Setting Current Load Case

In addition to the self-weight of the model which is accounted for automatically (see Chapter Load Cases), the weight of the floor is to be considered for the concrete slabs. Click the button on the toolbar to define the loads on those surfaces.

Button "New Surface Load"

In the 'Parameters' area of the 'New Surface Load' dialog box, enter the value of -0.015 ksf (see Chapter System and Loads).

'New Surface Load' dialog box

Then click the button in the 'Assigned to Surfaces' area (2) to select the two slabs (nos. 4 and 5).

Selecting Slabs

Click OK and return to the 'New Surface Load' dialog box.

Instead of clicking OK (which would close the dialog box), continue defining surface loads by clicking Apply & Next.

The loads are applied to the two slabs.
