We all know how the very recent massive earthquake in Japan claimed many lives. From all such incidents across the world, it was observed that some deaths are happening due to building collapses. Taking this in to account the Environment Ministry of India identified some regions in India which require quake-proof housing.
For all such earthquake-prone areas, the Ministry recommended the new style of quake-proof houses made with bamboo, which have been developed and successfully tested by Bangalore-based Indian Plywood Industries Research and Training Institute (IPIRTI).
The ministry in its annual report mentioned that the bamboo houses built by the institute based on IPIRTI-TRADA (Timber Research and Development Association) technology, can resist seven repetitions of a typical ‘Zone 5 earthquake’, the highest in India, which is equivalent to over 7 on the Richter Scale. It was also told that the bamboo houses showed no signs of falling apart, in contrast to a concrete structure, and have only a few cracks that too at the end of the most intensive of shocks.
The scientists from IPIRTI tested the bamboo house by mounting it on a ‘shock table’ and delivering a series of base shocks through a simple pendulum device, whose impact was comparable to earthquakes. The houses which they tested have bamboo grid and wire mesh, plastered with cement mortar for walls with bamboo columns providing support. The ceiling is made of light bamboo mat corrugated sheets developed by IPIRTI.
