This article guides you through the input steps for dimensioning a linear expansion joint.

Procedure

Enter the parameters of the installation situation:

• Select a connection situation from the drop-down menu.

• Adjust the joint length according to your situation.
  Hint: If you require fire protection for the dowels, activate the "Fire protection" slider.
• In the next step, enter your planned and maximum joint width.
  Note: Instructions for calculating the maximum joint width can be found on our Website www.schoeck.com - Download - Technical Information - Schöck Stacon®
• If your two structural components are not at the same height or the dowel is not centred in the slab, you can define a height offset or an off-centre dowel position in the upcoming input fields.
• In the following fields, you then define the material of the product and the position of the sleeve (left or right component).
• At the bottom of this input mask you will find two tabs ("Left-hand structural component", "Right-hand structural component"). There you enter the following parameters for each panel side individually:
  • Slab thickness
  • Concrete cover top/bottom/front
  • Concrete strength class
  • Reinforcing steel

Note:

During the first parameter changes, you can track the changes directly in the display window. If you have already performed a calculation, the changes will only be visible once you have pressed "Calculate" again.

On-site reinforcement:

The default setting here is "Determine automatically". It makes sense to leave this setting for the time being. This means that you will first receive a reinforcement proposal. You can always change these values later.

Manual changes can be customised for each panel side ("Left-hand structural component", "Right-hand structural component").

Enter loads:

You can now enter your determined design load (VEd). You have the option to enter a constant or linear load, or make a free input.

Product installation:

In the product installation area, it's possible to change the number of dowels. It's advisable to leave the automatic installation activated for an initial result. This makes it more likely to get a result. You can always adjust this input later.

You can also change the product property to "Transversely movable dowels". It is possible for partial areas or the entire joint length.

Start calculation:

Once you have adjusted all the parameters to suit your situation, start the calculation by clicking on "Calculate".

Result of the dimensioning:

In the "Result" tab, you can see which Schöck Stacon®-types are possible/not possible.

You can check your results in the "System display", "Detailed view", "Item list" and "Verifications" tabs.

If an error or warning is displayed, you can use the command line at the top right to see which verifications could not be performed or which parameters should be checked again.

Create log:

You can generate a printable report by clicking on "Export log".

If your calculation contains an error, the printout report will be labelled accordingly.
