This lecture covers the calculation of stiffness matrices for each beam in the global reference frame, the assembly of the total system, the exclusion of constraints, the resolution of reactions, and the calculation of displacements. It also explains the impact of changing the element numbering and node positions on the structure's connectivity matrix. The lecture further delves into understanding the influence of variables on the connectivity matrix, the equation numbering matrix, and the stiffness matrix. Additionally, it explores the significance of grouping degrees of freedom and the rotation matrix in the context of inclined bars.
