practical shelter innovation for disaster relief

Improving security

Both the steel and bamboo RSKs can easily be made into a more secure shelter by the occupying family.

Two special properties of the reciprocal frame roof make this possible .

1. The weight bearing strength of the roof

2. The reciprocal frame roof does not exert "outward spreading" forces at its points of support like conventional gable roofs.

Sandbag shelter

This enables the roof to support a covering of foliage, wood, branches or reeds.


This enables solid walls to easily be built to support the roof frame. Earth bag walls can be built up gradually over several days.
