- How Tall Buildings Tame the Wind - The B1M
Corner softening sees sharp edges smoothed-off of a structure to make it more aerodynamic, or small cutouts created on the edges of an structure to “scramble” prevailing winds and reduce the strength of the vortices they create
- Effects of corner modification on the Strouhal number of high . . .
It was found that these three types of corner modifications are all effective in reducing the maximum mean and standard deviation of base force in the across-wind direction, with the reduction effect increasing as the corner modification rate increases
- Aerodynamic Modification and Shape Optimization of Tall Buildings
Chart-2 Storey drift values for corner modification improve the performance of building against wind The corner modification is like softening the building corner and it allows wind to move smoothly Among the studied corner modification triple recession is most effective in reducing storey displacement, followed by single recession and
- Performance-Based Wind Design of Tall Buildings Considering . . .
The results showed that inelastic wind design can be more effective than corner modification in the reduction of wind load; however, the design reinforcement ratio is less and more similar due to minimum requirement
- Wind Load Reductions due to Building Corner Modifications
For example, higher level openings, tapering, twisting the structure around its vertical axis or modifying the building corner details can be beneficial The latter is the focus of the present
- How Are Super Tall Buildings Engineered to Withstand High . . .
These massive pendulum-like devices are placed near the top of a building and are designed to sway in the opposite direction of the building’s movement caused by wind By counteracting these forces, tuned mass dampers help stabilize the building and reduce the sway that occupants would otherwise feel during high winds
- How do civil engineers build wind-resisting skyscrapers?
Another benefit of spiralling structures is the reduction of vortex shedding Vortex shedding is a phenomenon that occurs when the wind flows around the corner of a building, leading to the formation of alternating low-pressure zones that can cause the structure to sway
