Week 2 journal This week’s tutorial can be divided into two parts. Part 1 is “case study site visit”, for this part we visit four buildings in campus. Part 2 asks us to build a structure by using some timbers and wood blocks, this structure must good at against loads from top.

Here is my report for part 1.

All of these four buildings have new parts build basic on old buildings. These is the key point for this task.

The first building is eastern precint student center.

This section is built at the gap between two buildings. Because the left side one is taller than the right one so we can clear see a slope in the picture above.

The whole structure is shown blow.

The constraint for this section is the old buildings, this section can’t build bigger than old buildings.I don’t learn any word to describe construction type and structural system the only thing i can say is this a kind of type which fills gap between buildings and connects both buildings together. Materials use for this building are: steel frame, glasses, bawten, blue stone and plywood.

The highest part of this section is about 9 meters and the the lowest is about 6 meters.

The second building is MSLE building.

This section is same principle as first one. It is a line between building as well. But there has some differences because the old buildings are not same structure.

This part is interesting, because the builder want to entire to the second flour of left side building by using the stair of right side building, so he designs this section.

This section has same construction type and structural system as first building but materials are not quiet same. Materials use for this section are concrete glasses stainless zinc conteliver scam stell and cricker. The old buildings decide the shape for this section and this section can’t build out of old buildings.I still like the design he uses for link two buildings by using the old stair.

The third building is Queen college extention

This is complete different type from last two. This part is an extention of old building. The boundary for this section are roads behind and the old building, so it shapes as the way we see today. This section uses one wall from old buildings as one side and build another side, so it makes an open-air area with wall at three sides around. Materials use for this section are timber concrete glasses and metal sticks. It is just a simple structure which build for extending area.

The fourth building is Ormond theology center reception

This area is the end of a long building and basic on it’s use, it designs as the way we see.

The boundary for this section is the building beside, this section should have same width as the building beside. The link to other building is the door inside which allow people get into the building beside. This section is more like a steel frame with glasses and wood for wall.

Materials use for this section are copper sheet timber in concrete glasses and steel. Some parts of this section interest me. The first one is the pillar.

The pillar is built by using timber in concrete, i don’t know the name of this new building material, but i guess purpose for this material is more light.

Another interesting thing is the steel layers.

I am not sure what are these steel layers use for, but i guess they are using to fix the steel rod.

Without these layers the steel rods may easily curve.

The next activity I do during tutorial is construction workshop. The task for workshop is using some different size timbers. We use these timbers to build a structure and use it to against load from top.

My group is group 3. We have one 120*3.2*90mm ply and three 1200*35*35mm pine.

The pine is good at tension and compression so it can be used to build the base of our structure.

The thin plank is easily to ply but if we put it stand up it is good at compression.

We use some tools as well, they are nail screw hammer saw and screwdriver.

Nail uses to tail timbers together.

Screw uses to tighten timbers, timbers will be more tight than using nail.

Saw uses to cut timber.

www.bunnings.com.au Screwdriver uses to tighten screw into timber.

The images shown below are the design from our group. I can’t draw them, so I just use photos.

Top view

Whole structure The reason we design like this is because the thin plank is good under compression when it stands, but it still too thin, so when a force compress it, the area under force still too small which means the force will bigger. So we design to put two timber at both sides of the thin plank, that increases the area under force which may disperse force. I think the failure for our design is the top part. The two timbers don’t have same length. When we do the text the long timber rotates and distort the thin plank.

This design is really good design. They build two triangles and trangles are most tough shape. But the failure of this design I think is when the triangles fail and the force touch thin planks, the touched area is really small, and thin plank is easily break.

This group’s work is not very well. It does’t make sense for me. Anyway, if I design by using these materials i will cut the timber into two. And put at top and bottom.

Mostly like this.

For “ On site”

This is concrete line with poles, i think it should be used for fixing the part of building above. This belongs to foundation system. Materials use for this section are concrete and iron.

This part is foundation system and floor system. Wood structure are probably the base of floor.

Because the time, the worker does’t talk to us. Materials use for this section are concrete iron and wood.

This part seem like almost finish the foundation system. This step should before last picture and going to last picture. Materials use for this section are concrete iron and wood too.

This picture shows the frame for the building. The steel frame shape foundation system. Materials use is steel.
