PROPOSED STRUCTURAL FRAMING & FACADE TREATMENT From the previous prototypes, we learnt that it is impossible to allow the skin membrane to move in a flexible way when there is a wind impact if we connect it to rigid structures. Similar to the precedence of the “Inflatable Air Dancer”, which at least one side should leave freely. Thus, we came out with the idea of using tensional springs to hold the skin membrane to rigid frames. This allow the skin membrane to move within the limit of the tensional spring. When wind blows onto the surface, the tensional force will pull the skin membrane, hence, the channel will reform. When there is no wind, the spring will be at its equilibrium state. The circular frame acts as the anchor point of the form, it links the skin façade to the spring.
In the physical proposal prototype, the skin membrane is not flexible enough in respond to wind blow. At first we thought by changing a more suitable material, we might can get an ideal result by the connection half-cutting along the edge. We even alter the quadrilateral mesh panels to tetrahedral shape. However, this proved that the half-cutting method would still unsuccessful due to its inflexible connection. Hence, we tried connect the tetrahedral mesh panels with the double tape as shown. This alternative comes out with the result that we want. In real world, we will explore some flexible and elastic joinery in order to connect the panels of the sculpture.
