Thank you for your advice. Hourglassing it was.
I changed the control from viscous to combined (with stiffness-viscous factor 0.5) and the response became stable.
Thanks for your questions.
I used a constant loading rate of 5 mm/sec when generating the cyclic amplitude to avoid inertia effects.
I noticed that all my explicit models have similar results with SG and DI steps up to 12 seconds,
and after that there is some distorted response and the curve...
Dear Colleagues,
I'm doing a cyclic loading of RC column using Static General, Dynamic Implicit and Dynamic Explicit solvers.
Though I have almost similar results for the SG and DI cases, the results are very different for the DE case (see Figure). I've tried to divide each cycle into 4 load...
Dear Colleagues,
I'm trying to make a model of RC prefabricated structure using ETABS software's link elements to model the connection between the elements.
The links are multi-linear plastic with non-linear force-displacement relationship for U1 and U2 directions.
The U2 direction represents...
Dear Colleagues,
Please share your thoughts on the following question.
I'm going to model a Prefabricated Large Panel Reinforced Concrete Building in ETABS and perform Nonlinear Static and Nonlinear Time History Analyses.
The model has the following assumptions (see figure 1):
- RC Panels are...
