  • Building Length.

Distance between the both end wall columns or girts (whichever is greater) is called building length.

  • Building Height
Clear Height – From FFL to bottom flange of main frame rafter.
Eave Height – Distance between FFL to the top of outer point of eave purlin.
Ridge Height – Distance between FFL to peak point of the building.
  • Roof Slop

It is horizontal angle of roof. Roof slop can be vary but generally 0.5 : 10 to 1.5 : 10 is used considering the economical and aesthetics.

  • Bay Spacing

It is the distance between two frames (Length wise).

  • Primary Framing.
