WEEK 6 - STUDIO JOURNAL This week groups were told to recreate a structural model of their chosen building with balsa wood, super glue and pins. Our group made a model of the Ormond Theology building, consisting of only the primary structural elements of the building. Because the building was quite large, the plans for the building were very complex and took a while for us to correctly identify the structural elements of it. The model made solely focused on the entrance of the building.
Working with the drawing plans, we decided it was appropriate to work with at a scale of 1:20, which would produce a model of appropriate dimensions. In our design, we demonstrated the interactions of the two sections; how the cantilevered roof relies heavily on the column arrangment to create a balanced centre of gravity and to transfer the roof loads to the ground, whilst the roof stays upright due to its connection with the cantilever. We also chose to display the internal structural elements of the two structures, the beams and the columns.
The structure relies heavily on a columns grid pattern to effectively transfer the loads that the building is subjected to into the ground. The front entrance is held up by four columns with a structural beam midway. The roof is held by beams that connect the columns together and the roof is cantilevered by the balso wood columns on the side of the building. In real life, the roof is cantilevers by external concrete columns. Although it is not shown on the model, the building uses shallow concrete footings, also known as a spread foundation. However, in some areas of the building, it uses a concrete slab foundation.

When putting the beam to the test, it was found that the beam failed when the weight reached 200 kg. Surprisingly, it was the plywood that because although the plywood had the vertical direction, there was little This is why the beam underwent
The design chosen is shown in the sketch above. The two plywood strips give the beam the overall shape and form, while the pine wood is used as bracing and giving the right spacing between the phywood strips throughout the beams. The pine wood was cut into lengths to give the desired spacing and nailed into the plywood. As all the beams were rectangular, they were all placed so that the wood would buckle or yield along the larger axis, which means that the wood could take a larger load before buckling. Because the plywood was very long vertically, it was thought that the plywood would have a large compressive strength.
as seen in the photos above and to the left. Also, because of this twisting, the nails that held the pine wood to the plywood began to pull out. However, the plywood did have a high ductility as a lot of cracking could be heard before the plywood fully failed in the middle of the beam.

One of the other groups made a ladder beam, where the two pine wood beams form the shape of the beam and another pine piece was cut to form the spacing. The plywood to nailed diagonally on the side of the beam as bracing. When the above. After a while, the top and bottom chord of the pine wood cracked and failed. The cracks happened to the left and the right of the middle, which is circled in the photo above.
With this beam, the beam consists of 3 pine wood pieces arranged in an I-section. The plywood was nailed on the side as bracing. When tested, the in the photo above. Interestingly, the plywood in the middle stayed in place as the load was concentrated in the middle, while the ends of the Also, the beam failed when the bottom chord of the beam was completely uprooted from the rest of the beam.
This beam took the most load before failing. This beam was arranged so that two plywood pieces were staked on top of each other along the longer faces of the rectangular beam. Again, the cracked and failed perfectly in the middle of the beam where the load was concentrated.
