practical shelter innovation for disaster relief
This workshop is the first to investigate the use of a new construction concept, the reciprocal frame, for building bamboo relief shelters. For countries with bamboo resources it offers a completely new option for supporting tarpaulins.
The key findings and recommendations are summarised here but it is hoped the full report will be of interest to everyone in the shelter relief sector.
A joint project with Bikalpa at IMBS college, Chakaput, Kathmandu, Nepal from 30th April to 3rd May 2013.
Green bamboo
Fresh cut bamboo was suitable for all 5 types of
shelters built. Potential weaknesses were
highlighted and solutions identified.
Dry bamboo
Particularly suitable for larger span shelters; a
new type of double elevated ReciproBoo shelter
was built.
Ease of construction
Bamboo reciprocal frame roof shelters are
quickly erected using only basic cross-lashing
skills.
Strength of shelters
The strength and exceptional span of reciprocal
frame roofs was well demonstrated .
Other advantages
Simple shelter kits that can be upgraded to
more permanent shelters. Cooler and better
ventilated.
Adaptable to any terrain, especially urban.
Cost
The 7 pole emergency shelter frame kit cost
retail US$10 ( 877NPR) and the large 15 pole
double elevated shelter US $17.70 (1.560 NPR)
Specification data
Specifications from 7 pole basic to 15 pole
double elevated shelter kits, determined and
recorded.
Bamboo is very suitable for this type of shelter construction due to its rigidity and high tensile strength.
The shelters constructed offer substantial advantages over conventional shelters while using 33% less bamboo.
Recommendations
Disaster preparedness
Work with local government and Aid Agencies to see how these types of shelter kit can improve disaster preparedness.
Consider using this highly adaptable shelter in the difficult terrain of urban disasters.
Pilot scheme
As for funding obtained in South Sudan to test large scale field deployment of shelters.
Stockpiling of shelter kits
Consider stockpiling shelter kits that can be rapidly mobilised when needed. This highly adaptable shelter has particular advantages in urban disaster situations.Alternatively a resource of prepared dry bamboo for construction would be invaluable.
Further work.
A joint workshop with ReciproBoo, Bikalpa and Nepal Aid Agencies to compare strengths of RSK with traditional structures and complete the work as outlined in the report.
