Project Phase 2

 

Part 2A - Photo Scavenger Hunt

Visit a local business, like Lowes or Home Depot, and do the following.

  1. Measure the cross-sectional dimensions of the following items and compare to the values given in NDS Supplement Table 1A or 1B.  If you borrow a tape measure from the Tools department, please return it!  It would be quite annoying to the store employees for 30 people to leave tape measures in the lumber isles and would look bad on S&T.  Which size subdivision does each go in?  
    • one board
    • one piece of untreated dimension lumber
    • one piece of treated dimension lumber
    • one piece of timber
  2. Photograph two or three grade stamps and decode the information (commercial grade, etc) in each.
  3. Photograph the end of one piece of hardwood lumber and one piece of softwood lumber.  Can you visually tell any difference between the two?
  4. Photograph one tight knot and one loose knot.
  5. Photograph the side of one piece of lumber with angled grain.
  6. Photograph the end of one piece of lumber made from a tangential-longitudinal cut and one piece of lumber made from a radial-longitudinal cut.
  7. Photograph three defects and label them.

Find and photograph two or three interesting features of a living tree (or multiple trees).  Where is this tree (or trees)?  What is it that you find interesting (reaction, defect, etc)?

Find and photograph a glulam.  How many laminates does it have?  Approximately how thick are the laminates and does that correspond with it being straight, slightly curved or sharply curved?

Place the photographs and narrative in a Word document (or similar program).  Submit a printed or emailed report (or memo) by class time on Thursday, February 28 Tuesday, March 5.

 

Part 2B - Adjustment Factors

List the reference design values that correspond to your design project (either Phase 1 or a modified/enhanced version of Phase 1).  Determine the appropriate adjustment factors (you can pick ASD or LRFD).  List the adjusted design values for the various components in your design.  Refer to homework problems 4.28, 4.30 and 5.11 as examples.  Submit your results with the above items.
