Question:
What is the meaning of the "Consider only increasing loads" feature in the wind load generator?

Answer:
If the internal pressure is activated in the wind load generator (see Image 01), the wind pressure on the internal surface of the building and the wind pressure on the external surface of the building are added (see Image 02).

If the internal pressure has a positive effect when determining the reaction size (we + wi), it is usually set to zero. This can be done by means of the "Consider only increasing loads" feature in the load generator (see Image 03).
