Wind Structure

1. WINDANALYSIS
OF
STRUCTURE

2. Why wechoose thistopic:

3. Wind is a horizontal movement
of free air.
It plays an important role in
design of structure because it
exerts load on building.

4. HOWWINDWORKS:

6. Collapse due to wind load

7. Increasing tallest structure rapidly

9. Top TallestBuildings:
Toronto's_CN_Tower
Tokyo_Sky_TreeHong kong’s Twin Tower

11. TYPES
OF
WINDSTORMS
Rotating wind
Non-Rotating wind

12. TORNADO(486km/hr)

13. HURRICANESTORM(120km/hr)

14. CYCLONIC STORM(400km/hr)

21. WINDLOADAFFECTED
STRUCTURES:
Tocoma Bridge, US
(68km/hr)

22. Cyclone HUDHUD, AP
(195km/hr)
Bihar
(155km/hr)

23. Some examples are given into the following data where
various economic and many peoples died due to
affects of windstorms….>>>>>>>>>>>>>
 86,000 peoples were died at Banquiu dam in
china,1975
 226 peoples were died at Angers bridge in
France,1850
 120 peoples were died at Amarube rail road bridge
in Japan,1986

28. Precaution:
Wind pressure is the principal force tending to
disturb the structure stability of isolated walls
greatest stress produced is at the bottom of a
wall where the wind exerts the greatest turning
moment.
Equating the resisting moment of the wall to the
moment due to wind pressure.
Unsymmetrical walls can be divided into two
separate and each block tested for structural
stability as an independent unit.
