The traditional wood frame ikra construction of assam and houses of nicobars founded on wooden piles separated from ground have performed very well during earthquakes. Unlike steel or concrete structures earthquake damage to wood frame buildings cannot be readily observed by naked eyes since wooden structures are commonly covered. While you can treat wooden buildings like conventional homes you get better results when you focus on the material in use. The difference in movement between the bottom and top of buildings exerts extreme stress causing the supporting frame to rupture and the entire structure to collapse.

As can be appreciated from the previous discussion of factors that affect the seismic performance of buildings the process is a complex one and difficult to analyze especially for wood frame construction since a large number of diverse components are involved. Inherent flexibility wood s ability to withstand high loads for short periods of time and retain its elasticity and ultimate strength can be an asset in seismic and high wind zones. Wood frame buildings can be designed to stand up to high winds and earthquakes given these characteristics. Wood differs from other materials and you must account for this in your preparations.
