Case Study Of Bamboo And Rattan
3.1 CASE STUDIES IN BHUTAN
3.1.1 Tingtibi Community Chief- Bamboo construction
Bhutan joined INBAR in 2009. This is INBAR’s first project in the Kingdom. Bhutan is committed to maintaining forest cover of over 60% at all times, but is facing increasingly severe shortages of construction timber as its population grows and begins to urbanize. INBAR is an intergovernmental organization dedicated to improving the livelihoods of the poor producers and users of bamboo and rattan, within the context.
INBAR’s latest construction project in Bhutan provides an excellent example of how INBAR supports the transfer and adaptation of bamboo construction technologies to meet local needs. …show more content…
Design concept; replacing timber with bamboo as structural element and preserving the traditional architectural form. In Bhutan, bamboo is traditionally used as an infill material for timber-framed house. However, as the cost of timber is going up and supply is limited, people are switching over to concrete, thereby abandoning a rich architectural tradition. This building is built not only for earthquake resistant structure but to preserve and promote the traditional architectural form.
Bamboos are well known for their lightweight, flexible, strong poles that enhance the earthquake resistance of the buildings they are used to construct.The size of the final bamboo structure is 100m2, which at a cost of approximately US$140/m2 is roughly half the price of an equivalent local timber building. For the construction, all bamboo was treated using a Modified Boucherie System, which impregnated boron compound into the bamboo as a prophylactic against pests. Modified Boucherie System offers a fairly simple but effective preservation …show more content…
The house suffered no damage during Sikkim earthquake, thus demonstrating bamboo's earthquake-resistance properties. http://www.indiaenvironmentportal.org.in/files/file/energy%20efficiency%20study%20in%20building%20sector.pdf
The house is built to last, with an expected life-span of at least 20 years, and its earthquake resistance has already been proven — immediately after completion in September 2011 the house withstood shocks from an earthquake in nearby Sikkim, India, without suffering any damage.
