Seismic Response Evaluation for Gate-Type Twin Tower Reinforced Concrete Frame Structure

Abstract: As the population increases tremendously the horizontal space in urban areas are insufficient to construct a building so it is very essential to go for vertical construction. In this research The 11 storey gate type twin tower reinforced concrete frame building having the top three floors horizontally connected is analyzed by using finite element modeling software. By using linear static and dynamic analysis, the seismic responses are computed and compared for various models such as twin towers without any connection, twin towers with one-way connection, and a gate-type twin tower structure with the top three floors connected. It examines storey drift, displacement, and base shear in seismic zone III on medium soil. The results finds that structural responses to the gate building show both decreases and slight increases when compare to without connected buildings. So By connecting twin tower buildings, not only is an innovative architectural design achieved, but a roadway between the towers can also be provided., In addition, the horizontal space at the top floors after connecting the towers can also be used for residential, commercial, and office accommodation purposes.
