| Summary: | Construction technology continues to grow as it is driven by other <br />
<br />
<br />
technological advances. One of the new things is origami techniques that are <br />
<br />
<br />
beginning to be used in the construction field. Origami is actually an art of paper <br />
<br />
<br />
folding. Today, the word origami is not just about the art of paper folding that is <br />
<br />
<br />
related to Japanese culture, but all the art forms of paper folding from different <br />
<br />
<br />
places are also called origami. <br />
<br />
<br />
With new mathematical and technological approaches, origami can be <br />
<br />
<br />
applied in other fields. Examples of origami applications exist in various fields, <br />
<br />
<br />
ranging from astronautics, health, to infrastructure. The use of the Finite Element <br />
<br />
<br />
Method also makes the structure created with the origami concept can be analyzed <br />
<br />
<br />
before and after the folding process. <br />
<br />
<br />
In this final project, an analysis of lightweight structures made with zippercoupled <br />
<br />
<br />
tube system, a system developed from rigid origami pattern, are done. The <br />
<br />
<br />
finite element method analysis is performed in PATRAN software, with distributed <br />
<br />
<br />
loads on the top of it. The stresses and deflections are examined. Experiments were <br />
<br />
<br />
also carried out on specimens made from paperboard materials, with a couple of <br />
<br />
<br />
masses on top of it, and the deflection is examined and compared it with the finite <br />
<br />
<br />
element analysis. <br />
<br />
<br />
Based on the test results, the specimen is capable of holding the load up to <br />
<br />
<br />
178 times the weight of the structure, with a maximum deflection of 0.4 mm. There <br />
<br />
<br />
is a 10 % difference between test results and finite element modeling. Variations of <br />
<br />
<br />
parameters on the Miura pattern show that the larger the angle of Miura, the <br />
<br />
<br />
greater the deflection but the stresses received is smaller. This is because the varied <br />
<br />
<br />
parameters affect the overall shape of the structure and it affects the overall <br />
<br />
<br />
stiffness of the structure. |
