This test problem demonstrates SAP2000 insertion-point and end-offset application. Also presented are their associated effects, including those of transform stiffness.
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.
