  1. ECIV 320 Structural Analysis I Internal Loadings in Structural Members Sections 4.1 – 4.5 Study all examples

  2. Internal Loading in Structural Members Axial Loading P P P

  3. Internal Loading in Structural Members Flexure P M V

  4. Internal Loading in Structural Members Internal Loadings represent the resultant of stresses distributed over the cross section

  5. Sign Convention P

  6. Sign Convention

  7. Internal Loadings at Specified Point - PROCEDURE • Support Reaction • May need to be calculated before Internal Loadings • Cut the Member • Pass Section parpendicular to its axis at the specified point • Attention: Keep all distributed loadings moments and forces in their exact location.

  8. Internal Loadings at Specified Point-PROCEDURE • Free Body Diagram • Hint: Draw FBD of segment with the least number of loads • Hint: Indicate Resultants inPositive Directions

  9. Internal Loadings at Specified Point-PROCEDURE • Equations of Equilibrium • Hint: Sum moments at the section about centroid • Hint: Numerical Results • (+) FBD OK, • (-) Internal Loadings Opposite Direction

  10. EXAMPLE

  11. Example

  12. Example

  13. Shear and Moment Functions for Beams Design ! Variations of internal Shear and Moment along Axis Normal Force is usually ignored Exception: Compressive Axial Forces (Buckling) Use same approach as before but with variable location of section Pay attention to discontinuities of applied loads
