Nonlinear Truss System Analysis

This lecture covers the nonlinear analysis of structures, focusing on event-to-event analysis using the displacement-controlled Newton-Raphson algorithm. Topics include initial definitions, force-displacement response computation, and the displacement-control method. The instructor explains the constrained displacements, resistance forces calculation, and tangent stiffness determination. The lecture concludes with a comparison between the displacement-control scheme and the Event-to-Event solution.
