet in a free cost way

My two replies answer post's issues (what are international hatch norms and their references) in an extensive way.


For the two hatches I referenced to (AR_CONC and ANSI37),  you can find those by default installed in Autocad

Here is what they look like ↓
