What is the meaning of the “Consider Only Increasing Loads” function in the wind load generator?


If the internal pressure is considered in the wind load generator (see Figure 1), the wind pressure on the inner area of the building and the wind pressure on the outer area of the building is added (see Figure 2).

If the internal pressure has a positive effect when determining the reaction size (we + wi), it is usually set to zero. It can be done by means of the “Consider Only Increasing Loads” function in the load generator (see Figure 3).
