“EARTHQUAKE-PROOF BUILDING”
Structural Analysis Questions:
A. During construction, how did you test the strength and stability of your structure?
-We tested the strength and stability of our structure through constantly checking the parts of the building while making it. After finishing the first story, we tried to put pressure on it to make sure it was firm enough to handle weights. The same goes after finishing the second story. For finishing touches, we added more straws as stands to surely support the building. We tried putting weights more than 250 grams and even placed a laptop on top of the building. It did not collapse nor got damaged, by then we felt confident with our building.
B. During construction, what strategies did you use to strengthen the weaker areas? Why?
-In my own opinion, I did not trust the use of paper clips inserted inside the straw to connect it with each other. What we did is that we drilled holes on both sides of the straw and inserted a straightened paper clip and tied it together. Also, to strengthen the weaker areas is that we added more straws for support, tightened it with more paperclips, and even added pins on some edges of the building.
C. What are the strongest parts of your building? Why?
-The strongest part of our building are the four corners because the straws that stood for support was mostly connected to it. Also, all sides were very firm because of the support. Over all, most of the building’s parts were very strong.
D. What are the weakest parts of your building? Why?
-The weakest part of our building was the center part of the second story because there was no straw placed in the middle for support. I didn’t place a straw there because it would hinder the sandbag to be placed properly on the platform of the first story. Also, I think the width of our building was too small that the sandbag would easily fall from it.
E. Where did you use string in your structure? Why?
-We used the string to connect all four corners of the middle level of the building to the cardboard base. This was because I believe that when the testing day comes and our building would sway rapidly, the strings would hold the building to its base and avoid collapsing.
F. Where did you use pins in your structure? Why?
-We used the pins to pin intersected straws because I believe this would avoid displacement of the straws.
G. If you had 5 more straws, where would you add them? Why?
-If we had five more straws, we would not need to use them anymore because our straws were more than enough. If so, we could use five more straws for decoration.
PS --> I broke my nails because of this project huhuhuhu it isn’t as feminise long nails as it was before. lol XD
