Affordable Earthquake Resistant Houses
This year we witnessed the extraordinary dangers of mixing buildings with earthquakes, especially in poor areas – fortunately, the group called PAKSBAB is to find a solution.
Pakistan Building Straw Bale and appropriate nonprofit that works to develop durable buildings which can be built with local resources, little money and stay safe during a violent earthquake as 7.5 on the Kashmir earthquake in 2005. The main ingredients are hand-made straw.
PAKSBAB’s founder, Darcey Donovan PE, left for Northern Pakistan to provide assistance in rebuilding the devastated region. He brings his extensive experience with straw bale building. When he found that there was no binding machine where housing is needed, so he developed a simple jack system and form needed to produce hay. The prestress bails set above a stone foundation and supporting the roof truss. Bamboo and help secure the mesh wall.
Pakistan Straw Bale Building and precise (PAKSBAB) is a nonprofit organization created in response to the earthquake which devastated northern Pakistan in October 2005 Kashmir.
Our mission is to adapt, apply and transfer the bales of hay and other buildings appropriate method to protect and improve the lives of the poor, especially in areas of earthquake and extreme weather in the developing world.
Straw bale construction uses straw, an agricultural byproduct, compressed and tied into bales, as a building block. Currently practiced in many developed countries, it offers many benefits, including energy efficiency, use of materials non-toxic nature and resistance to earthquakes, fires and pests.
However, similar to the modern buildings of conventional methods, usually require the use of large energy-intensive and high cost materials, skilled, and complex tools and machines, so most unaffordable for the poor.
In response, PAKSBAB has developed a simple, unique, low cost system the use of renewable indigenous materials, local labor, and adjust the traditional building techniques. our house up to 80% more energy efficient approximately 50% of the cost of conventional earthquake-resistant construction.
The bails act as supporters and wall insulation. Several coats of clay plaster to protect and help preserve hay. 25 ft. 25 ft. The building cost is only $ 2,250 for materials – what many of us are willing to pay for countertops. Currently they have completed 11 building energy efficient, safe, and very low impact.
PAKSBAB recently completed a successful study of seismic shaking table project at the University of Nevada, Reno, with the support of the Network for Earthquake Engineering Simulation and Earthquake Engineering Research Institute. The house survived 8 levels increase in seismic shaking and the acceleration of 0.82g end without collapsing.
How did they fare in an earthquake? To find Ms. Donovan build 11 ft. 11 ft. straw bale structures on the seismic simulation table and let ‘er vibrate. This video shows it in action. Although badly damaged, the building does not appear in danger of collapse, even at the end of the test sequence.
This means saved lives and resources are used wisely by using appropriate building technologies for those who can most benefit. Add items to the list of positive values of straw bale building.
