Testing and Research
Wind Tunnel Tests
We can evaluate the design wind load for planned buildings and estimate the wind environment around high-rise buildings using wind tunnel trials.
To study building behavior in strong winds, a boundary layer wind tunnel with an open-circuit configuration is installed.
Major testing and research activities
- ■Scale model tests for measuring wind streams.
- Predicting and measuring wind velocity around high-rise buildings.
- ■Scale model tests for measuring wind pressures.
- Measuring wind pressure on buildings with cladding to determine wind loads.
- ■Scale model tests to measure and analyze building responses.
- Measuring the dynamic response of tall buildings induced by wind and calculating wind loads for structural members.
- ■On-site measurement.
- Measuring wind directions, velocities and wind pressures related to existing buildings.
- ■Numerical simulation of wind streams.
- Numerical analysis on wind stream around a high-rise building by means of computers.
