CONCRETE AND REINFORCEMENT BAR

[petite24021989]

Hello everyone!

I tried to design structure according to Russian standard SNiP 2.03.01-84, and I had some problem with create new concrete material and strength of reinforcement bar: (Model is attached below)

1. First problem: in “material definition” screen, I created new concrete materials. However, when I tried to delete one of them, the software automatically created a new material name “concrete” and erased some default materials. For example, I deleted B10(M50)_TCVN, the default material B3_5 was gone.

2. Second problem: I created a material called: TCVN_B22.5(M300) with standard strength of 167 daN/cm2. Howoever, in calculation module of steel columns “provided reinforcement”, the software did not present the correct strength value, as below:

3. Third problem: I created a steel material called “CB300-V”, with standard strength of 3000 daN/cm2 -> the calculated strength was 2600 daN/cm2. However, the software did not calculate the correct calculated strength, as belows:

Thank you for caring!

Hi @petite24021989,

As far as I remember, materials for SNiP 2.03.01-84 are hardcoded i.e. it is not possible to create user materials and use them.

Thank @Romanich!

What should I do to restore default concrete grades, for example the missing concrete grade B3_5? I tried to reinstall the program, but it didn't work.

Hi @petite24021989,

Try to close Robot, rename folder c:\Users\USER NAME\AppData\Roaming\Autodesk\Robot Structural Analysis Professional 2024\CfgUsr\ and re-run Robot
