Mass reduction for mass appeal: FRPs and CMCs in RVs Whether we’re talking about pop-up campers hitched to passenger cars, “fifth wheels” — large trailers towed by pickup trucks — or self-propelled luxury motor homes (affectionately called mobile apartments), those who manufacture them are keen to take weight out of recreational vehicles (RVs). But unlike passenger car and commercial truck OEMs, those who build RVs aren’t motivated so much by pending fuel economy and/or greenhouse-gas emissions mandates — at least, not in North America, where the regulations don’t apply directly to the RVs themselves. Instead, the impetus for lightweighting has two other rationales. First, every pound/kilogram of mass removed is another pound/kilogram of consumer comfort items (e.g., big-screen televisions) that can be added without necessitating that the RV be pulled by a vehicle with greater towing capacity. After mass reduction, the hot issue is to reduce RV post-sale maintenance. Raising the rafters Building a better mouse trap Alum Bank, Pa.
BUILDING BIG: Dome Challenge Basics They have been called "the kings of all roofs," and they cover some of our most important buildings. Domes are curved structures -- they have no angles and no corners -- and they enclose an enormous amount of space without the help of a single column. Despite their thinness, domes are some of the strongest and stiffest structures in existence today. Before domes, there were rectangular buildings. Soon, ancient engineers began experimenting with arches. The earliest domes were made of stone. In the quest for height, engineers came up with a few tricks. The U.S. But a 20th-century invention would change dome engineering forever. A new generation of domes equipped with retractable roofs, like the Toronto SkyDome, has become a popular choice for sports stadiums throughout the world. Now that you know a bit about the history of domes, test your knowledge in the Dome Challenge!
Maison en sacs de terre de 50m2 pour 8700 € construite à 3 en 8 jours Dans les pays occidentaux, le secteur du bâtiment est énergétivore et fortement émetteur de gaz à effet de serre. De plus, construire une maison engloutie les budgets des ménages. > Le concept de maison en sacs de terre permet d'utiliser des produits locaux (terre trouvée sur place) et à un coût dérisoire. Cette maison, un vrai bunker, est presque indestructible. En secteurs fortement déboisés (Haïti, Afrique subsahélienne etc.) le concept d'EcoDome apporte un avantage majeur : sa construction ne nécessite pas de bois (pas de charpente). De la lune à la terre... - Olivier Nader Khalili est un architecte irano-américain qui a travaillé sur l'architecture lunaire dans les années 80 et a développé des constructions en sacs de sable, qu'il appelle "Super Adobe". - "The real form of poverty is the poverty of hope.

Basalt Rebar (Zeebars) Basalt Rebar (Zeebars) Here’s a natural substitute for steel rebar. It seems like this material would work perfectly with earthbag building, especially in seismic areas where additional reinforcing is typically required. “Zeebars Basalt Rebar is an alternative to steel and fiberglass for reinforcing concrete. Zeebars are naturally resistant to alkali, rust and acids. Allowing thinner, lighter panels and decks, Zeebars reduce the thickness and spacing between the rods and the concrete and surface. Basalt rebar does not conduct electricity or induce fields when exposed to RF energy, great for MRI or data buildings. Smarter Building Systems Neo Geo: geodesic construction in contemporary architecture | Article - Iceweasel The MyZeil centre in Frankfurt by Massimilano Fuksas demonstrates the complexity of form that can be achieved with modern materials and techniques Geodesic construction is founded on the principle that the triangle is an inherently stable form, independent of size, and that a triangular framework held together in tension enables the creation of structures that are lightweight but profoundly strong. Applying these building methods to spherical forms encloses the maximum interior volume with the least amount of surface area, meaning significant material and cost savings can be achieved. These inherent benefits have ensured that geodesic methods remain a relevant and popular choice for architects and developers seeking to 'do more with less'. Cornwall, UK: almost two million people visited the Eden Project's biomes in their first year of opening One of the most successful and popular modern geodesic buildings celebrates its tenth anniversary this month.
Conduit Dome Tips Conduit, or EMT seems to be the material of choice for domes at Burning Man. Conduit is easy to work with, relatively inexpensive, and plated so painting isn't necessary. This page will provide tips for making conduit framed domes. STEP 1: Deciding on a frequency The first thing you need to do is figure out what type of dome you want to build. STEP 2: What Size? STEP 3: Calculating Strut Lengths This is where the Dome Calculator comes in. Step 4: Eliminating Waste This part is tedious, but worth the effort because it will save you money and you won't have to feel bad about throwing away tons of wasted pipe. Step 5: Cutting the struts Cut the tubes according to the strut factors plus 1½". STEP 6: Flattening the ends OK, there are a few ways to do this part. Step 7: Drilling Holes To drill the first hole in each strut, cut a V groove in a 2 X 4 six inches longer than the longest strut. Step 8: Bending the Struts Now the struts need to be bent to the correct angles. Step 10: Break Time!
Basalt Fiber Rebar The construction industry is becoming aware of the existence of reinforcing bars made from fiber-reinforced plastic. Fiberglass rebar has been on the market for some time, making inroads where steel rebar doesn’t work well. The first common applications have been used in corrosive environments and places where the induced fields resulting from steel reinforced concrete structures exposed to high levels of radio frequency radiations are a problem. Basalt is a common volcanic rock, found throughout the world where volcanoes have erupted and sent lava to the surface. This one structure could sustain a vast basalt filament industry for many decades. Basalt rock is quarried now for many uses, including use as road base. The basalt usually exists as thick slabs corresponding to the depth of the original lava flows, and fractured vertically through the flow. Before a basalt reinforced rebar can be made, one must first produce basalt continuous filaments. Several things need to be noted here.
