If you need a clue…Find the centre of a pentagon and count how many struts there are to the centre of any other pentagon. OK now that you know a little about dome frequency take a look at the dome below and work out what frequency it is. Basically the v in 3v stands for frequency. The greek letter for Phase or frequency is Nu or Nv written N in latin the lowercase (ν) is used as the symbol for spatial frequency of a wave in physics and other fields, a measure of how often components of a structure repeat per unit of distance. This is why 3v domes don’t have a flat base and come in 4/9th or 5/9th versions. Notice how only even frequencies have a dividing line exactly across the centre of a sphere, while odd frequency spheres have to be divided slightly above or below the centre line. Higher frequency domes just have more subdivisions the diagram below shows how 1v, 2v, 3v, and 4v spheres are subdivided. To increase the frequency we have to do two things, first subdivide a face into more triangles then project out the vertex of each triangle to an imaginary sphere encompassing the dome. All frequency domes can be traced back to this basic form, which can be classed as a 1v geodesic sphere. If you look at the example you will notice that all the struts are the same length and all the triangles are the same size, quite a beautifully simple start point for building a dome. Icosahedrons have 20 equilateral triangle faces that form very roughly a sphere. We will start with an icosahedron, as most geodesic domes are based on this basic form. Many people get confused about geodesic dome frequency this article will explain what geodesic frequency is and show you a simple method to discover what frequency any dome is just by looking at it.
(and more)Īnd the writer introduce the Geodesic dome frequency: Geodesic dome frequency explained (This is another people who did Geo Dome work, really amazing and can learn some knowledge from them.)Īccording to my research, The kinds of Geo dome at least have 1v, 2v, 3v, 4v, 5v, and 6v. Leave a comment Researching about Geodesic Dome - Geodesic Dome frequency Researching by Pleasant Wall Team on August 20th Which is this one, and there are some idea which we abandon: We decide to use the Mab flat Bracket carinya to be our connector.And this is my sketching about more connectors:.but why we don`t choose the other connectors which have good prize, right?Īnd there some common and useful connectors: The “Star connectors” are really popular and famous in the area, most people choose it but its too expensive and also hard to get or find people to make it for us.Therefore I do some research which about the connectors. Today`s researching is about the connectors of the Dome`s construction, Connectors are really important part of the geodesic dome.
Her plan gave us a totally and good view which happened in my mind which about the structure of the dome. Because the manpower and material resources is limited. * Water test was scheduled on the next coming day.įrom Capri`s work which by Revit and our researching, we knew the dome design should be small but delicate. ↓↓↓ We have done it!!! The physical model is now basically completed and all we need was an opening. Roof fixing, to avoid water leaking in the center, strength the water proof functionality. But after trying different methods of cutting, we gradually figured it out. It was not an easy work in the process as the dome is a semi-sphere and it was hard to make the plastic film to fit the form of the model. If we did not find it, the model would not be an 3V dome and it would result as a total failure.įinally, we were doing the last part of our structure. Yesterday we made a mistake about the dome`s structure by placing a few grid wires at the wrong points where they were not corresponding to the opposite. We were still at the stage of building the structure of the dome. Second day, we were moving to Capri`s apartment to continue our wall project.
