Very strong and lightweight structures can be built using bamboos best property tensile strength with splits. But by treating bamboo, it is possible to make it last decades!Methods for treating bamboo include heat treatment, pressure treating, soaking, or through vertical soak diffusion with a borax/boric acid mix. Bamboo joint with metal anchor. I only use these when strength is of utmost necessity. Any suggestions as to how to join these at the top would be greatly appreciated. It can also be cut into thin strips, flattened, then boiled and dried to create laminated sheets and planks, one form that is currently seeing a huge surge in popularity, not only in China and Japan (which have honed this method throughout history), but also in the Western world. Start adding them to your collection now so that you have them ready when it comes time to build. The two pieces are fit together and then bamboo pegs are used to secure it.

Dendrocalamus Asper splits are used for structural elements and Gigantochloa Apus for non-structural elements. Sign up with your email address to receive news and updates. Instead use nylon, steel or vegetal cord of the appropriate diameter. The worlds best bamboo eco- architecture courses for creatives, designers and architects passionate about bamboo construction and sustainable design. I saw some info about creating strong bamboo joints when using Guadua in building construction, especially adding cement to the joints. Joint with dowels and clamping fitters. TransProfessionals est une compagnie ne en Grande-Bretagne et maintenant installe au Benin. Essentially you are adding a piece of bamboo at a 45 degree angle between a horizontal and vertical piece of bamboo. The starchy material that attracts insects within bamboo can also be removed to reduce infestations or it can be treated by heating in a kiln or over a smoking fire. The pool hang-out pods at the Bamboo U campus is one of the best examples of how to build beautiful woven bamboo structures using splits. Bamboo is a great material to use in construction and after learning a few basic techniques, it can be really easy to build with as well. However, it requires specific techniques to achieve extensive curvilinear forms. But with the right tools you can make building with bamboo go a lot faster.Below is a list of my favorite tools to use when building with bamboo. Some varieties of bamboo are great for structural poles, others would be better used as wall material.
2. Bi weekly guides and content created for the aspiring bamboo designer, architect and creative in mind. The first and most important step of any construction project is to give it a set of good boots, or a strong foundation. The peg should be placed in the column parallel to the rafter. The disadvantage of this jointing technique is the reduction of the strength of the bamboo because of the cutting of the hole. 3. 
They are the predominant way to join two pieces of bamboo together and secure them down. The Induo-Anchor technique is used for bamboos with larger diameters. The recent surge in popularity of bamboo construction is a promising sign for sustainable building and the experimentation with the growth of bamboo outside of its traditional distribution (including a project being conducted in the Mississippi Delta) could only enhance this. Related: How To Propagate Bamboo, By Cutting, Airlayering, and Division. 
Most people will claim that bamboo doesnt last long, which is true if your bamboo isnt treated. The wall, floor, and roof elements are interconnected and depend on each other for stability. The nipa hut in the Philippines is one example of a basic bamboo housing structure, with bamboo poles used to support the structure and the walls composed of split and woven bamboo, while in China theres evidence of bamboo-built bridges having stood since at least the 10th century. The result is a curved and flexible element that is adjustable in shape, dimension, and length.
The strength of bamboo largely comes from its integral structure, which means that it cannot be joined used many of the techniques we have traditionally come to know in building using wood. We thread the bamboo culms into the nodes using conical end bolts. Its not only a green solution for the developed world, but a low-cost, readily-available resource in many regions of the developing world where modern building materials are scarce and expensive. During thedrying processthe bamboo diameter shrinks, so when bamboo is used in joinery this will result in lose and weak joints after a few weeks.
Bamboo columns or beams need to have a node atboth ends(or as close as possible towards the ends), if not the pressure of a structure on the joint may crush the bamboo. Shaping and curving whole, hollow bamboo poles in their natural form is challenging because of their cylindrical profile but it can be done using the rup-rup technique. When you join you get additional benefits. Log in to TheConstructor to ask questions, answer peoples questions, write articles & connect with other people.

An untreated bamboo culm has a brief life span and is prone to rot and insect attack. Only if the problem with bamboo joinery can be satisfactorily addressed, andsimplified, we can expect to see much more bamboo in Western buildings, bridges and furniture. Bamboo is susceptible to the detrimental impacts of not only insects, but also rot, fungi and fire, so it does need to be treated both inside and out. If not the bamboo will splinter when struck (for example to position the column).

This connection increases the speed of construction by eliminating the time required for the fabrication of dowels. Because photosynthesis is at its peak in the middle of the day and high sugar levels are produced in the sap, many believe that dawn or dusk on a waning moon is the ideal time.
2. Lashings, wraps, fraps, and clove-hitch are some knots used in these connections. They dont require fertilizers or pesticides for growth, and their extensive root system helps to draw in and store water, reducing the impacts of soil erosion. The outer surface of the bamboo lacks grip and is very slippery, making connections difficult. With the ever increasing prices of lumber and the immense environmental damage that clear cutting has on an environment, hopefully bamboo will find a way to make it as a building material of the future. A bamboo culm has a round profile which makes the, complicated.
The properties of lidi bundles allow us to bend in 3 dimensions - double curvature.

However, when there is a heavier or structural load on a joint or where two pieces of bamboo comes together, a bolt with appropriate sized nuts would be a stronger alternative. Door, windows, rain gutters, pipes, roof coverings are some non-structural applications of bamboo. Positive fitting connections are widely used in traditional bamboo construction. It is important to keep all these constraints in mind when designing a bamboo joint. Most trees can only be harvested every 25-50 years, while bamboo can be harvested every 3-6 years, depending on the species. To get tighter connections, we use green bamboo strips. The new Green School Bali gym designed by IBUKU is the largest arched structure in bamboo of its kind in the world and is composed of 18 arches, which are built on the ground using the rup-rup technique.
