Stiffness Method | Lecture 4 Local to Global Stiffness Matrix + MATLAB & Octave Coding Tutorial

📚 In Lecture 4 of the Stiffness Method series, we show how to assemble local element stiffness matrices into the global stiffness matrix for a complete structure, step by step. In this lecture, we cover: ✅ Defining nodes, elements, and degrees of freedom (DOFs) ✅ Writing local stiffness matrices for beam elements ✅ Relating DOFs to the full system stiffness matrix ✅ Assembling multiple elements into a global matrix ✅ Step-by-step calculation examples ✅ Coding the global stiffness matrix assembly in MATLAB and GNU Octave This lecture builds on the bar and beam element stiffness derivations (Lectures 2 and 3) and shows how to combine them into a full structural system. This is only for elements where the local and global coordinate systems coincide. We will incorporate rotation in the next lecture. 👷‍♀️ Delivered by Dr Margi Vilnay – Senior Lecturer in Structural Engineering, Chartered Engineer, and Senior Fellow of the Higher Education Academy. 📺 Watch the full Stiffness Method playlist here: http://bit.ly/3VuvFfk 🔔 Subscribe for the complete series and more tutorials in structural analysis. #StiffnessMethod #DirectStiffnessMethod #StructuralAnalysis #GlobalStiffnessMatrix #FiniteElementMethod #BeamAnalysis #CivilEngineering #StructuralEngineering #MATLAB #Octave #EngineeringStudents #EngineeringTutorials
