Week 1 Studio session activity report Theme: compression Load path diagram #Principle: the applied load at the top gives a compression to the loads under it. This strength is delivered continuously to each where the structure is formed and supported. Forces are formed by factors of direction and scale, and each force have an opposite force to keep stability. As shown on the diagram, the force of compression is delivered to the ground which the feet of this structure are. While the ground has also generated a force back on feet to keep it stable. #Reference link https://www.youtube.com/watch?v=y__V15j3IX4&feature=youtu.be https://app.lms.unimelb.edu.au/bbcswebdav/courses/ENVS10003_2014 _SM1/WEEK%2001/Basic%20Structural%20Forces%201.pdf
Studio Activities Material: a kind of Timber wood which is a composite material, seemingly baned in some countries.
Activity requirement #to build a tower as tall as possible, and with possible few material. #the tower should be able to accommodate an object, (say, it is a little toy elephant in this case, which is supposed to be able to move in and out.)
Key points, aim #to get information of construction concept, #block laying techniques
Initial plan #initially, we planned to build a tower with concrete basis of a round shape, subsequently with blocks placing on. We assumed the diameter of the round become diminishing as the tower goes higher.
Barrier/ Conflict #as the â€œconstructionâ€? going in process, at the rather beginning we changed our idea to make the basis a square. Followed by a rather rectangular structure
#another rather frightening part of this construction is to leave an entrance for the elephant to be accommodated. By referencing other groupâ€™s example, we learned the layer at where the entrance is Much more diverse than other side
# In case of preventing the higher layer of the tower is leaning to fall, we fixed with other several blocks to support. While, later on we find it is unnecessary for the concrete load path.
As the diagram shows, the side by side blocks, as a system of load path have hold on the weight, the number of the blocks is more than other layer. Thus every individual block has load on smaller force.
Finally, we managed to take away blocks from the model, amazingly we find the model still stable after taking away a lot of them. The load path has shown its strength.
Glossary #Masonry, is bricks or pieces of stone which have been stuck together with cement as part of a wall or building. Like a pyramid.
#Reaction force, when one object apply a strength on another object and keep stable, the other object must be having apply a strength back on it.

Week 2 Studio session activity report Theme: Frame Material: Balsa Wood stick Task To build a frame structural tower with balsa wood stick and glue. # pay attention to the joint.
Plan and in practice # a concrete basis to support the tower where the podia is tightly fixed. *difficulty__ glue stick does not work well on the slippy surface of the balsa wood stick. # a back bone should be going through the whole structure as a support, attached with other several sticks to be supporting the construction. * problem: still the glue, we substituted with tape, while the take will cover the surface of the stick, thus it shall be very hard to bound many stick at the same level of a stick.
Frame Analysis #connection from the pedia to the main trunk, in order to make more stable structure
#long podia, stretch out to spread the weight
Problems # although we took the height of the tower into consideration, the podia we made, which was later on found still not sufficiently long enough to have a stable structure
#lack of preparation of material. Thus we could not efficiently connect the sticks
Comparison with othersâ€™ idea #typical stable and material-saving structure, with stable triangular cross section and neat structure.
Glossary #structural joint 1*Pinned joints theoretically allow rotation but resist translation in any direction. 2*Fixed joints maintain the angular relationship between the jointed elements, restrain rotation and translation in any direction, and provide both force and moment resistance. 3* Roller joints allow rotation but resist translation in a direction perpendicular into or away from their faces.
