An arch truss pasta or spaghetti bridge (Bucatini and Fettuccine) is made in this video. The bridge weighs about 950 grams or 2.1 pounds and took a load of 19 kg or 41.8 pounds before failing. If abutments were provided to restrain the arch ends, the load capacity would have been more! This can be a cool bridge for a Science project.

@burkean 4 года назад

Some things I like about your construction technique: full-size scale drawing for measuring lengths, quick way to cut several pieces to the same size overlapping spaghetti for the tensile members Design features I'd change: End members in unsupported bending tensile members are thicker than necessary. If the bridge deck spaghetti had been lengthwise instead crosswise, it would have added strength

@StructurePlanet 4 года назад

Thanks for the detailed analysis. You are right about the deck orientation and as you mentioned there is room for improvements.

@yes-ji7eg 5 лет назад

Hi! What makes your bridge strong and why? Why did you make an arch bridge instead of a truss bridge?

@StructurePlanet 5 лет назад

When testing a craft stick or spaghetti bridge, the first member failure usually happens in the top compression chord (buckling failure). However, arch bridges are naturally stronger in compression due to their arch action. So for a spaghetti type material which is very weak in compression, arch bridges are usually a better choice :)

@yes-ji7eg 5 лет назад

@@StructurePlanet Thank you so much for replying! I have a spaghetti bridge project that I have to make and give on Next Friday, and we have to make a spaghetti bridge but it has to be out of scotch tape. I have a few questions, how do you find the center of gravity in a bridge and the magnitude of the bridge?

@StructurePlanet 5 лет назад

Center of gravity is the average location of the weight distribution of a structure. In a symmetrical bridge, I would think it will be the center of the bridge. Basically, It is the point that you can hold and balance your structure with one finger without it falling. Well, there are many factors affecting sizing for a craft bridge. It mainly depends on span length and how much load it should take. I usually size the craft bridge to have a span over depth ratio of 4 to 7.

@Bushcraft-xz6xd 3 года назад

Bridges are anchored each end not just placed on the ground. I saw the ends slip outwards under load which would not happen if the ends were glued like real bridges are and would have made it stronger and not fail where it started to?

@StructurePlanet 3 года назад

You are right. Arch bridges need supports that are capable of restraining the end movements.

@pedraza6615 Год назад

Did the arches get wider from top to bottom

@witchingmushroom1761 4 года назад

It was not necessary to make the horizontal part of the bridge a separate part in the place of the support. Then the force would be distributed evenly, and the beam would be loaded by bending, and not by compression. But Nevertheless, everything turned out pretty cool! !! !))) Good job!

@StructurePlanet 4 года назад

Thanks for the comment. Yes. If I had the chance to redo this, I would have done few revisions to the end supports.

@khalidmohammed1980 4 года назад

how can I make a stronger bridge I think if we make a bridge looks like the opposite shape of bending moment diagram PL/4 it will be stronger than the arch shape do you agree ?

@StructurePlanet 4 года назад

I don't think so. I think if you connect the arch ends together using 10 or 20 spaghetti strands, it will take much more load. Alternatively, you can use half a circle shape which will be stronger too.

@StructurePlanet 5 лет назад

Hi Mayar. Are you asking about the sectional area of spaghetti bridge members?

@mayarhamddy5954 5 лет назад

Yes

@StructurePlanet 5 лет назад

Each strand's sectional area is about 6 mm2 (rough estimate). You will need to multiply this by the number of strands used for each member.

@juliaeliasson817 5 лет назад

Why did it broke? How to make it even better

@StructurePlanet 5 лет назад

You can improve the capacity by doing one of these: 1. Arches require abutments (buttresses) at both ends so arch can bear on it and to limit the movement of the arch. This will result in a higher capacity automatically. 2. One other way to do this is to connect the two arch ends together with some spaghetti strands or fishing rope. 3. Or to make a half circle arch instead to avoid having horizontal reactions at the base from arches.

What are abutments?

@StructurePlanet 5 лет назад

Abutments or buttresses are stiff structures at the ends of bridges to carry the bridge superstructure vertical and horizontal loads to the foundation. For a craft bridge, it can be a simple wood section nailed to the table or a heavy concrete block placed at the ends of the bridge.

:( Haha. A much better ratio can be achieved with this design if: 1. Reduce the weight by not adding the noncontributing parts such as the deck and extensions. 2. Add lateral supports for arches during the load testing or connect each arch ends together with pasta. :)
