Project 1

Aim:

To Perform Form-finding and structural analysis structure of multiple masts.

Procedure:

Step 1:

1) Open RFEM Software

2) Create new file

3) Edit the name of the new model and click ok

Step 2:

1) Click tick mark for form finding option

Step 3:

1) Create a new line

2) set the node

3) Click ok

Step 4:

1) Select the created line

2) Click rotate option

3) click setting option and tick mark the lines between nodes option

4) Edit the rotation angle as 40

5) Also edit the no.of copies as 9

Step 5:

1) convert all the arc line into polyline

2) Click ok

Step 6:

1) Delete all the nodes of the center point

Step 7:

1) Select the member and mirror

2) Edit the axis as XZ

2) Click tick mark on create copy option

3) clik ok

Step 8:

1) Select the two objects and click mirror

2) Mirror the objects by choosing the plane as Y-Z

3) click ok

Step 9:

Assigning of Members:

1) Choose the Y axis view

2) Select all the bottom node of the object and double click it

3) Click members and choose the members as cable

Step 10:

1) choose the material from the library

2) Assign the material as stainless steel

Step 11:

1) Set the 10% of relative sag from the parameters

Step 12:

1) Select the top nodes and double click

2) Apply the material as previous one

3) Change the relative sag to 1%

4) Click ok

Step 13:

Assign the surface:

1) select all the object and double click it

2) Edit the new material

Step 14:

1) check the form finding

Now surface has been applied sucessfully

Step 15:

1) Assign the form finding value as 0.5

Step 16:

Assign the support:

1) Select bottom of the node

2) Assign the hinged support

Step 17:

1) Do the above procedure for top nodes also

Step 18:

1) Set the mesh settings

Step 19:

1) Generate mesh

Step 20:

Run the analysis
