Wind Engineering Study

Why do we need wind tunnel study?

Wind tunnel studies helps in enhancing the reliability and cost effectiveness of the structural design especially unique or unusual architectural shapes which are not specified on standard code, besides this wind tunnel study helps in:

•

Ensuring the occupant comfort to motion sickness due to wind-induced motion.

•

Optimizing façade design in terms of cost effectiveness and risk of façade failure.

•

Accurately obtain wind effects at specific site by incorporating proximity buildings and terrain

•

Verifying and improving pedestrian comfort and safety at public outdoor areas for their

features.

Wind Engineering Study

What we offer?

AIT Solutions established in Asian Institute of Technology, Thailand has been involved with projects of varying complexities to conduct wind engineering studies, which includes wind effects on structures, aero elasticity, and wind tunnel model tests.

Wind Tunnel Study

Wind Tunnel Model

Wind Tunnel Data and Analysis

To: accurately estimate the wind model for the specific site.

By: statistical analysis together with historical ind speed information and roughness changes experienced by wind passing by proximity buildings.

Proximity Model

Overall Structure Loads

To: reproduce actual wind condition around the target site.

By: building proximity models of buildings or wind blocks of surrounding area with min. radius of 400 m..

To: obtain dynamic building responses of the proposed development.

By: measuring base shear forces, base overturning moment and base torque, which are then combined with structural properties of the building.

Force Balance Model

Cladding Pressure Studies

To: have very high natural frequency By: using light-weight foam and high-modulus string at the center.

To: achieve an accurate estimate of the design wind load on cladding panels.

By: by measuring local wind-induced pressure across the external surface of the proposed building incorporating with internal pressures considering potential effect of window breakage.

Pressure Model To: meet high degree of accuracy which also includes detail architectural features.

By: using rapid prototype technique a model is built which is then instrumented with large number of pressure measuring taps connected to peumaic tubes.

4

Environmental Wind Studies To: ensure pedestrian safety and comfort.

By: using Irwin-probes to measure wind speed at pedestrian height at different key areas both ground and/or elevated levels such asthoroughfares, entrances, outdoor seating, and public areas.
