SHOCK ISOLATION AND ENERGY DISSIPATION IN STRUCTURES DURING EARTHQUAKE

Abstract

For a good dasiyn of a vibration isolator for a structure it is nacessarl to evaluate the chfscteristics as vall as significant -paraastrrs of the isolator. In the passant stud►, the parsa.tsrlc study is carried out with a view to lieud the properties of isolator for optfmua response reduction of =In structure, The response spectra for two degree lraMMes cysts has been constructed. Using the response spectra a nres the matbod of sslacting a isolator which will give the optima reductions in response of structure to be isolated, is given. The two degree response spectra curves can be used for analysis of the structure sounted over, the isolator for which the single degree response spectra curve is not very accurate as in generals the stiffness of, tin seen structure will be greatly different from that of the isolator.
