Comparative analysis of multi storey mono column structures for different plan configuration with same plan area

Abstract

Wind load and Earthquake load play an indispensable role in structural analysis. Many research works carried out on analysis & design of single column structures. Being inspirit from the previous works on effect of earthquake and wind load on single column structure, this paper presents effects of six different plan configurations i.e., Square, Rectangular, Circular, Triangular, Pentagon and Hexagon with same plan area (144 m2). Mono column structure with different plan geometry react adversely in contrast to earthquake and wind loads. Modelling, analysis and design of Multi storey mono column structure is done by using CSI ETABS software. Seismic and wind analysis has been done and maximum values of Storey displacement, Storey drift, Storey shear, overturning moment, Storey stiffness and Time period results are manifest in form of figures. The purpose of this analysis is to determine the most effective and vulnerable shape of structure in prone areas. Storey displacement, storey drift values are minimum in circular shape structure in all seismic zones. Storey shear, overturning moment, storey stiffness is minimum in square shape structure, maximum in triangular shape structure. Time period is maximum for mono column structure with rectangular plan configuration.
