Present study describes the effect of connecting Sky Bridge on axial force in corner columns, internal columns
and central columns of structurally coupled tall buildings. To study the effect of structural coupling on the structural
response of two high rise buildings, Response Spectrum is carried out using STAAD PRO v8i software. Frame structural
system is adopted for the building having just beams and columns, each of the two buildings is analysed for different
shapes in plan like square, rectangle & C shape with dimension of grid of beams and column as 5m x 5m. Zone III &
damping coefficient 5% is considered in the analyses. The two buildings are connected with one sky bridge, two sky
bridges and three sky bridges, with length 5m. The bridge is located at different levels. Due to presence of connecting
bridge the structural response is modified.
