Robot adding fixed supports

Anonymous — Tue, 28 Nov 2017 10:36:35 GMT

Hi,

I am wondering why Robot keeps adding fixed supports to nodes 2 and 174 every time I run it. I presume it has to do with instabilities, but I am unable to resolve this.

I have not found much information on this within the Forums.

Thanks.

Because you assigned a linear fixed support to those vertical edges. There´s no "physical linear supports. Nodal fixed supports are assigned to all nodes that lie on thieses edges. So you have use the linear tab together with the Delete choice and select those edges to get the fixed nodal supports deleted
