Currently i am working on quantitative assessment of energy dissipation from structural member under seismic loads in low rise building.
Dear Basanta Neupane
The correlation between the energy dissipated in a structural member and its deformations may be numerically assessed by carrying out regression analysis on the data from a statistically large set of nonlinear dynamic analyses.

Have you checked the Park & Ang damage index (DI)? It takes into account the effect of maximum deformation and cyclic loads and has been used for structural elements failing in flexure:

If you have the force-deformation graph, you could consider the area under the force-deformation linear-elastic segment as a measure of energy absorption and the plastic region as the energy dissipation mechanism.
