This document discusses wind analysis and its importance in structural design. It notes that wind exerts load on buildings and can cause collapse. Various types of windstorms are described, including tornadoes, hurricanes, and cyclonic storms. Examples of structures impacted by wind loads are provided, such as bridges and buildings. The document emphasizes that wind pressure is a key force that can compromise structural stability, especially at the base of walls. It concludes that using wind load design in structures can help reduce building collapses over time.

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

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.
