Brief:

Amend the components in a simple truss like structure and describe how the forces flow different in your structure.
(Make components by joining elements in rhino and working with releases)
Note: this is not about which one performs better, as adding in releases always makes the structure weaker – but is MUCH cheaper to build and represents a more realistic structure as the length of members in broken up.
Work on one (or similar to one) of the following grids:
1. Toyo ito Serpentine pavilion London
2. Birds nest – Herzog de Meuron
3. Piramide (reciprocal) – Luz_secret graden party_structruremode
4. Tods Toyo Ito
6. cctv tower grid
etc.
_1 Run fully fixed analysis – extract forceflow by looking at Nx and Ny
_2 Make 2 sets of components and compare how forces flow different.
_3 Do you want it uniform distribution of forces, or a few that take a lot of load?
You can then also use the optimise cross section to get the right section size if you want.
1. Is there a hierarchy, like primary, secondary or tertiary elements
2. Do we have on or multiple types of components.
3. Make sure they form a stable grid (i.e. 3 hinges or 3 hinges and a fixed.

The supporting frame is provided by the intersection of the mesh which is derived from the extension and folding of the lines. For materialization of all the lines there is chosen for a minimum size of steel flat.
Each of the borders of the turning squares from the algorithmic pattern are underlined and made thicker to act as main structure, the secondary structure is made by the extension of the lines from the pattern. In total we distinguish three different level of thickness in the pavilion; these different levels of thickness express the catalytic behavior of the geometry. We distinguish the main structure for large spans, the main structure for shorter spans and the lines which are forming a net of stability. The chosen material for the lines, are actually too weak to span much distance. But due to the density of crossing lines which acting as support the weakness of the material is easily overcome.
Due to the need to solve some local force problems, there are made several modifications to the pattern. Firstly, in order to make the structure in the centre of the pattern lighter and stronger, they changed the ratio from (1/3 – 1/2) to (2/3 – 1/2). Secondly they eliminated some ribs for making larger openings and entrances. Thirdly, they transform sometimes secondary structure in the roof, to main structure in the façade, in order to provide more strength to this façade. A fourth modification is made by adding an extra structure for the support of the glazing in the centre of the pattern.

ANALYSIS
In order to understand the change of behaviour in force flows it is necessary to complete a comprehensive analysis of the entire pavilion as a system rather than isolating a specific component of the grid as we have done above.
Therefore, the following pages will analyse the overall structural system of the pavilion through the isolation the different load cases [GRAVITY, VERTICAL, HORIZONTAL] as well as an analysis of the total amalgamated loading conditions.
Through this process we can then start to target specific improvements for the optimisation of the overall structural design of the pavilion.
