Instructor note: A preliminary result is a number with a drawing behind it. If you cannot draw it, you have not computed it.

Learning objectives

  • Execute the discipline preliminary calculations defined in the methodology
  • Interpret preliminary results against design criteria and governing codes
  • Produce the required site layout, plan and section graphics
  • Document assumptions, load paths and limitations
  • Explain what the preliminary results mean for the proposed design

Lecture topics

  • From methodology to first results
  • Preliminary sizing and rules of thumb
  • Gravity load paths versus lateral force paths
  • Required graphics: site layout, plan and section drawings
  • Presenting results in tables and annotated figures
  • Sensitivity of preliminary outcomes to assumptions
