EARTHQUAKE PROOF BUILDING
Principle of Earthquake Proof Building: - The principle we use
here in based on the first law of Newton's first law of motion
which state's that a body at rest will remain at rest and body in
motion will always be in motion so long as no external force occur
to change that state. Now in our project we are concerned with the
first part of the law only i.e the body at rest will remain at rest if
there is no external forces' acting on it.
If we are able to keep our building at rest by some means then we
can achieve our objective.
Principle of Construction: - First of all we need two metallic
chassis of same size one above the other. Between this chassis
there are several concave trays facing one another one from the top
and one from the bottom. Between this concave trays we sand
witch a metallic spherical shells. These sets of balls and trays are
placed and bolted along the entire length and breadth of the
chassis and along the cross members of the chassis.
This sets of ball trays can be replaced as and when required. Sir,
this idea can be applied for the construction of few storey's
building only.
Working Principle of E.P.B: - During earthquake the lower chassis
shares the motion of the ground and just rolls under the balls
while the upper chassis remain more or less at most obeying
Newton's law of Inertia.
Further more to enhance the stability of the building we attached
four gyros one on automatically using electric motors and
electronic device. As the materials are not avoidable they are not
used here.
This simple idea can be used for the construction of nuclear power
station and other dangerous installation.
Explanation About Model: - Here we used glass marble as metal
balls and teaspoons as metal concave trays. These chassis are
made of wood and also the rest of the building.
When the under sides chassis in proved and pulled rapidly, the
upper chassis and the building just remain more or less at rest and
ensuring safety.
This simple and novel ideal solution if adopted and implemented
will save a lot of lives and properties.
