Wall loading distribution

[skilak]

Hi,

I have created walls for UDL loading. I have created bracing as truss members as I do not want them picking up any loads but it seems a bit different on the attached model: I have done a basic check on the column no 6 as shown on the attached picture - the column should have BM of around 6.6kNm but the soft shows 5.6 kNm (I guess it is due to fact the bracing picks up the load). The odd fact is that the bracings do not show any bending moments. Please could you advice on this matter? Thanks in advance.

As far as I can see you defined bracing as a truss bar which is capable of taking both tension and compression (with no bending). You should define them as tension only bar (you can do so in the same dialog where you defined the truss bar attribute) so that no compression is transferred to this bar (it works only for tension force).

And how is it linked to the load distribution?? I think you missunderstood my problem;). I want the bracings to be not taken into load distribution from  walls to columns. On the first picture you can see that the distribution patern shows that the bracings are considered in the distribution. I want the bracings to be not considered in the load distribution. the bracings are struts, thus have to stay tension and compression.

Possibly 

I assumed that  you mean the vertical loads but if that is for horizontal loads applied to walls which are claddings (or the triangular and trapezoidal load distribution method is used) then use the option shown below:

Thanks 😉

Now it works as I wanted, Thanks a lot (and I know that Robot is FEM, this is why I use it;)

Cheers,
