SLIDING AND OVERTURNING OF OBJECTS DURING EARTHQUAKES

Abstract

The objective of thL a thesis is to evaluate the ground motion' characteristics such. es peak ground acceleration and predominant frequency during an earthquake by simple measu'► cements of objects which slid or overturned during the event. t`haro accolorograph record is available# the information fron sliding and overturning of objects may be used to supp. lement the accelorogram for working out the attenuation chap• racteristics of the affected area For achieving the objec. tivo stated above, simple objects were shaken on a shake table and observations of eliding and overtuining taken along vA th the record of table motion., A `t or digitising the table motion, response Gf friction mounted objets has been calculated by computer, progr rues made for the purpose. The correlation obtained botwen the observed and calculated values is quite promising though not entirely satisfactory.
