Block Tower is making process. Jiayun Ken, Campus 2014

01_Studio Report Activity ‘Compression’ (Build a block tower) PROCESS 1 Plan A: Build the tower as a hollow Cylinder without.

Consideration: Height- Easy to put the dog insider, but hard to take the dog out of the tower.

Plan B:

While building the basement, we compact the block as close as we can to make the base solid and strong. We left a blank space for constructing the dome gap later.

The process of making the basement was smooth without risk of collapse, as the structure was stable and balanced.

Build the tower with a hollow Cylinder basement including a dome gap, then polymerize to the top.

Consideration: Danger- Easy to collapse while closing the dome.

PROCESS 2 processing the close up While I was for the dome gap with my group members, we started panicking.

During the interpretation of Compression, (Fowler, personal communication, August 1, 2014), if the objects has nowhere to apply the compression, it would collapse.

When we started to put the last block on the big gap between the blocks down the bottom, we decided to fill the gap by compacting another two blocks to keep it stable. If we only put one block on the top, the live load would directly applied on the edge of the block on the edges of the blocks on the bottom, according to the compression forces, the structure would be in risk of collapse.

Therefore, what we did is to disperse the compression forces on the other two blocks to keep it solid.

While we were closing up the gap, we had considered about where the load applied and where the force was going to transfer. Therefore, firstly we built up the surrounding of the gap around and around.

PROCESS 3 After we finish the tower, we started the process of deconstruction.

D.C_1When we randomly took one block out of the whole structure, the whole structure stayed still. On the other hand, inspired by the e-learning retrieved from, https://www.youtube.com/watch?v=s4CJ8 o_lJbg&feature=youtu.be. According to the material of the block, the block is made of soft wood which is not strong or stiff material like concrete or steel, but light and isotropic material depending on force. Therefore, the load applied on each block can be flexibly transferred through in different direction without taking the most direct rates down to the ground in order to keep the structure stable.

D.C_2 Then we started to took the one block around the dome gap out of the structure.

It then collapsed. Without the block, the load force applied from the block on the top had nowhere to transfer the compression force. Thus it collapsed.

PROCESS 4 By comparing our block tower with the tower from other group, we found that they used different way of building method to construct a stable structure. This tower was also built with a gap on the bottom for putting the object, but in a seemingly cliffier way which made it more parametric style and higher than ours. Despite of that, the structure is still stable. Comparing to other group’s tower, our tower has smaller knuckle radius so that it seems flat around the nook.

As long as the load applied on the blocks, the compression would push on the structure and the particles of the material compact each other (Newton, 2014). However, the higher the tower is, more compression forces on the ground and more reaction applied in order to make the structure stable

Basic Structural Forces (1) E-learning, 2014

E-learning, 2014

E-learning, 2014 Tension Forces – stretch &elongate the material. When external load pulls on the structural member, the particles composing the material more apart and undergo tension.

Amount of elongation depend on the stiffness of material cross sectional area and the magnitude of the load.

The applied loads has reaction to make the whole structure become stable. The reaction is one of the fundamental laws of the structure is that as equal & opposite to the applied loads in order to be stable.

Compression Forces – Produce opposite effect of a tension force. It results in shortening of the material.

When external load pushes on a structural member, the particles of material compact together.

To present larger elements in smaller format and also in the opposite way as well as for practical reasons.

E-learning, 2014 Strength -strong or weak (Steel stronger than timber) Stiffness (Hardness) -Flexible (Rubber & Carpet) Stiff (Concrete) Shape - monodimensional (linear)/ bi-dimensional (planar)/ tridimensional (volumetric) Material behaviours isotropic/anisotropic (steel, metal), depend on force Economy & Sustainability - How expensive, how durable/ available?

- What impact it has on far need to be transported? how can be used?

Assimilating Knowledge Referred to the studio activity. When a live load applied on the object (block) which is made of weak, stiff and anisotropic material such as soft wood or timber. The compression force would apply on the blocks underneath, and the force would transfer through the column and beam in different direction. However, the load is not transferred through the most direct rates down to the ground.

The applied loads has reaction which keep the whole structure stable. The reaction is that as equal and opposite to the applied loads which results in steady. Moreover, the higher the structure is, more compression forces are applied on the ground and more reaction are applied so that the structure would be stable without in risk of collapse.

03_Glossary Appendix 1. Dead loads – static loads acting vertically downward on a structure (Ching, 2014, p. 2.08).

2. Load Path – the direction in which each consecutive load will pass through connected members. The load applied on would be transferred through the column and beam in different direction (load path).

3. Reaction Force – The applied load has reaction. The reaction can make the structure stable. It is one of the fundamental laws of the structure is that as equal and opposite to the applied loads.

4. Beam -a long, sturdy piece of squared timber or metal used to support the roof or floor of a building.

5. Masonry - is the building of structures from individual units laid in and bound together by mortar; the term masonry can also refer to the units themselves.

6. Point Load - is a load which is in a specific location on a structure. (Even though it is usually really not applied at a sharp point)

7. Settlement loads – imposed on the structure by subsidence of a portion of the supporting soil and the resulting differential settlement of the foundation (Ching, 2014, p.

2.08).

8. Compression - a characteristic of mass construction (vertical /horizontal) - Opposite to tension

9. Force – Ching (2014, p. 2.11) notes that it is the definition by line of action, sense and magnitude (size). It also influences produce change in shape or movement of the body. It has vector quantity processing both magnitude direction.

10.

Tension Forces – stretch elongate the material.

According to (Ching, 2014, p. 2.11), when external pressure pulls on the structural member, the particles composing the material more apart and undergo tension. Amount of

elongation depends on the stiffness of material cross sectional area and the magnitude of the load.

11.

Compression Forces – Referred to (Ching, 2014, p.

2.11), the compression forces produce the opposite effect of tension force. It results in shortening of the material.

When external load pushes on a structural member, the particles of material will compact together.
