I suggest a nonlinear dynamic analysis - try DRAIN-Buiilding

Dear Nincy

Yes, you can calculate the ductility and energy dissipation capacity of structures from pushover analysis. I will try to explain it one by one.

1. Ductility

Before starting my explanation, ductility can be referred to any different levels, for example, ductility in the level of curvature, component rotation, component displacement, or overall building behavior. Let us assume that you have done the pushover analysis and one of the most important factor that you need to find straight away is the global building ductility. Ductility itself means the capability of structure to undergo inelastic deformation. It can be calculated by dividing the ultimate roof displacement at failure with the displacement at the first significant yield. Finding the ultimate displacement is quite easy because you will automatically get this point where your model reaches certain failure drift (when your pushover analysis stops or reach certain drift target). The challenge itself is finding the significant yield displacement. One of my recommendation is by trying to find a point of the step where the stiffness of the building drops significantly at the first time. That is the point of significant yielding.

2. Energy dissipation

When you are trying to calculate the energy dissipation of the building, you can calculate this parameter manually by finding the area below your capacity curve (roof drift vs base shear curve). But if you want to find the energy dissipation per element for example. You need to extract the hinge results from output data and calculate the area below the curve for each elements that you want to observe.

I hope my answer can give you an insight about your question. Feel free to discuss.

 Dear Nincy,

we can calculate value of energy dissipation from push over analysis for structures. It's based to structure properties (Geometry, Boundary condition, Applied loads and so on). Thus, I attached a picture file for better perception of dissipation energy concept. 

I hope this file help to you for good meaning of energy dissipation from push over analysis. 

Kind Regards,

Milad

Thank you sir,bt i didn't get the attached file

Dear Nincy, 

I attached dissipation energy concept file again.

I hope that you successful download it. Otherwise sent to me your email and I email this file for you.

With The Best Wish,

Dear and respected all,

i am from an architecture background but understand basics of structure too. is there any proper book where i cab learn to identify relation between ductility and energy dissipation as i want to design a structural wall out of innovative concrete and reinforcement material for my school project. it will be very helpful if i can get the proper guidance to self learn the things and figure it out on my own.

thank you for your attention and time.

Ankit.

Good question.. Please share me the best answer might you trust...
