EARTH QUAKE RESISTANT STRUCTURES

ABSTRACT
Earthquake is the shaking of the ground caused by the sudden breaking and shifting of large sections of Earth 's rocky outer shell. Earthquakes are among the most powerful events on earth, and their results can be terrifying. Earthquakes in general does not kill people directly. Instead, many deaths and injuries result from the collapse of buildings, bridges, and other structures. We cannot prevent natural disasters from striking, but we can prevent or limit their impact by making buildings strong enough to resist their destructive forces. This can be achieved by earth quake resistant structures. In the case of earth quakes, it is possible to neutralize their harm by applying basic engineering and planning principles that are inexpensive. This paper deals with the explanation of basic engineering and planning principles to be taken into account during the construction of earth quake resistant structures. This paper mainly deals with (i) the various types of failures that are caused due to the vibrations during the earthquakes (ii) analysis of the failures and (iii) solutions for overcoming failures.

Key words: Earth quake resistant structures, Shear joint failures, Structural failures, Non Structural failures Site failures, Foundation failures, Lateral force resisting system.

1. INTRODUCTION Earthquake is the shaking of the ground caused by the sudden breaking and shifting of large sections of Earth 's rocky outer shell. Earthquakes are among the most powerful events on earth, and their results can be terrifying. The force of an earthquake depends on how much rock breaks and how far it shifts. Powerful earthquakes can shake firm ground violently for great distances. During minor earthquakes, the vibration may be no greater than the vibration caused by a passing truck. In order to construct earth quake resistant structures we need to analyze the way in which buildings respond towards the vibrations

    Earthquake is the shaking of the earth’s surface caused by rapid movement of the earth’s rocky outer layer. Earthquakes occur when energy stored within the earth suddenly releases, the size varies from small hardly noticeable shaking, to large shocks which can be felt from miles around. Earthquakes can tear up the ground, make buildings and other structures collapse, and create large sea waves; but our mind describe it as a natural disaster which can take all the happiness of our life and fill it with sorrow…
