WEEK 1


In the lecture we used a page of paper to build up a base for holing a 5kg brick. As we know, the base which is shape of triangle will be strong than other shape of base. Hence I built up a base of shape triangle. After putting the From the top: from the side: brick:

In the tutorial we need to use a great amount of block to build a building as high as we can. And we also need to leave a space for the horse to go in. That’s mean we need to make sure that the building should be firm and tall. The base of our building:

we try to make a round base to make sure the surface touched the ground is big enough for holding the rest of the block.

use two standing block to increase the height of the building.

-1-


We built the block as a stair, it can be strong enough to hold the pressure. Because each block relate to each one hence it will be difficult to break it. The short is that if one block is broken other will be affected as well.

Here is the outward of our building. The outstanding block will be the weakness. Its very easy to attack our building if one of outstanding block has been removed.

-2-


Inside look

From the top.

The open space is the door for the horse to go inside.

-3-


This was the tallest building in our tutorial. It used the shape of honeycomb. It held the structure more stronger. Each box which placed on top of the building was around 10kg. we put six boxes on it but the building still can hold it.

-4-


WEEK 2


In this lecture we need to use two straws and a box to build a base so that it can support heavy item. A student sticks the straw from the four sides so that it could balance the box. Unfortunately its too weak for the straw to hold the heavy item.

This student uses four straws to make a shape of W. And it even has a support point in the middle of each straw. Because the straw is too weak so it still can’t hold the item.

-5-


In the tutorial we cut a piece of wood into 20 slices. We need to use these 20 slices to build up a tower as high as we can. We choose to build a triangle shape base: We used tape to stick each slice together. For the base is the most important part of a building. If the base is not firm enough it will affect the rest of the structure. And all the slices should be in one horizon.

We stick the pillar part between the angles so it has a support angle.

-6-


First floor of our tower

If there is no support point in the middle the tower will not afford great forces which act on it. Hence we used another three slices to support each base then we even used three short slices to support from the middle of the pillar.

-7-


At the end, our tower has been built up to floor three. The last part which only has a slice sticks on it just to increase its height.

Due to our rough handwork our tower has lean on one side. So we need to give it a support opposite it. That’s why at last we stick another slice to the base.

-8-


When we started to act forces on the tower we can see the one without middle support is being twist but the base still held together. The weak point of the tower is every middle point of the slice.

The bend part is the middle of the slice.

In this week tutorial we talk about scale and how it works: In our group we discuss that scale is a measurement for images, map etc. Scale can help them to find a right size which can fit into a fixed page and convey the idea to readers and clients. Different scale will explore different thing: •Large scale: to show precise detail of a place •Small scale: to contain more information and general ideas about the project Question: how does the information in your drawing set compare to what you observed at site last week? How does the scale of the building compare to the scale of the drawings? How do the architectural and structural drawing differ? The information in my drawing set is more detailing about the plan in the structure and the material use for the building. It also shows the actual size of each room. The actual scale of the building compare to the scale of drawing is most related by the start and end point. For the architectural it may exist some leaks and gaps. The structural drawing is very accurate but the architectural is not.

All the column use to support the truss system. We use wood stick to build the model. Relate to the scale of 1:100 we measured the length on the drawing set then calculate the actual model length. We first made the structure of different section, in the end we stick them together. Due to the inaccurate measurement some of our section has been oversized so the whole structure lean to one side .

For this model, we can see the structure has been supported by the column. In the actual building it built up with steel. And for the wall is concrete and masonry bearing wall which can require reinforcing to handle tensile stresses when it has been acted a strong compression.

This model is similar to the one we made. Its also a truss structure. Which the column is the main element for transferring the load and support the structure.

Detail drawing: It was a waterproof structure because the material used is flashing which can prevent the water dripping into the building. It also use thermal insulation for both roof and windows to trap the heat inside the room. And the use of the acoustic insulation can prevent the noise from the outside. Outside of the building, there is a gap in the handle. It could be the inaccurate size of the glass that cannot perfectly fit into the handel.

For my group. At 310kg our structure started to crack, and the crack was began at the knot where we nailed the beams together. And the knot was the weakest point of the whole structure. For our structure, the first beam was placed in the middle. So the load transfer downward will act most of the forces in the middle point of the rest of the beam. As long as the force act on the structure was exceed the structure will start to crack at the middle point of the lowest beam as we see in the pictures. Its buckling due to tension force. Compression force

Tension force

First group made their structure into a triangle shape which is the most stable structure. “Because the triangle does not easily deform and is able to balance the stretching and compressive forces inside the structure.� (Most stable shape— triangle,2011)

At 420kg the structure started to crack. The cracking point still at the knot where they nailed two materials together.

-59-


Second group’s structure. They nailed all the beam together and use the pine to support it on the side. But it still cracked at the knot due to tension force The third group laid their structure horizontally, it spread the force that acted on the structure. But the force for the wood was exceed and there was no more element can support this structure so it cracked at 280kg.

Comparison between working with actual construction materials as opposed to working with scale model making materials. When working with a scale model we can think about how to make the structure more stable and can afford more forces. After finding the shape of the model and the length that fit the model we start to build it up. With the actual working is hard to measure an accurate length for the timber and it need more strength to cut the wood. As time passed, its enable for us to finish in a limited time. So we just nailed all the materials together.
