A1. Form-finding of Simple Shell

We will use Thrust Network Analysis to create a barrel-shaped shell, with a crease in the middle for architectural expression. The tutorial will introduce you to how to start from a Pattern to create a FormDiagram and its dual ForceDiagram, then to calculate horizontal equilibrium and vertical equilibrium. Last but not least, to modify the diagram to create a crease.

Here are the steps, which will be explained in detail in the following pages.

1. create pattern.

2. define boundary conditions

3. create FormDiagram

4. create ForceDiagram

5. horizontal equilibrium

6. vertical equilibrium

7. modify diagram
