“…Many researches stated that the structural optimisation of a tall building is greatly influenced by wind load [64][65][66] [67]. Besides, for tall buildings, the shape of the building plays a key role in controlling the effect of the wind load [68]. The above facts justify the emphasis on wind load in calculations and design of the PoC in this study.…”

Despite the unprecedented permeation of Building Information Modelling (BIM) and collaboration platforms, architects and structural engineers, for the most part, act as separate entities. That is, linking architectural models with that of structural engineers remains labour-intensive and cumbersome; structural engineers can generate few alternatives for any given architectural model. This paper is an attempt to address these problems. It provides an automated procedure, computational details and the configuration of toolsets in the form of a proof of concept (PoC) prototype that: binds architectural models with structural ones for tall buildings; automatically generates and updates alternatives for structural models, based on the input extracted from the architectural model; and provides engineers with an optimum design that fulfils the set criteria. The prototype is developed based on an initial need assessment study -to determine the requirements of practitioners. The practicality of the solution is assessed in a case project. The paper contributes to the field by presenting ones of the first solutions capable of automated generation of optimised structural design based on architectural models. Designed for tall buildings to incorporate immense complexity, the solution acts as a blueprint in developing similar systems for simpler buildings.

“…According to Holmes [19], Chamfered models reduce the across wind responses by 30% when compared to the model without modification. Corner-cuts performance is largely dependent on velocity [20], and also on location, where different terrains and different urban settings and neighboring buildings can have effects on turbulence of vortices [21]. One of the most demonstrative examples of using this configuration is the Taipei 101 tower in Taiwan, completed in 2004.…”

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.

“…Tall buildings, as per Xu et al (2014) are more prone to wind vibrations and receptive to dynamic loads. Further, Zheng et al (2018) stated that from the improvement of cross-section, the buildings enhance their wind resistance. Wind-induced accelerations, as mentioned by Farouk (2016) might cause discomfort to the occupants and so are taken into account as one of the most utility criteria whereas designing tall buildings.…”

“…Because of the many flow situations originating from the interaction of the wind with the structures, wind analysis is a task of high unconventionality if the building's plan is unusual. A collection of experimental and numerical work has been carried out to investigate wind-induced effects on isolated objects with various indifferent external shaped tall buildings, like Chakraborty et al (2014) and Raj and Ahuja (2013) have explored "+" shape buildings, Paul and Dalui (2016) investigated "Z" shape buildings, Gomes et al (2005) investigated "L" and "U" shape buildings, Mallick et al (2019) have studied "C" shape buildings, Li et al (2017) have examined "L" shaped buildings, Bhattacharyya et al (2014) have investigated "E" shape buildings, Nagar et al (2020) have analysed "H" shape buildings, Alminhana et al (2018) have considered "CAARC tall building model" with corner modifications, Bandi et al (2013) have investigated "Triangular" shape building with diverse configurations and Pal et al (2021) have investigated "Fish-plan Shape" model. The majority of researchers' interference studies, according to the existing literature, are aimed to determine the most useful configuration settings and/or interspacing among the obstructing models of rectangular or square plan shape buildings, as mentioned in the studies by Lam et al (2011), Hui et al (2012, Zu and Lam (2018a,b), Yu et al (2015), and Mara et al (2014).…”

The current investigation focuses on the results of an experimental investigation of Square-plan-shape and Remodel-triangle-shape building model's varied interference conditions between duplicate building models of 1:300 scale (at 100% blockage) on wind-induced pressure and base moments at fixed 10% of the height of the instrumented model. Under current working conditions, the study concludes that -1 > Interference Factor > 1 as experienced by the Remodel-triangle-shape model results in reduced performance of the instrumented model as opposed to the Square-plan-shape model. Front-to-Front interference condition of Remodel-triangle-shape model has the best overall performance in along-wind and crosswind directions, whereas Front-to-Back interference condition of Remodel-triangle-shape model has the best torsional performance. Back-to-Back interference of a Remodel-triangle-shape model should be avoided because the orientation of duplicate models attracts the most overturning moments in both the along-wind and crosswind directions of all interference conditions investigated in this study.
