Hi all
I am modeling a truss in fire conditions, using ISO 835 fire for it. Now I have included some imperfections on the braces(L/1000) and I would like to know how to run this type of analysis(RIKS)
I used normally two steps, one to define the load on my truss and the second to import the temperatures as a predefined field. At this moment I do not know ho to modify my model steps in order to reach the solution. My temperature analysis takes 30 min and I cannot add time to a riks analysis
