Load transfer method on panel
Different methods are available for the loads transfer via load panels :
Which one to choose?
By default, the method is « Tributary area » : loads are distributed according to the break lines.
But this method is available only with uniform surface loads on the whole panel.
In case of partial surface loads on a panel, or triangular loads, or trapezoidal loads, …, a warning will be displayed because we need to use another method.
This method is close to the tributary areas method, because the distribution is divided by 2 on each side.
- "Accurate (FEM), hinged link with beams"
In this last case, the load is distributed according to factors.
In the above example, the load would be distributed by 1/3, 1/3, 1/3 on each bar, because factor 1 is defined on each bar (even if the load is a linear or a point load in a corner of the panel).
The distribution doesn’t take into account the loads locations, but rather the defined factors.
This method is less used than the others.
Let’s have a look at the simple example below :
Let’s apply a surface horizontal load on each panel.
Results are in line with the previous description of this option :
