Last December’ s earthquakes in the Iranian city of Bam took a huge death toll—roughly 40,000 people—largely because of the collapse of thousands of mud-brick buildings. If a group of researchers in India are successful, the earthquake might not be as destructive. British and Indian engineers are developing earthquake-proof housing using a cheap, universal material: bamboo.
They designed a model house built around waterproof bamboo-sheet roofing and bamboo-reinforced concrete walls. To test the structure, the engineers, sponsored by the U. K. Department of International Development, took it to the Earthquake Engineering and Vibration Research Centre in Bangalore, which has a state-of-the-art earthquake simulator(模拟装置). The researchers shook the house with five house with five successive 30-second pulses, being equal to 7. 8 on the Richter(里氏)scale. The simulation was more than 10 times as violent as the Bam earthquake, yet the house emerged undamaged. "We didn’t even crack the paint," says engineer Paul Follett, of Britain’s Timber Research and Development Association.
By some estimates, more than a billion people already live in bamboo structures. The innovation lies in developing ways to exploit bamboo’ s spring. Easily pre-built, fire resistant, and far lighter than steel, bamboo-based structures could be assembled in three weeks and last 50 years. At five dollars a square foot, they would last roughly half as much as brick-and-block constructions. Follett says the project will follow an " open source" model: " Whatever is developed is freely available for the common good. "
The researchers have been working hard to______.
选项
A、reduce the damage by earthquakes
B、explore the functions of bamboo
C、build bamboo houses for a billion people
