SCIA Engineer: How do the different types of load panels work?

Panels (sometimes also called loading panels) are entities that are not considered in the FEM analysis. The stiffness is thus not taken into account in the calculation, but they are capable of redistributing the applied surface load to other load bearing entities supporting the panel. The panel can transform the applied load to nodes (corners), edges (opening edges), or beams situated in the plane of the panel (beams supporting the panel).

The applied load can be distributed in one or two directions according to the user setting.

SCIA Engineer Load Panels

Load to panel nodes

A panel of this type transfers the applied load to all or selected nodes (corners) of the panel. The load is generated only in supported nodes. The total load is distributed to individual nodes according to the length of edges connected to each node. The user can set the weight for individual nodes or exclude some of them from the load transfer.
The panel supports can be displayed. All load types can be used on the panel. The panel is available in all project types - Frame, Grid, General, etc.

SCIA Engineer Load Panels

Load to panel edges

A panel of this type transfers the applied load to all or selected edges of the panel. The load is generated only along supported edges. The total load is distributed to edges proportionally to the length of the edges. The user can adjust the weight for individual edges or exclude some of them.
Supports can be formed by beams or edges of 2D members. It is not possible to define a direct support on the load panel. If an edge is only partly supported, then a point load is generated at the end of the support.
The panel supports can be displayed. All load types can be used on the panel. The panel is available in all project types - Frame, Grid, General, etc.

Load to opening edges

This type is analogous to the previous one. The difference is that for this type an opening is defined where the load is transferred to the edges of the opening. The properties of such load panel are limited.

Load to panel beams

A panel of this type transfers the applied load to all or selected beams that are located (with a defined tolerance) in the plane of the panel. If the panel has some edges supported, these supported edges are treated like beams, i.e. the load is transferred to them as well. It is not possible to define a direct support on the load panel.

The user can choose a method that transfers the load to the beams. There are two methods available:

  • Standard
    The total load is distributed to beams proportionally to the length of individual beams and supported edges. The user can set the weight factor for individual beams or exclude some of them.
  • Accurate (FEM)
    The finite element method is used to recalculate the applied load to individual beams.

All load types can be used on the panel. The panel is available in all project types - Frame, Grid, General, etc.
