I've actually done that, firstly with a 3.0 m long × 3.0 m high panel, and again with a 1.0 m long × 3.0 m high panel, to try and understand how the program works.
But I am not talking about any particular wall being "pushed over", I am talking about the blocks "blowing out" i.e. failure of a wall panel due to out-of-plane forces. I do hope that makes sense to you.
I can't see anything in either the input data, or the output data, that indicates that the program actually calculates out-of-plane bending, either capacity or demand.
What we are talking about here is really as if the blocks were "infill". If the surrounding concrete frame responds elastically and deflects very little due to in-plane forces, then in theory the confining reinforced concrete structural elements have to physically elongate for the blocks to fall out of the wall at 90°. So the failure mechanism could either be this happening, or the individual bonds between the blocks failing in out-of-plane shear.
If you imagine a stack of bricks which you can just push over. If you put a beam along the top which is properly restrained, you cannot push over the wall so easily. But the individual blocks could fall out of the wall when pushed. If you then apply vertical force, the wall becomes more resistant to out-of-plane forces due to frictional forces being generated between the blocks.
I'm assuming that when you do calculations for a structure in a high seismic area, the local authority would expect to see calculations (or otherwise) demonstrating that the walls will not fail in this manner. Since I am using Weinerberger Porotherm th+ 25 blocks (from France), this may be something that can only be determined by shake-table testing perhaps?
Any advice that you have on how you deal with this would be most welcome, assuming that the program does not take this failure mechanism into account.
