Various types of wind design codes used in the building design all over the world as per the standards

Wind is the horizontal force which acts perpendicular to the gravity loading condition. The wind load is also called as lateral loading condition system. Due to this force the damages will be more sometimes because of the higher velocity values. As per the standards which is provided by the various types of wind codes provisions all over the world the effect of wind force is more when we going from the bottom storey to the top storey of the building. In this blog post you are able to learn about what are the various types of wind design codes used in the structural design as per the various country regions. This concepts will give you better idea regarding the name of the code and number of the code and year of the code provision too.

As per the code provisions it is also suggested that if the height of the building exceeds the 10m then we need to consider the wind loading effect otherwise it is not mandatory. In simple words if the height of the building greater than 10m or greater than G+2 building structure we need to consider the wind loading effect and if the height of the building is less than 10m or for Ground floor or G+1 or G+2 structures no need to consider the wind loading considerations.

The wind loading intensity on the buildings will acts in two cases one is related to the wind ward facing direction and another one is leeward facing direction. If the loading condition is acting towards the building structure from the environment it is comes under the windward direction case. Sometimes the wind load will acts from the building structure this will happens if the internal forces are having higher intensity values than the external forces. The wind load which is transferred from the inner structure to the outer structure is called as leeward direction case.

The intensity of the wind loading condition is also effects on the obstacles which are presented near to the construction site. The height of the obstacles or height of the hill regions or height of the trees are considered as the factors in the wind loading calculations. These parameter consideration is also called as terrain categories. The complete concepts of the various terrain categories considered in the building design are presented in my previous blog post read them with below specified link. The terrains are classified in to four types related to the terrain category 1, terrain category 2, terrain category 3 and terrain category 4. The intensity of wind load is more in case of terrain 1 case because of less height of near structures and obstacles. In the same process the intensity of wind load is less in case of terrain 4 case because of more height of near structures and obstacles.

Conclusion of various codes used in the building design all over the world as per the standards

The wind is the horizontal force which is act for the buildings or other structures in lateral direction. As per the best design considerations it is important for the structural designer to select proper wind standards as per the requirements of the structure requirements. The various types of wind design codes used in the world are comes under twelve type which are related to the ASCE 7-16, AS/NZS 1170.2:2011, Chinese 2010, EUROCODE1 2005, Indian 875: 2015, Italian NTC 2008, KBC 2016, NBCC 2015, TCVN 2737: 1995, Turkish TS 498-97, BS6399-95 and Mexican code standards.
