  Loads.

  We consider two types of loads: 

  - distribution of the outer contour of the overhang load by pulling the curtain q = 600 N / m (60 kg / m);

  - concentrated vertical R = 1200 H (120 kg) applied anywhere in the overlap caused by the weight of installers.
  

  Terms of calculation

  Allowable stresses are assumed equal to the calculated resistances Ry:

  - the mass of farms and horizontal communication - 235 MPa (23.5 kg/mm2);
  

  - Rack - 242 mPa (24.2 kg/mm2);
  

  - deadbolts - 235 mPa (23.5 kg/mm2).
  

  
  

  Allowable deflections [W] are assumed equal to 1/200 of the span.
  

  According to SNiP 2.01.02-85 "steel structures" allow flexibility [A] stands at 150.
  

  calculations of the structural elements only the most tense, and not only on the most favorable load.
