From how to select material, if calculated all say more detail. With his in the bracket design experience, I summarized below and hope to help system power generation industry friends:
Bracket is installed from bottom to top height is 4 m below the solar array. Calculation for blew from the front of the bracket (wind) wind pressure and blowing from behind the stent (wind) wind pressure caused by the material amount of bending strength and bending, buckling of bracket (compression), and the tensile strength and the strength of the bolt installation, etc., and make sure the strength.
(1) structural materials
Selection of scaffold materials, determine the sectional secondary moment IM and coefficient of Z. Most of them use Angle, or square tube.
(2) the illusion load
A fixed load (G)
Component quality (including the border) other GK2 GM GK1 weight + + framework
