Effect of column location on plan of multi- story building on shear lag phenomenon

Abstract

Additional corner columns, if provided in tubular multi-storied buildings, may stiffen the buildings as a whole and this serve many other functional requirements. The objective of the present study is to investigate the effect of such additional corner columns on shear lag effect. The variations of axial forces at the column base and lateral deflections of the buildings with varying plans are calculated for the two different wind loading conditions, viz., IS 875- (Part3) 1987 and 120kN/m uniform loading. It is concluded that these additional corner columns, though small in number, are capable to significantly increase overall rigidity against wind load and results into reduction of shear lag effect.
