| Analysis of Building Damage in Tibeten Area Cased by Sikkim MS 6.8 Earthquake of India |
| Abstract： On September 18, 2011, a MS 6.8 earthquake stroke Sikkim, India, which also had a great impact on its adjacent area in Tibet of China. After conducting field investigation on building damage and economic loss, we analyzed the problems that are related to anti seismic issue, and proposed some suggestions for the earthquake resistance consideration in future. The basic principles of seismic design for buildings in Tibet then was put forward and concept design of residence anti-seismic was emphasized. Through anti-seismic measures and principles, we can greatly improve the seismic resistance of houses, reduce earthquake casualties and losses, and promote the harmonious development of the Tibet with a reasonable increase of the construction budget for earthquake safety countermeasure. |
