Surface Loads
The next thing we need to do is to put surface loads on the plates. We will apply a
uniform .1ksf (100psf) load to all plates, as part of Basic Load Case 3. The
surface load is applied uniformly over the surface of the plate.
First click on the Joint Labels button, which will remove the labels from the
model view. Then, on the Drawing toolbar click the Surface Loads button.
Change the direction to Y (Make sure you use the upper case “Y”). Click in the
Magnitude field and enter “-0.1”. Click the down arrow in the Basic Load
Case field and choose “3: Live Load”. Finally choose Apply Load to All
Selected Plates.
