PROJECT 2

1Q. Model of a membrane roof with cables. The modeling, form-finding and create the cutting patterns to the structures.

Answer:

Aim:

Membrane roof model with cables. the modeling, form-finding, and creation of the structure's cutting patterns.

Procedure:

• Make a new project, then add choices for form finding and pattern cutting.
• Make the membrane structure's nodes.
• Link the nodes and lines together.
• Assign the material to the lines as cable.
• After choosing the nodes, give hinge support.
• Assign the surfaces to the cable boundaries and designate a new orthoropic elastic 2D type material for the membrane.
• Enter 1 KN/m as the pre-stress force in the Form Finding Dialog.
• surface material characteristics.
• Proceed to the tools menu, select Generate Cutting Pattern from Cells, and create the cutting pattern.
• Create load scenarios with an imposed load and self weight.
• Put a 0.25 KN/m^2 applied load on the membrane surface.
• Select the results combination from the design limit check by going to the RF-LIMITS module from the data drop-down list.
• For each surface, include the axial force ranges in both the nx and ny axes.
  Use 1 meter triangular meshing to generate the mesh.
