At the beginning of the construction, we decided to use the combination of 13 bricks as the column

of first floor, and filled the wall with same structure of bricks. However the stability of the

structure is questioned as the first floor is somehow the basis of the whole tower.

therefore on of the member come out with a better idea:

each level of the

column has four

bricks and the

direction of

connecting level is

opposite

The new basis composed by 9

column with 13 levels of the new

structure and (another one is setted

at the position of the animal). This

level contain the most number brick

and widest wall to curry the weight

of the whole tower.

The second level start with a special beam:

The four bricks up on the beam can help strength

the connecting part if the bricks and decentralize

the force to the columns, so that the rubber that

fasten the bricks won’t break and the beam can

curry more force.

Second floor has much less brick than the first, we used the normal wall structure to more

sure it’s stable.

After the second floor reached around 40cm’s

height, tutor suggested us to limit the number of

bricks in each level to reach as tall as we can in the

shortest time. Hence the shape of each level change

from square to circle and become smaller

And finally become to two bricks per level.

The competition with group 1 started as the

time was almost finished. Though we

realized the unstable of this structure ther

was no time for us to restructure it and it

collapsed in the last minutes.

Finall tower:

During the weight capacity test group 1’s tower, I thought it

will collapse at red circle, however it collapsed at purple

circle.

Posible

collapsed

point

During the deconstruction of the tower. We started

from the based columns, then up to the second level:

Then the third level:

Finally, two side of the tower was removes and the

force only carried on the other two. Hence when I

try to move one brick at the circled area, the tower

started to shake and finally fell down.
