Week 01 Summary

Material

Scale METER & MILLIMETER

Consideration (where&when):

Load Static Loads: structure responds slowly deformation reaches a peak when the static force is maximum. e.g live/dead loads snow/rain loads (Ching, 2014, 2.08)

-Strength: weak/strong -Stiffness: stiff/flexible/stretchy/floppy -Shape: mono/bi/tri dimensional -Material behaviors: isotropic/anisotropic -Economy & sustainability: travel, efficiency

Timber: wood - softwood(sw)/hardwood(hw)

Steel:

suddenly to a structure, rapid change. e.g wind loads

IRON + CARBON = STEEL base metral - iron,aluminum,copper,zinc alloy - bronze, BRASS(most common) UB/UC - universal beam/column Concrete:

earthquake loads (Ching, 2014, 2.09-2.10)

cement+water+coarse aggregate(e.g crushrock/bluestone)+fine aggregate(sand)

Dynamic Loads: apply

Melbourne: bluestone (basalt) Sydney: sandstone

Load Path Diagram

Perth: clay bricks & limestone

The path a load takes to distribute the force evenly to the receptors. This is the most direct route and is met with a reaction force that is equal and opposite - one of the fundamental law of structure (Newton, Clare, Load Path Diagrams, 11/03/2014)

3 Forms of Cons

Structural Forces Definition A force is any influence that produces a change in the shape or movement of a body. (Ching, 2014, 2.11)

Tension forces:stretch and elongate the material.

Compression forces: Shorten the material. Opposite effect to tension

Material MDF (Medium Density Fibreboard) which is made from wood fibre under heat and pressure. They are less expensive and easy to manufacture.

Process & Construction System

In order to accommodate the object(elephant toy) in the structure using the minimum number of the bricks, we began by measuring the length, width and height of the object which was around 350x200x150mm, therefore we placed a square of 6x7 bricks first to ensure the diameter of the tower, and decided to make an entrance of about 15 bricks’ height once we reach enough layers that won’t collapse the structure.

Even though putting bricks vertically would be more efficient at rising the structure, we found it was more stable to place the wider side face down due to a wider area which lower member could connect with the higher member.

Soon after we reach 20layers, a new question came out, when and how should we deconstructe the entrance? To keep the stability while adding some height, our team increased the preasure by adding two layers of clay brick. And by this, the principle goes to structural forces, the increasing loads from clay bricks made it easier to take the small bricks out when them all compact together, plus it shorten the time of deconstruction.

After applied several layers, we found it was creative and faster if we placed bricks vertically as column and doubled it to make it more stable. Later we narrowed the structure to constrcuted a roof by putting higher member on the 1/2 inner surface of lower member. And eventually we started to layer bricks one by one and reached the highest level of the class.

Load Path Diagram

The load path as diagrams show, is simply the direction in which each consecutive load will pass through connected members. The sequence commences at the highest point of the structure working downward to the footing system; ultimately transfer the total loads of the whole structure to the foundation.

Comparison to Other Group

This group has a thicker lower part than ours; the bricks are piled up and construct a very strong support. And the loads from top may transport directly to the bottom then split into various directions then to the ground.

However, the structure rises significantly narrow and creates quite an unstable situation with a sense of inharmony. Though the structure has been built to a certain level without supports around, it will collapses easily by adding small amount of loads or simple quake.
