    Framing systems

    • A Non-Framing System

    • A Simple Framing System

    • A Larger Framing System

    • Note Similarities

    • Load and Support Modelling

      To understand how the system works, you need to be able to extract a single element and model it in isolation.

      Structural Dissection



    "Load smearing": a double-T example:


    Stack framing vs. flush framing.


     

    Key Concepts

    • Modelling loads
      • Dead Load: Calculation
      • Live Load: Code lookup
      • Environmental loads: Code lookup, analysis
    • Approximation methods
      • Load "smearing" (averaging non-uniform loads as uniform)
      • Estimating loads exerted by supported framing.
        • Tributary Area (a.k.a. contributary area)
        • Tributary Width
