Panel on supports

[Anonymous]

Hi there,

I have a panel on some (internal) nodal supports and I am not sure if the reaction at the support is the reaction at the centre of the panel, on the top or at the bottom. The panel is 600mm deep and I need the reaction at the bottom of the panel.

This would be particularly important for deep panels as the eccentricity goes up.

Tia!

not clear what you need/want .

Picture , model(zip and attach) ?

@Rafacascudo see attached panel with internal support.

The panel in this case is 600mm and the lateral load is applied at the top of the column. The height of the column is 1m and the lateral load at the top of the column is 1kN. The reaction moment at the support is 1kNm i.e. it does not take the thickness of the panel into account and assumes that the bottom of the column is connected to the top of the panel. My question therefore is, should the reaction not be calculated at the centre of the panel and not the top? In which case, the moment should be 1.3m x 1kN = 1.3kNm?

the dimensions of the panel must be very large compared to its thickness.
From your image it seems that the dimensions of the panel are of the same order of magnitude as the thickness.

@Simau In any case the moment due to the eccentricity created by the thickness of the panel must be calculated.

I don't think so.

For a panel, the forces are applied at mid-thickness, not at the upper or lower face. There is no notion of eccentricity.
