Strain energy calculation
« on: April 30, 2021, 10:50:51 PM »
My question is a general question and is not directly related to EE-UQ, but I would appreciate it if you could help with this before I start using EE-UQ.

In OpenSees, is it possible to calculate total strain energy of a structure? For instance, in the generic n-story, n-bay example on the OpenSees website (link below), how would we calculate the total strain energy in a push-over analysis?
what would be different if we had concentrated plasticity?,_N-story_N-bay,_Reinforced-Concrete_Section_%26_Steel_W-Section?fbclid=IwAR35Ddo4P8r9B15e13DXaPWNMjwNehnzuvrxpE13PdyXl2w8FeBp9AEBad0

there is no command in OpenSees that directly calculates and returns the strain energy .. you would have to write some script that would loop over all ele and all gauss points and would have to be element specific
