Shri. Balla Venu Kumar, Country Head/Wind Engineering Expert/Specialist, CPP Wind Engineering & Air Quality gave a talk on Wind Engineering on High-Rise Buildings and Civil Structures: The Benefits of Wind Tunnel Studies, IS875 and the International Code Wind Load Design limitations on 15 April under the IAStructE and IIIT Hyderabad’s monthly lecture series.
Wind interacts with buildings and structures in complex and often surprising ways. A structure`s geometry, the surrounding terrain, nearby buildings and structures, and seasonal wind conditions all influence the way wind will interact with a structure. Wind loading codes are primarily used for preliminary understanding and not for final design in wind sensitive Structures. Wind tunnel testing provides specific, customized information about a building or structure or any wind sensitive structures, making it a key tool for efficient design. The talk covered the effect of wind on the high-rise buildings and civil structures, imitations and conditions of International and IS875 codes, and the importance of wind tunnel tests.
The topics covered were :
- Codes and Standards –History, Limitations, Assumptions and conditions.
- Structural and Façade Failure design – Quick Overview.
- Importance of Wind tunnel testing.
- Site Study, Wind Climate, Influence of Terrain, Boundary layer profiles and Boundary Layer Wind tunnel.
- Proximity Model and Building Architecture influence on the wind loads.
- Wind tunnel test mitigation solution for higher wind loads.
- Wind tunnel structural and pressure/cladding studies and comparison to codes.
- Environmental Winds/Pedestrian Winds.
