  2. Solving for Capacity FcFvFb

  3. Adjusted Compression • Solve for K • Adjust Length • Determine Size Classification • Adjust Fc • Calculate Capacity • Interpret Results BE 303

  4. Solve for K BE 303

  5. Adjust Length BE 303

  6. Determine Size Classification Short Intermediate Long Not Allowed BE 303

  7. Adjust Fc Short Intermediate Long Not Allowed BE 303

  8. Calculate Capacity BE 303

  9. Interpret Results Ok Not Ok BE 303

  10. Adjusted Shear • Find Shear Force • Interpret Results BE 303

  11. Find Shear Force BE 303

  12. Interpret Results Ok Not Ok BE 303

  13. Adjusted Bending • Find Bending Force • Adjust Length • Calculate Cs and Ck • Determine Classification • Adjust Fb • Interpret Results BE 303

  14. Find Bending Force BE 303

  15. Adjust Length BE 303

  16. Calculate Cs and Ck BE 303

  17. Determine Classification Braced Intermediate Long Not Allowed BE 303

  18. Adjust Fb Braced Intermediate Long Not Allowed BE 303

  19. Interpret Results Ok Not Ok BE 303

  20. Plate Connectors Determining Capacity

  21. Plate Connectors • Determine Load Case • Find Area • Calculate Capacity • Interpret Results BE 303

  22. Determine Load Case BE 303

  23. Find Area Notes: • Plates are only effective ¼ inch from edges. • Wood has to be adjusted from nominal size • Area of plate is divided across all the members in which it supports • Are there two plates? BE 303

  24. Calculate Capacity BE 303

  25. Interpret Results Ok Not Ok BE 303

  26. Deflection & SlopeBeams and Frames

  27. Wood Members • Analyze the Problem • Shear & Moment Diagrams • Write Moment Equations • Perform Summation • Evaluate BE 303

  28. Analyze the Problem • Draw a sketch • Declare sign convention • Apply imaginary load at point of interest • Δx= deflection, apply unit load • θx= slope, apply unit couple • Write governing equation BE 303

  29. Shear & Moment Diagrams ** Standardize Integral Length ** Real Load Unit Load BE 303

  30. Write Moment Equations • Equations require both a length and load • Equations should be based off of your diagram • Unit load diagrams are usually simpler Questions? BE 303

  31. Perform Summation BE 303

  32. Evaluate • Combine like terms • Plug in length and applied load • Plug in E and I • I should be applied based on orientation of member • If not given – look up using charts • If Δxis positive, then Δxis in the direction of the applied load. • Deflection units will reflect the length units • Ex – If length is evaluated in inches, deflection will be in inches • Slope does not have any units associated with it BE 303

  33. Deflection & SlopeTrusses

  34. Trusses • Analyze the Problem • Calculate Axial Force • Fill in chart • Perform Summation BE 303

  35. Analyze the Problem • Draw a sketch • Declare sign convention – T (+) & C (-) • Write governing equation • Make a chart (easier to keep track) BE 303

  36. Calculate Axial Force Assume: • Only axial forces apply • Loading only on joints Find vertical and horizontal components located at each node BE 303

  37. Fill in chart BE 303

  38. Perform Summation Sum all deflections in order to get the final deflection at the point of interest. BE 303
