Coating of production building by metal trusses - exchange rate

1. Design Input

The covering of the production building is designed for steel trusses. Trusses are installed on the walls of the building. The dimensions of the building in plan, thermal operation, construction area by snow load and other data are given in the task.

a. The length of the building in the axes is 60 m;

b. Truss span - L = 24 (m);

B. Truss pitch - B = 6 m;

d. Truss support height - ho = 1.4 (m);

The slope of the upper girder belt i = 10 (%);

e. The roof type is cold;

G. Snow load area. ӀV

Along the length of the building, trusses are placed on walls, as a rule, in increments of 6, 9 or 12 meters. The extreme trusses are offset from the wall axis by 500 mm inside the building.

Transverse connected trusses in the planes of the upper and lower belts are installed at the end trusses of the building, as well as at the trusses in the area of ​ ​ the temperature block provided for in the structure of the building with a significant length, and are repeated after 4? 6 steps of the trusses.
