Glossary
Load path A path that seismic forces pass through to the founda4on of the structure and, ul4mately, to the soil.
Tension force When an external load pulls on a structural member, the par=cles composing the material move apart and undergo tension. (Ching, 2011)
Masonry construc=on
A form of construc=on iden=fied by self-‐suppor=ng walls of masonry, e.g., brick, stone or hollow concrete block.
Compression force
Compression force produces the opposite effect of a tension force. . (Ching, 2011)
Beam Sturdy piece of squared =mber or metal used to support the roof or floor of a building.
Tutorial ac=vity: In the tutorial ac=vity, we have divided our tutorial group into small group and we have four people in our group. Our aim is using Medium Density Fiberboard(MDF) to build a tower as a group as higher as possible.
We are star=ng off by building a square founda=on because we think it is the most stable structure.
As the wall goes higher the load path to the ground becomes more heavier. And base on the Newton 3rd law that The law of ac=on and reac=on states that for every force ac=ng on a body, the body exerts a force having equal magnitude and the opposite direc=on along the same line of ac=ons as the original force. So, at that =me the reac=on force from the ground to the wall is the same quan=ty of the force as the wall reacts to the floor.

As the wall raises to a certain level we decide to construct a closed rood. Therefore we change our square structure into circle. That we we can keep a tendency which goes inwards to the center of our tower. However aZer we build couples of levels, we have realized that is not stable and we can not keep build like that. The bricks is keep dropping once we put it on.
Therefore, we find a new way which like the diagram shows we put one bricks on the top of two and keep a inward tendency. Even though, it falls again but it is actually a be]er was to use.
There is a group build a pre]y successful tower with a closed roof by using the a basically shell structure. Their structure is quite stable and they have a balanced their load path so they can put a equal weight box on it.
Week 2
Frame structure Membrane Structure in Melbourne
Shell structure. (Sydney Opera House) Skeletal Structure
Lecture ac=vity
In the lecture, we have understood that with the right structure, a plas=c bowl and some straw, it can hold a thing which might be many =me of it is own weight. And we can also see that triangular structure is very much more stable than many others.
Tutorial ac=vity
In the tutorial ac=vity we have to construct a stable tower using pieces of balsa. We must make sure the tower can stay in place with the forces applied. This is a skeletal/frame structure, we enhanced the structure by placing triangular diagonals within the tower. We started with a square base while we are building we put a support in the middle as a triangular support and make it more stable.
