INNOVATIONS IN EARTHQUAKE PROOF STRUCTURES

ABSTRACT

The objective of our paper is to put forth innovations in earthquake proof structures . Different methods have been developed all around the world to reduce the effect of earthquakes on buildings for reducing the losses , some of the innovations have been discussed in this report . The innovations we have covered in our report are Geogrids, Carbon fibers and Base isolation technique . We have presented base isolation technique in detail . Base isolation is an effective way to protect large structures from earthquake damage. It is a costly approach, as the entire structure must be supported on elastomeric or sliding bearings. Viscous dampers distributed throughout an otherwise conventional structure can achieve the same result at significantly lower cost. This paper describes how to install viscous dampers in a structure, and gives several examples. Further the paper describes fluid viscous damping, and shows how it works and how it can benefit a structure. A detailed description of a typical fluid viscous dampers comes after this, followed by a comparison of base isolation and fluidic damping as ways to reduce earthquake excitation of structures.
