I will ansver the best I can ;

1. My country gets exposed to cyclones every year. As my place of interest is fishermen village beside the sea, I have to build a cyclone resistant structure. Can your structure withstand gusty wind of over 300 miles per hour?

The structures is mainly a framework where each bilding frame is supported by all others, -- now this can be a solution aswell as a problem all depending on the scale of the framework, type of materials and foundations. But being a framework structure, what you could be left with after a gale, could be just this framework without any surface paneling. 300 miles sound as conditions nothing but a heavy concrete bunker would restand, but what destroy light buildings under those condisions , is rather the surfaces and the multible impac the wind and debrie will caurse. Now this is just my view and reality could prove things to be different, but when a structure is stripped for paneling you could emagine that an open framework would restand quite some wind ------- the turbulense created by several frames could protect the rest of the structure, and the form of the structure could help a structure to survive, but if a roof from another building crash into it, there is no way even to calculate the impac.

2. Can your stucture be 2 storied?

Easily as you se in the Manzard renderings there already is pointed to this option, ------ acturly this was one of the idears with this model, to show how floors "grow" and one other thing that is a bit difficult to se from the renderings unless you look very close, is how walls form a row like this ; XXXXXXXXX and in particular a collum form a from top seen single X shape where two sections share the common volume of the original Solids. ----------- I know this is a difficult issue about to se when you first check this method, but when you se it you seen the "magic" you know why it is, that an assembled framework structure is so fundamentaly different from the tradisional methods. Anyway this mean that you have a flexibility in design, that no other method offer, and you can not even compare this option ; please consider this and look for this "magic", it show in a few of the renderings, but please know, that I have carefully made it so, that this issue shuld not confuse so not all models show this feature. ---- please check the structure of the floors under and above, they are simular and then think about how a floor or a roof can just "grow".

3. What exactly are these structural members? Are these wood, plastic, or are these steel?

Sheet material, that be steel, plywood, cast concrete but what you must realise, is that with this method ,you cut "2D" sheet material and without bending one single piece, it will form a framework any shape ------- you don't bend the pieces in a puzzle either as then they don't fit.

4. What is the highest span of making this structure cost effective?

All depending of sheet material type, --- but the important issue, is how each frame is supported by all others, and how some frames reach within and around the building framework, ------- please try to "follow" one of the assembly frames, you will be surprised how one frame , can be part of the floor and continue up the roof or even form part of a wall all in one frame. Now this ask a few small details in the assembly process, so you can make what can be seen as the old steel ring trick, but this is easily solved, and if you check a few more graphics, you se how this is even develobed as a smart side effect, that solve the problem with limited workspace arear on a water or laser cutter ; a way to build in a standard lock, so you can continue long frames. -------- so the best ansver is, that the span is decided by the scale of the framework, the design and the type of sheet materials.

5. Can we extend this structure transversely instead of longitudinally?

Anyway you want, you can, ------- but this is among the things I plan to publish, make different structures in their own direction , support eachother . Guess a few of the 3D-H fan's know how this "limitation" work, and that there are several way't to reenforce a 3D-H structure, but this is no different than the trouble with tradisional structures, except when you solved the most obvious weak point with a 3D-H, you gained a strength you would not emagine.

Now I tried the best I can to ansver, but I know this leave atleast the double amount of new questions ; I can asure you, that this is a very flexible method, but you must look very closely to the local materals and in particular what you can envision as "sheet materials" , also the option to produce a standard framework from a number of standard small frame parts is an option that would be obvious, but this still leave the question, if you in this project build strong , part strong to be able to restore over a strong framework, or if you trust that for each gale you must use the potential in this method to build cheap .
Still there are a very important issue about all this, ----- the method is 100 pct. Digital, and the method will in that way offer the Digital options and new Digital tools ; 3D-H is proberly one of the methods best suieted for a Digital future as it force you to envision a building structure in a compleatly different way ; it offer you a complete freedom in terms of creativity but ask of you to open your mind, and forget about the tradisional methods and the tradisional materials unless you can transform these into 2D sheet materials.
So if you want true Digital options, 3D-H is nothing else than this, also it can show to be the cheapest and easiest way to establish buildings, but please consider that untill now, the tradisional methods had centuries to develob, where 3D-H is only been develobed by one individual with a Vision about a true Digital Direct link to production. As I said just another positive side effect ; like the many ones you will se when you hands-on develob the method.

Anyway please check the search I place in the Link, ---- there are about 12 different 3D-H groups just on Yahoo, and what I could ask you, is to check a few of the Fotos folders in those that is public.
With the other groups you just aply for membership and this is almost automaticly given, ------- but check the Foto's folders in these groups and the graphics I placed in this scrapbook.

Have a nice day.
