The Advanced distribution settings option can be activated for the load transfer surfaces with the "Stripe" load transfer direction. Thus, the following two text boxes become accessible in the "Parameters" section:
- Stripe Width
- Sampling factor
The meaning of these parameters will be explained using a simple example.
What are stripes?
Stripes are used to divide the load transfer surface into surface strips along its x-axis, y-axis, or both axes. The load transfer to underlying objects is then calculated individually for each stripe.
Compared to the "Isotropic | FEM" method, this method has the advantage that the distribution loads can be calculated in a very short time. However, this is a simplified method, as the member or line loads always have a constant distribution within a stripe.
Stripe Width
You can use the "stripe width" parameter to control the width of a stripe. In the following image, different values for the stripe width were applied, which illustrate the influence.
What is a sampling factor?
The sampling factor controls how much to smooth the distribution of loads across the stripes. A low sampling factor means little to no smoothing. The distribution loads are then available as they were calculated using the stripe method. On the other hand, a high sampling factor signifies a strong smoothing of the distribution loads.
The following image shows the load distribution for a very small and a very large sampling factor.
