Effect of Connecting Bridge on Axial Force in Corner columns of Structurally Coupled Tubular Buildings

摘要

Present paper describes the effect of connecting bridge on axial force in corner columns of structurally coupled tall buildings. To study the effect of structural coupling on the structural response of two high rise buildings, linear static analysis is carried out using STAAD PRO software. The structural system adopted for the building is tube in tube, each of the two buildings is square in plan with dimension as 30mX30mX180m. The wind loads considered for the analysis are obtained from experimental tests conducted in (Boundary Layer Wind Tunnel BLWT). The two buildings are connected by one skybridge / two skybridges, with dimension of each skybridge as 30mX6mX3m. The bridge is located at different levels. Due to presence of connecting bridge the structural response is modified. The results of these studies are presented in the present paper. It is observed that the connecting bridge does not have much effect on the axial force in columns.
