two-way cladding load distribution between beam and wall

[eear_gabriel]

Does anyone know why my cladding distribute loads differently when I have 4 beams or I have 2 beams and 2 walls.

Hi @eear_gabriel 

In second case forces generated from cladding are converted to linear load on panel edge. Robot does not support trapezoidal loads on panel edges. If you need trapezoidal load on that edge fictitious (low stiffness and weightless) bar can be defined along wall edge

Probably because the generated load is a bar "trapezoidal load" for both halves of the bars and for the wall it is a "linear load on edge" . Maybe they (autodesk) could have done "linear load 2p" for the wall load to have a similar load. But then, you have to ask them.

Hi guys, thanks for the prompt answer.

My walls are made of 190mm thick concrete masonry block core filled with reinforced concrete (16mm bars at 400 centers if I'm not wrong). The cladding is representing a 6000x6000x 250mm thick slab (supported on 4 sides by the 2 walls and 2 upstand beams).

What's the best way to model it in order to get the closest to real life? I believe the walls would attract more load than the upstand beams? Would it be safer just design the beams a triangular distribution of loads?

Thanks in advance

Hi @eear_gabriel 

If you want to get load distribution depending on object stiffness define slab as shell object.

To simulate beam stiffness regarding beam neutral axis real position (below slab) you can define offsets or modify beam stiffness according to recommendation from this thread load transfer to beam
