Abstract

In the present study a investigation on the performance of a multi-outrigger structure subjected to seismic loads has been carried out. A three dimension model has been developed using the software ETABS. The relative height of the outrigger is varied and the performance of outrigger is then studied based on lateral displacement, storey drift, shear force and bending moment in the core wall for different values of relative axial rigidity (ratio of axial rigidity of the columns to the axial rigidity of core wall). When the displacement criteria is considered, a significant reduction in lateral displacement at top has been observed for the multi-outrigger structure for a relative height of 1.5 when compared with a structure without outrigger. When bending moment criteria is taken into account, there has been a considerable reduction in bending moment when the multi-outrigger structure with a relative height of 6.67 is compared with a model without outrigger .
