Behavior in earthquakes or hurricanes
In case of a dynamic overload, as it occurs in earthquakes and hurricanes, following reactions can be realized: Statistically steel fails before concrete does and if steel failed long ago and 80 percent of the concrete constructions collapsed, then only 10 percent of the constructions of bamboo and wood would fail, see diagram!
Another advantage of bamboo, which is not taken into account in the statistical consideration before, is the absorption of energy in the joints. At excessive load, about 85 percent of the energy is used for the deformation of the joints, and only 15 percent cause elastic bending of the material.
Bamboo keeps helping after the earthquake, too!
As the forests are in peril in Indonesia, the villagers are poor, Giant Bamboo is the answer all the way around. It is the strongest most flexible material for building in a earthquake zone, it can grow more than a metre a day, new shoots can be started by cuttings, it makes a terrific barrier against wind and possibly, wild pigs and tsunamis (like the mangrove forests).
I have contacted Paul Wandera at Bamboo Kenya (click on title link) to see if I can hook him up with IDEP, Howu-Howu, SAI, and Surfzone Relief.
Bali is a major consumer and user of Bamboo, and IDEP is based there. I am hoping we can get some shipments of cured giant bamboo for building started for the villages, as well as the delivery of cuttings so they can start to grow it. Birdie (see below for more from Paul's site)
Bamboo is many things to many people.
It is apparent that the bamboo can play an important role in the development of the country’s economy and especially the rural economy by generating entrepreneurship and employment. The potential has however not been recognized.
WHO WE ARE
Bamboo Kenya was founded by, Paul Wandera an architectural technician and bamboo enthusiast. We are eager to share what we know, to educate and teach people about bamboo. Bamboo Kenya has visions and ambitions for the broadened use of bamboo in Kenya looking for sustainability and visibility. We want to focus our energy solely upon finding a solution to, environmental concerns regarding the diminishing forest resources in Kenya and to inform people about bamboo as an environmentally renewable non-wood forest resource. Apart from this Bamboo Kenya would like to start informative educational programs on bamboo that will protect tropical forests by promoting and demonstrating the many conservation and development opportunities that bamboo offers. We will strive to promote the use of bamboo and educate others about the greatly misunderstood and underutilized benefits of using and preserving this plant. One of the main ways in which we hope to accomplish this is through our educational and our consultant services and by your continued participation and support.
Bamboo is a survivor it bends but it doesn’t break.
