Joining seminars about using organic vegetables and fruits is really a great oppurtunity for us students. We also get the chance to meet different people with different fields of expertise and skills. Lets all go for organic farming because its not all about helping the farmers but also the environment.

Earthquake Proof Building

STRUCTURAL ANALYSIS QUESTIONS:

A. We test our building by putting something heavy like cellphones and we even try shoes to make sure that it is already good to go.

B. Yes, we strengthen the weaker are because we want to make sure that it wont collapse. We look at every possible weak areas so that it will be consistently built.

C. The lower part or the ground floor where we put more straws, because we want that our building will not be moved in an constant motion so that we can avoid to collapse and we make sure that it is strong atleast if the upper floor will dance the lower part is not more affected with the earthquake.

D. The upper most part, because of the straws we lack straws to be used because we put more straws below.

E. We use string in the second floor where the object will be put on, because we want that the object will not fall and it will support on the straw that we put in there.

F. We put strings everywhere that there is needed just to fully support and strengthen our building.

G. We’ll put it on the most upper part because it is the weakest part of our building.

STRAW BUILDING CONSTRUCTION A. During construction, how did you test the strength and stability of your structure? We made sure that the straws that are fastened are tight enough for it to avoid any twisting motions. After this, we made sure that our first floor is strong enough to carry the entire burden. By doing this, we placed 300g and more and we started shaking our first floor so that we can estimate its strength and stability. B. During construction, what strategies did you use to strengthen the weaker areas? Why? It was late when we realized that we could use paper clips instead of pins to attach the building to the base and the other weak areas. We sharpened the tip of the paper clip so that it will be easier to get through the straw and looped it around. C. What are the strongest parts of your building? Why? For me, the strongest parts will be everything in the first floor because we tested it and it can support a lot of weight. We made sure that the foundation of the first floor should be the strongest so that it can carry the rice bags. D. What are the weakest parts of your building? Why? The weakest parts will be the parts in the second floor because it is not directly attached to the base. E. Where did you use string in your structure? Why? We used it to knot almost everything on the first floor because for us it is ideal for knotting and it is easier than using paper clips. F. Where did you use pins in your structure? Why? We used the pins to connect the diagonal support of our building so that we can avoid it from slipping away. Also, we placed it in our base because we don’t really need it that much. G. If you had 5 more straws, where would you add them? Why? I will use the two straws in our first floor as a diagonal support so that the first floor will be strong. The 3 remaining straws will be added to our second floor so that it can support the weight that will be placed on this floor.

Earthquake proof building

Honestly, after I heard the announcement that we are tasked to build an earthquake proof building, I feel so stress already. I don’t have any idea or any tactics to apply in making that building. Few days passed, I feel so worried already.

During construction, how did you test the strength and stability of your structure?

We made 3 structures all in all. We test the strength and stability of our building by putting 2-3 cellphones on the first and second storey and afterwards we will shake the building.  The first structure, the straw was too weak for our building to withstand the intensity of the earthquake. The second structure, there were too many straws being used. And the last one, we decided to plan first for how many straw we will use and we will make it lesser hassle. We decided to use more paper clips than pins since the limit of number of paper clips, which is 100, is just enough for our building. And paper clips are lesser hassle to use than pins.

During construction, what strategies did you use to strengthen the weaker areas? Why?

There are a lot of strategies to make the building stronger. But we chose those tactics that will use lesser amount of materials in order not to maximize the required materials. One of the strategies would be the two straws that are bent outside of each corner of the first storey and as well as the strings, to support the building from standing straight and it will cause lesser shaky. We also used stronger straws compared to our first structure.

What are the strongest parts of your building? Why?

My answer would be the first storey, since there are lots of supporters attached to it to prevent it from shaking and breaking down.

What are the weakest parts of your building? Why?

The second floor, because we used too much straws in supporting the first floor that we forgot we still have to make the second floor. And the supports in first floor are stronger than the second floor. That’s the reason also why we are having a hard time finishing our building because we got stuck up at the last floor.

Where did you use the string in your structure? Why?

At first, we have no plans using the string because we thought it’s not useful. But our classmate told us to use string to make our building more stabilize. That’s why we use it by tying it to our building and to our base so that it won’t fall down.

Where did you use pins in your structure? Why?

Back to our first structure, we use pins everywhere! I mean literally. But then we realized pins are too hassle to use. And we there should be 20 pins only to use. That’s why we plan to use the pins at the second floor, to bond the straws that are used as a stabilizer of the second storey.

If you had 5 more straws, where would you add them? Why?

If given a chance to use 5 more straws, we would probably put it on the second floor and use it as a stabilizer. Because honestly, our second floor is too weak to withstand the major earthquake.

To sum it all up, making that kind of building was never easy! And you really need to plan the strongest structure ever so that it can survive for any kind of earthquake as well as any amount of weight!
