Simple one way Load Distribution - strange output

[Anonymous]

Hi,

I have set up a large one way spanning floor over several bays with steel members. 

The nodes are all perfetly lined up to the 6th decimal place in the relevant X Y and Z directions.

See attached image, I am not sure why robot has extended out the yellow load distribution. I understand that at node 374, the  connecting beam acts as a point load on the beam between nodes 14 and 16. But this should not affect the load distribution on the beams between nodes 16 and 18 and 14 and 12.

What is happening?

You are right. 

The nodes marked below in white are the cause of it.

Example for panel 2054

To avoid it you have to ignore bars 4999 5038 5044 5045 in cladding loads distribution

Additionally I recommend to correct accuracies in your model to avid other problems with cladding loads distribution

(grids and bar nodes also)

Sample file for your consideration

Great thank you!! What is this Excel sheet you are using? Can I get a copy of it to correct my model? Thanks!

I have just had a look at what you sent over, but I think the wrong bars must have been ignored. This is because the ignored bars should have load distributed to them, have you maybe ignored the wrong bars?

This is a workaround.
If it is not suitable for you \ your model it means you have to apply loads manually for now.
