Note: in case of multiple layers of reinforcement, you enter the mean cover.

In Diamonds you define the gross coverage.

• Select the element for which you want to change the cover
• Click on and on the button “Reinforcement”.
  

In ConCrete you define the net coverage.  ConCrete will automatically add 10mm to the coverage.

So if you model a beam with a coverage of 35mm in Diamonds, and you want to model the same beam in ConCrete, you should set the coverage to 25mm. Because ConCrete will automatically add 10mm to the coverage.

But you also have to take the increase in longitudinal reinforcement into account. Low θ-values ​​require more longitudinal reinforcement and cause anchoring problems at the beam ends. Often resulting in additional bars to meet the anchoring conditions.

Thus a low θ-value doesn’t result in an economical optimal concrete strut.

The results of practical and theoretical reaseach on this matter have been published in a paper from R. Manuoi and J. Rondal, “Optimal shear design of beams with CEB-FIB Model Code‘. From this paper the choice θ = 31° appears to be the most optimal solution.

Solution

• Reset the ConCrete preferences.

Exception error: DOCHANGINGINVOER.1
Cannot focus a disabled or invisible window
ConCrete Error Log adjusted

Solution

• Define a local printer as default printer

Beams poured in two stages are only possible with ConCrete. Not in Diamonds.

• Set a local printer as default printer.

Solution 2

• Reset the ConCrete preferences.

Solution 3

• Uninstall ConCrete using the Control Panel
• Go to the folder: C:\Users\*YourUserName*\AppData\Local\VirtualStore\Program Files (x86)\BuildSoft\ConCrete
  Delete left over content.
• Install ConCrete again.
• Start ConCrete.
  If a pop-up shows up, asking you to install Aladdin, accept it.
  He should ask you the language and continue the start-up.

Solution

• Open ConCrete and close it again.
• You must have your old CONCRETE_7.PRF file (before the preference reset).
  • If you did not save it, look for it in the Recycle Bin.
  • Copy this file to your desktop
  • Rename it to CONCRETE_7_OLD.PRF
  • Open CONCRETE_7_OLD.PRF
  • Look for aantwelfsels
  • Copy the HCS data between aantwelfsels and toonmaxAs
• Go to C:\Users\*Your_UserName*\AppData\Local\VirtualStore\Program Files (x86)\BuildSoft\ConCrete. Note that the folder ‘AppData’ is a hidden folder.
• Open the new CONCRETE_7.PRF
  • Look for aantwelfsels=0
  • Pase the HCS data from CONCRETE_7_OLD.PRF in the new file CONCRETE_7.PRF
  • Make sure you online have 1 line aantwelfsels and that the number is correct
  • The end result will look something like this

Problem with the link between ConCrete and ConCrete Plus DLL.

Solution 1

• Reset the ConCrete preferences.

Solution 2

• Set a local printer as default printer.

A continuous beam

• 2 spans
  • 3m
  • 4m
• rectangular cross-section b=190mm & h=500mm
• 2 loads:
  • selfweight : 2.38 kN/m
  • dead load : 20 kN/m

Let us now sum up ULS minimal reactions (we expect the load factor here to be 1) and compare this with the total load

• total load : (20 kN/m + 2.38 kN/m) * 7m = 156,6 kN
• reactions ULS : 18.46 kN + 99.52 kN + 34.72 kN = 152,7 kN ≠ 156.6 kN
  

Solution

The displayed ULS minimal reactions do not necessarely correspond with all load factor equal to 1.  ConCrete calculates the enveloppe of the loads, calculated with load factors 1.35 and 1, and distillates the minimal reactions.

You can only compare the total loading with the reaction in SLS RC (Serviceability Limit State Rare Combination), here the load factors are always 1. You can display the SLS RC reactions by clicking the   icon and opt to see the combination SLS RC in the dialog window that pops up.

Check SLS RC

• 21.44 kN + 99.52 kN + 35.66 kN = 156,6 kN = total load

Solution

1. Go to the Desktop
2. Right click with the mouse on an empty space, a floating menu appears
3. Choose Display Settings (NL: Beeldscherminstellingen)
4. Verify that the Scale and layout is at 100%
