How can I avoid singularities in the case of point loads?


In order to be able to apply loads properly in a support, there are various possibilities.

Since the support is also not point-shaped in reality, it is reasonable to use a rigid surface with the size of the support for the load introduction. Rigid members or couplings are also suitable here.

Figure 01 shows an example, where a member in the middle of a surface should transfer the load. In this case, the transition was modeled by using a frame made of rigid members. As an alternative, you can use a rigid surface. However, it should be noted that it is necessary to use a cross of rigid members for the transfer of moments.
