Dear Silvia,
Thanks for your help, but this is a steel member so if we select elastic-no tension material, which other material could use to obtain the part of the diagram with negative slope?

Hi

How can we use one element internal forces (for example moments) in the performance function of a reliability analysis?

Thank you

Hi Hoda Sorry, I saw your message this morning. I had some problems! You know, I couldn’t find special tools in this regard. In fact, it seems that OpenSees don’t show plastic hinge formation automatically like some other finite element packages. So, I think you yourself should determine plastic hin...

Hi, Smitha Thanks again for your time and reply. So, suppose we have a dispBeamColumn element with rectangular (hxb) cross section defined using “patch quad” command, now how can we define h (depth of beam) as random variable? For example randomVariablePositioner 1 -rvNum 1 -element 102 -section 1 ?...

dear friend, Smitha
tanks for your help but I couldn’t find my answer there!. you know, in fact I want to define cross section properties of a member for example depth of a beam as random variable in reliability analysis, so I didn’t see such proper command.

randomVariablePositioner

Hi,
Dear silvia
How can we define the cross section properties (fiber dimensions or area,…) in reliability analysis of for example a frame structure as random variables?
I mean which syntax of randomVariablePositioner command are needed?

Tank you very much
