ETABS nonlinear dynamic analysis
ETABS nonlinear dynamic analysis
(OP)
Hello, I'm Henry from Philippines
I'm currently working on a project and i have to evaluate the seismic performance of my structures.
I placed nonlinear hinges on my model and run a time history analysis.
my problem is that ETABS does not recognize the nonlinear hinges i placed. the hinges does not appear to have an effect on the result of the displacement due to the earthquake.
does etabs evaluate failure due to dynamic earthquake loading?

However, ETABS does activate the "link" element during nonlinear time history analysis. The way I have modeled this in the past is to use the link element to model bilinear nonlinear behavior, meaning you can model a linear region and then a plastic region. I do not believe you can model a failure mechanism using this element as it is limited to bilinear. However, for the retrofit I have done in the past using ETABS we were shooting for immediate occupancy therefore our performance point was well before failure would occur and this element was therefore satisfactory.
