Project 1

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

Procedure:

Open the RFEM software and input the required settings

Set the units to metric system

Tick the Form Finding option

Insert the nodes at required locations

Connect the lines with nodes

Assign the Nodal Supports

Assign cable material to all the lines

Assign the surface to the membrane using Quadrangle surfaces

Assign the material to the surface

Give the Othotropic Membrane properties

Apply the prestress of 0.8 KN/sq.mm on the conical as well as the connecting surfaces.

Change the local Axes of each surface

Now Go FE mesh settings and apply Triangular Mesh

Gloabal Deformations

Internal Stresses

Principal Stresses

Axial Forces

Support Reactions
