Hi!
Short question: how can I obtain center of mass and center of rigidiy from a SAP2000 model? (v23.3.0)
Backstory: I am preparing a model of a frame structure with a wall core (stairwell and elevator shaft). In order to do a pushover analysis, I want to model walls as columns (to be able to define plastic hinges). Now to do the structure "justice" I am firstly modelling only the wall core - once with shell elements and once with frame elements to get "comparable" models. Since some walls are L shaped, I have simplified them to one column to which i added modifiers for mass, weight and moments of inertia. Now i'd like to check whether or not the rigidity center is the same in the simplified-frame-elements model as in the shell-elements model.
I will be happy to hear feedback on the short question and the backstory
