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

VIBRATION - I Aim: To find the natural frequency of transverse vibration of the cantilever beam. Apparatus required: Displacement measuring system (strain gauge) and Weights Description: Strain gauge is bound on the beam in the form of a bridge. One end of the beam is fixed and the other end is hanging free for keeping the weights to find the natural frequency while applying the load on the beam. This displacement causes strain gauge bridge to give the output in milli-volts. Reading of the
