| Abstract: |
The behaviour and stability of a multi-storey building in a sloped region depends on structural configuration. Irregularities in the structure are recognized as one of the chief sources of its failure. Structures commonly have a grouping of irregularities such as vertical irregularity, mass regularity, stiffness irregularity etc. Also, for the analysis of such a structure, it is necessary to carry out dynamic analysis to determine the maximum peak response of the building with respect to the natural time period. Since it would be difficult to get the time history record for all the places, it is feasible to go with Response Spectrum Analysis. In this paper, a G+4 RCC building having each storey of height 3.5m placed in the sloping ground with horizontal angle of inclination 20° for the purpose of dwelling of people during disaster with one of the storey to be used for storage of food and water which induces Mass irregularity. The structure is modelled in ETABS software. Here the mass irregularity is induced at every storey by inducing on one storey at a time for 3 different zones (III, IV, V) and the same has been analysed by inducing gravity loads and seismic load cases using Response Spectrum Analysis. The response of the structure with respect to variation in the Storey Drift and Storey displacement has been recorded and will be discussed elaborately. |
