Structural Response Enhancement by Optimized Outrigger Location

The human being shelters themselves in the man-made construction, which is temporary for all the natural hazards, as they damage the construction completely.Tall buildings are one such type, which has to be designed to overcome all the threats of nature.In tall buildings, outrigger structures belong to interior structural forms, which are designed to resist the lateral loads.The deep, stiff beam known as an outrigger connects the structure's inner core to its outermost column.The main advantage of the outrigger is that they reduce the horizontal structural moment, in turn; the core overturning moment is mitigated that reduces the uplift of the core.The conventional outrigger is surpassed by the damped outrigger, which is connected to the core rigidly and damper connections are provided in between the column and outrigger.The outrigger structure's performance also depends on the outrigger positioning in reducing the vibration of the structure.An analysis of the damped outrigger structure presented in this paper against the wind load is carried out.Therefore, the goal of this study is to use MATLAB to simulate and determine the best outrigger positioning to minimize the structure's displacement.
