Influence Line Analysis for Statically Determinate Structures: Shear & Moment Calculations

This lecture explores the influence line (IL) methodology for analyzing shear and moment in statically determinate structures. Part 2 focuses specifically on understanding and deriving ILs at designated points (B and C) through group work exercises. Examples include determining internal forces in truss members and calculating moments at various joints, including points D and C under different load cases. This comprehensive study enhances analytical skills necessary for structural engineering design and assessment.
