Study of Multistoried Buildings with Oblique Columns

Abstract

Abstract- The Oblique Columns are not conventionally parallel or at right angles to a specified line means they're inclined or slanted or Rotated at an angle. Oblique columns are stiffer as RC frames and so the initial stiffness of the RC frames largely depends upon the stiffness of oblique column. For oblique column of below 900, there'll be a decrease in plan dimensions and for above 900, there'll be increase in plan dimensions as we reach upper floors. It affects the lateral stiffness of the buildings. Compared to standard columns, oblique columns of below 900 have lesser storey shear values. Oblique columns of above 900 have higher storey shear values. Stiffness of RC frames significantly depends on the distribution of oblique column within the frame. The lateral loads are resisted by structure with Oblique columns, the highest storey displacement is incredibly much less in Oblique structure as compared to the easy RC Frame building. Analyzing the behavior of oblique columns is that the main purpose of this study. Analysis has been meted out by considering columns of 80, 82, 84, 86, 88 and 90 degrees. Static and Dynamics analysis should be finished these Columns. Ground motion performance of oblique columns are analyzed by Response spectrum method. The analysis of the buildings will be done by using ETAB software and the performance will be analyzed by same building with oblique columns replaced with normal vertical columns. Analysis has been meted out by considering columns of 80, 82, 84, 86, 88 and 90 degrees.
