Week 1: Compression

Measure out the space required to house the toy Alternating layers of brick to dissapate load equally to the layer below. A beam reinforced with elastic bands for tension is used to close off the tower. The tower is then slowly turned into a circular shape to support a big dead load The week’s activity is to build a tower with compression, which is by layering bricks on top of one another. Using the weight of the brick ontop, the tower becomes very stable and capable of withstanding a large dead load.

By alternating layers of bricks to seperate the load, there can be large gaps in the tower without collapsing the tower

Week 2: Frame This week’s activity of building a frame using balsa wood sticks relates to the readings in terms of different trusses as well as the buckling of long materials. Through building the towers, it also become clear that the cross sectional area of the material contributed to the strength. The group that only cut the balsa wood into 17 pieces has thicker pieces and the resulting structure is shorter but stronger, with no buckling happening at all. The group with precisely 40 pieces of balsa wood had thiner pieces. More buckling occured and the structure of the truss becomes very important.

All groups decied on a triangular base to maximise material efficiency while providing a stable base for the tower

The group with 40 pieces (bottom) experiences more buckling compared to the group with 17 pieces (top). Photo taken while attempting to attach both tow-

Trusses becomes important for the groups with thin strips to prevent buckling. The technique is bracing each vertical component with each other.

Th structure becomes stronger if tapered off at the top, However This means it won’t be able to carry any load

Week 3 reading notes -Clay bricks expand, while concrete blocks contract. -Masonary are strong in compression -Millimetre is what is used in working drawings -Floor plans are usually drawn at 1200mm high. -Dead loads are usually the weight of material itself -Live laods are moving loads including human, water, snow, wind, and earthquake -Forces involved in a building includes lateral, shear, tension, torsion, compression
