DYNAMIC ANALYSIS AND CONDITION ASSESSMENT OF RC BUILDING BY VARYING MATERIAL DAMPING AND TIME DEPENDENT PROPERTIES

Latha H R, Syed Ahamed

Abstract: In the present dissertation study, an SMRF building situated in seismic zone-III having G+ 10 storey has been considered for performing linear dynamic or response spectrum method of analysis, to achieve and compare various results such as storey drift, storey displacement for considered DCON-2 and DCON-3 load combinations as per IS: 1893-2002 (Part-I), all imposed load are considered as per IS 875:2000. Also the condition assessment of the building models through system identification approach and extract the modal identification parameters like frequency, damping, mode shapes. Furthermore spectral displacement, spectral velocity and spectral acceleration are obtained for various percentages of damping i.e., 0, 5 and 10, for all the considered SMRF building models. The overall dissertation flow has been carried out to perform linear dynamic analysis (response spectrum method) for the parameters ELCENTRO, using the finite element method based analytical software ETABS-15 version.
