When it comes to wind load calculation formulas, relevant architects are still relatively unfamiliar. What are the general wind load calculation formulas? How to use it? The following is the basic content of wind load calculation provided by Zhongda Consulting for construction professionals. The specific content is as follows:

Zhongda Consulting has compiled the knowledge from the construction knowledge column of this website. The basic overview of wind load calculation is as follows:

< p>Wind load is the pressure caused by air flow on engineering structures. Wind load is related to factors such as basic wind pressure, topography, ground roughness, height from the ground, and building shape. The strong winds caused by China's geographical location and climatic conditions include: typhoons on the southeastern coast in summer, thunderstorms and hail line gales in the interior; cold wave gales in the northern region in winter, among which typhoons in coastal areas are often the main control load in the design of engineering structures. Typhoons cause many wind disaster accidents and have a wide range of impacts. Thunderstorm winds may cause wind disaster accidents in a small area.

Commonly used calculation formulas for wind load:

The standard value of wind load perpendicular to the building surface should be calculated according to the following formula:

1 When calculating When the main load-bearing structure is the main load-bearing structure, press the formula: wk=?z?s?zWo

In the formula, wk? standard value of wind load (kN/m2); z? wind vibration coefficient at height z; s? wind Load type coefficient; z? Wind pressure height change coefficient;

Wo? Basic wind pressure (kN/㎡).

2 When calculating the envelope structure, follow the formula: wk=?gz?sl?zWo

Where?gz?The gust coefficient at height z; sl--wind load Local body shape coefficient.
