PA R T B R E V I E W BIOMIMICRY
A strong value of the CERES park seen through many of its existing structures is this notion of biomimicry which we wanted to incorporate into our shading structure. The tree is the most notable shading system in nature. There are many different species but the fundamental core behind the structure of every tree is that it has roots which anchor it into the ground, a trunk to add strength and support the canopy, and a canopy for shade. Our intent is to incorporate a load bearing structure starting from the ground which interconnects with and in turn supports the shading system above to ensure a structurally sound system that performs to our criteria. The flower has the same core system as the tree - but what is key to many flowers is their colourful nature which attract birds and insects for pollination. Our intent is to have a colourful canopy to attract children as they play, letting them become birds and bugs beneath the structure. We want to incorporate the notion of biodiversity within our form so a strong idea is to use a flowering climbing plant which would not only attract children, but real birds and insects to promote the cycle of life. This would also enhance our ideas of offsetting biodiversity as the sustainability and ethics behind this approach line up with the values of the park and could potentially promote education on this topic to young school children and act as an interactive example of it.
PA R T B R E V I E W M AT E R I A L I T Y ISSUE: Client expressing strong desire for recyclable materials presents a supply issue for us. We require a design whereby the exact width/length/ finish quality of the members is not determinate of the final design outcome. SOLUTION: GHG recycled timber yard: A depot for recycling used construction timber that come in bundles of high quality off cuts.
DESIGN OUTCOME: A pattern of timber beams in variable lengths optimised structurally through grasshopper.

Butt joint branching habit
PROTOT YPING CONNECTIONS OPTION 1 NOTCHES
Conclusion = would be used better in conjunction with another connection type
+
Cost = none Equipment = power saw
-
Rigidity = poor Time = high (15 minutes per member) Skill level = intermediate Labour = intensive
PROTOT YPING CONNECTIONS OPTION 2 ROPE
Conclusion: option for further bracing element plus aesthetic feature
+
Cost = $120 Equipment = polypropylene rope is stabilised against UV radiation; unaffected by water; rot resistant; lightweight (suitable for the outdoors) Time = low (3-5 minutes per knot) Skill level = easy
-
Rigidity = moderate. Dependant on knot tying skills
PROTOT YPING CONNECTIONS OPTION 3 SCREWS Conclusion: should use in conjunction with another element as it is cost effective
+
Rigidity = high Cost = $110 Equipment = screws, drill Time = 30 seconds per screw Skill level = easy Labour = non-intensive
-
There is nothing holding the members together if the screw were to loosen so it needs further bracing. Industrial looking
PROTOT YPING CONNECTIONS OPTION 4
DOWELS Conclusion: aesthetically pleasing connection type and a way to use the same material for the whole structure. Do not need any further bracing.
+
Rigidity = high Cost = $100 Time = 5 minutes per connection

Equipment = power saw/hand saw, drill, hammer, Skill = medium Labour = intensive
PROTOT YPING CONNECTIONS OPTION 5 NUT +

The ‘Displacement’ option colors the beams based on the distance they move under loading.

The ‘Utilization’ and ‘Axial Stress’ options colour the beams based on how much stress the beams experience under loading. Utilization’ expresses the stress in terms of its percentage of the maximum stress capacity of the material (this is based on the material properties specified for the beam). Utilization numbers can be used to check whether the elements of the model fit within the margin of safety required by a design. A utilization number higher than 100% means that the element is likely to break under the specified load. In our visualization the utilization of each beam is represented by its color, with white beams experiencing the least stress, red beams experiencing a high compression stress (high negative utilization) and blue beams experiencing a high tensions stress (high positive utilization). Minimization of the maximum displacement of the model, or the maximum amount that any element of the structure moves under load. While all structures deflect under loading, there are typically design limits for how much the structure can move.

Effects of altering the number/density of beams
OFFSET BIODIVERSITY H A B I TAT Creating habitat. Drawing from Olivia’s Part B with the trailing ivy tendrils, we propose the inclusion of a climbing plant that will not only assist with human needs by creating in-fill for the structure to provide additional shading but also serve the animals of CERES by providing a leafy green canopy and additional habitat. This concept was borne from the presentation we were given in class on the topic of offset biodiversity. We applied to the concept to the scale of the project and in doing so fused our structural and theoretical themes.

B A JE E RANG ...meaning ‘tree’ in the language of the Wurunjeri people- the original owners of the lands upon which our structure stands- our branching tree-like structure represents the unison of animals and humans coming together for protection and habitat under one structure. The pavillion is not only theoretically reciprocal but also structurally, using 143 timber members ranging from 0.7-3.0m. Using nuts and bolt connections to secure them each piece of the structure is integral as they rest upon each other in a symbiotic relationship. It is both a figurative and literal reciprocal structure that is highly functional, environmentally conscious, thoroughly considerate of its context and user and has a deep connection with the values of CERES.
