Wind interference effect on an octagonal plan shaped tall building due to square plan shaped tall buildings

Wind Interference Effect on Tall Building

When a building is located in an urban area, it is exposed to a wind of different characteristics then wind over an open terrain. This is development of turbulent wake region behind an upstream building. The interaction with upstream building can produce significant changes in the response of the tall building. Here, in this paper, an attempt has been made to study wind induced interference eff...

Interference effects of wind loads on a row of tall buildings

ABSTRACT: We apply CFD to visualize wind flow around a row of three square-plan tall buildings closely arranged in a row. Increase in wind load on the upwind building is observed when wind blows to the row at 30. CFD results show that the interference mechanism is mainly due by strong channeling of wind flow through the building gaps. This leads to highly negative pressures on building walls fa...

Numerical Simulation of Interference Effect on Dynamic Wind Loading of Tall Buildings in Close Proximity by Large-eddy Simulation

We attempt to compute the dynamic wind loads on tall buildings in close proximity with large-eddy simulation. Computation is attempted on two building geometries on which strong interference effects have been reported in previous wind tunnel studies. The computation uses a commercial code and a simple model of turbulence characteristics of the incident wind flow. The computed along-wind and acr...

Learning Design Rules for Wind Bracings in Tall Buildings

This paper describes a methodology for applying machine learning to problems of conceptual design, and presents a case study of learning design rules for wind bracings in tall buildings. Design rules are generated by induction from examples of minimum weight designs. This study investigates the applicability of machine learning methods which are capable of constructive induction, that is of aut...
