Калькулятор фермы

Operating procedure:

1. Step 1. View of the farm. Select the desired view of your farm and click on the next step.

2. Step 2. The geometry of the farm.

a. Set the farm schema. In this step, you can change the location of racks and braces for different lengths of trusses.

b. Set span farm L

c. Set the height of the truss H or angle a

d. If necessary, you must specify the height of the truss on support H1

e. Click on the next step

3. Step 3. The load on the farm.

Set the concentrated load on the farm nodes and click on the next step, or select "Set Area Load" and set the distributed load to 1m2 and step between the farms. The concentrated load P on the node is recalculated.

4. Step 4. Section and material of the truss.

a. Set the truss material: steel or wood

b. Set the cross section of the truss elements and the class / grade of the material of these elements (if necessary, you can click on the "for all" button and the cross section / class / grade in the 1st line will be duplicated for all the rows)

c. Click on the next step

5. Step 5. Links. According to the figure, place the points of detachment of the nodes from the plane of the truss. Unleashing out of the plane can serve as a link between trusses, and runs

6. Step 6. Calculation result. Click on the button "Calculation"

For reference:

- the density of the tree is 500 kg / m3

- steel density - 7850 kg / m3

- all nodes are hinged trusses

- truss supports - hingedly motionless on the left and hingedly movable on the right
