“…width of the structure can obviously influence the optimum locations of outriggers, the drift-reduction efficiency and the reduction efficiency of the moment at the base of core. (2) The optimum locations of all the outriggers move downward as the core-wall width increases. (3) The driftreduction efficiency and moment-reduction efficiency of the outrigger-braced structure increase as the core-wall width increases.…”

SummaryIn this paper, the governing equations of the outrigger‐braced structure are formulated by considering the influence of core‐wall width. The axial forces in the columns are considered as unknowns and the compatibility of the column's axial deformation is considered in formulating the governing equations. Then, the governing equations for the optimum locations of outriggers are formulated by minimizing the top drift of central core wall. After that, the influence of core‐wall width on the optimum outrigger locations, the drift‐reduction efficiency and moment‐reduction efficiency is investigated numerically. Some results are presented for the reference in the preliminary design of the outrigger‐braced structures.

“…The authors also described the implementation of these devices in the tall structural system and further explained the new contemporary structural forms and their Fig. 6 Virtual outrigger system using belt trusses [25] concept, their advantages, and disadvantages, their material, topology and size, number of stories, and scale of real example buildings that are coated for all the classification of structures with the location, and specification is also presented by the article [26,27]. The shortcoming of the tall building led to structural control practice to safeguard the skyscrapers battered by uncertainty.…”

This paper presents the development of the outrigger structural system from the conventional outrigger to damped outrigger concepts. Outrigger structural system development from the conservative design as a rigid connection to a virtual connection with passive control, active control system, semi-active control system to hybrid control system is deliberated. Following brief overviews on history of outriggers, types of the outrigger, analysis of tall buildings without outriggers, formulation of equations for outrigger structure to simplify analysis are elaborated. Different approach to locate optimum positioning of outriggers in tall structure is elucidated. Analysis of outrigger to study its behavior in high-rise buildings using different methods is stated, and review on the damped outrigger system is explicated. This paper tries to highlight the advantages of outrigger structure with semi-active control and performance enhancement of the outrigger system with the effective devices, and enhanced results are also depicted. This review also paves a way for the new area of research in structural control with the incorporation of smart devices and smart technology.

“…A Framed-Tube Structure (2) meanwhile, is about making benefit of the whole building perimeter to resist wind loads, in which columns are closely spaced and are connected with deep spandrel beams. To enhance the performance of a Framed-Tube structure, belt trusses are often used to equalize the load distribution and to minimize the effects of shear lag often experienced in such structures [15]. A Tube-in-Tube Structure (3) is when a core is added usually of shear walls for better performance against gravity and lateral loads.…”

This study is concerned with reviewing and analyzing methods used in early design stages to mitigate wind effects on high-rise buildings. In order to mitigate wind effects on structures and specifically high-rise buildings, early stage aerodynamic design decisions are made. Architects try to mitigate the wind effects on buildings by choosing the right form configuration like tapering or setbacks, etc., or by making vital decisions in the early design stage. However, structural engineers utilize the structural system that can best counter-act forces acting on the stability of the building. For both architects and engineers there are many tools which can be used in early design including advanced analysis methods, wind tunnel testing and wind studies combined with Computational Fluid Dynamics (CFD) simulations. This study reviews general architectural and structural design configurations performed in the early phases of the design process, for achieving structural stability, comfort and cost control. The research methodology depends on the study and analysis of different international building examples, and also by reviewing two local high-rise building cases in Amman, Jordan. The study concludes that there are many architectural aerodynamic configurations for the purpose of mitigating wind loads, which can be used as guidelines in the early design phases.
