During this week we have continued with a more systematic arrangement of catenary studies in the forms showed in the pictures. This time, the studies where made with a smaller, thinner chain, this would allow us to have a more elegant shape overall.

One thing to note through this study is the realization that when it comes to catenaries is that FORM IS FOLLOWED BY FORCE

Figure 1: We have a simple catenary hanged from two points to create a inverted arch.

Figure 2: Segmental- Chain that is spaced out in different vertical and horizontal directions to produce different forms. The natural effect of gravity is changed as the chains push against each other to produce different tensions against each other.

Figure 3: Superimposed catenary- two chains handed in two directions meet at the middle creating a form that is configured by 4 structural patterns. Although the shapes are structurally bonded, the shape is not altered because of the centered geometry of the arrangement.

Figure 4: Array-An array is a systematic arrangement of objects, usually in rows and columns. The figure shows how the chains are linked at the center and spread out in even spacing to the sides and front and back, creating an umbrella shaped arrangement that meets on at the origin.

Figure 4 Side: Array- This figure shows the side view of the Array version of the form

Figure 5: Attached- One smaller chain is attached to a parabola to distort the natural form that is shaped from the gravitational pull. The smaller chain slightly pulls the parabola to the side creating a small distortion in the flow.

Figure 6: In Figure 6 another chain is added to the right side that causes more distortion to the central parabola causing tension to be shifted to the sides.

Figure 7: In the figure multiple chains are attached to the model to create distortion in all directions of axis instead of only one left or right. As the chains pull each other in different areas it creates unique forms and curves.

Figure 7 Side: The side view shows the distortion in all directions. As you can see the original flow of the parabola is in multiple axis’s.

Figure 8: This started with a series of catenary extensions that then where linked or attached according to our types. By linking this 4th element to the center of the catenary extension, there is another branch of a linked type that forms to give us this overall shape.

Over the course of this week we have began a systematic arrangement in the form of diagrams as well. We have begun to identify through a grid diagram the type of shape and possible ramifications through this system. This will allow us to easily identify catenary types and shape. On the physical models we have determined that the forms to be evaluated will be saved and documented accordingly

The diagram process we are working on now involves the length of the chain as the spacing between them, the goal is to standardize the process as much as possible in that way archiving and recollection for reuse is processed quickly.
