Demonstration of SAP2000 insertion-point and end-offset application, including the effects associated with transform stiffness.

Hand calculations

Screenshots

The visuals which follow illustrate the modeling and performance of two systems, one with default settings which transform stiffness to account for insertion-point offset, and one which does not transform stiffness.
