The "Assign data for the capacity check" option is located in the "Beams" menu of the "Beam input" tab and appears in projects where seismic action has been activated.

This option allows the contribution of the effective width of the slab to be considered in the analysis of the beam's yield moments for capacity checks.

To do this, tick the "Assign slab contribution" box in the pop-up window and enter the following values:

• the "Effective width (1)" for positive moments,
• the "Effective width (2)" for negative moments,
• the "Effective depth (3)",
• the "Mechanical ratio of the bottom reinforcement",
• and the "Mechanical ratio of the top reinforcement".

After clicking on "Assign", select the side wall at the end of the beam in contact with a pillar from which the data will be copied. The meeting points are represented on the plan by triangular symbols. These symbols are filled in with colour if the previous box has been ticked, lighting up in magenta if they have the same data assigned as in the dialogue box.

The "Copy from" option allows you to take the data from the selected meeting point on the floor plan, while the "Finish" option allows you to exit the dialogue box.
