In a multi-functional tall building, generally the building has a more extensive plan area and higher lateral resistance at the lower story level than the above story levels. So, the scope of this study is to understand the realistic behavior of such structures under lateral loads considering the backstay effect as per IS: 16700(2017). A Sensitivity Analysis was performed as per IS: 16700(2017) provisions by considering the stiffness parameters given in code to understand the changes in the shear force distribution among structural elements when the tower and Podium are modeled together. The changes in the force distribution are compared with the structure without the backstay effect. At the podium-tower interface level, the amount of backstay forces developed is also presented in this paper, along with the impact on backstay forces with changes in the lateral resistances by changing floor diaphragm thickness and by changing the podium area.
