# Wind Load Calculator. If you need to change this value, check our air density calculator. ## Dynamic pressure and wind load. The **wind load calculator** enables you to **compute the wind force on any structure**. Whether it is a roof, a sign, or a steel structure, with this wind force calculator, you can determine the wind pressure created on it depending on the wind speed, helping you make sure it's sturdy enough to withstand even the worst storm. But don't worry; this wind force calculator is here to help you estimate the wind load exerted on any structure, depending on the wind speed and the structure's surface area. ## What is the wind load on a structure? The wind load also depends on the **effective surface area of your structure**. **Multiply** the *dynamic pressure* with the *effective surface area* of the structure to obtain the wind load:.

Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! # Wind Load vs. ## Wind load on surface - Wind load calculator. When moving air - wind - is stopped by a surface - the dynamic energy in the wind is transformed to pressure.

A major problem with Category 2 hurricanes is that winds are strong enough to break power poles, which can in turn create blackouts. Category 2 hurricane winds can also cause damage to residential roofs, windows, and doors. A Category 3 hurricane has winds of 111 to 130 mph. Category 4 Hurricanes Category 4 hurricanes are very strong, with winds of 131 to 155 mph. Category 5 Hurricanes A Category 5 hurricane packs winds of more than 155 mph. Should Category 6 ever become an official classification on a hurricane wind scale, it would likely include hurricanes with winds of 175-180 mph or greater. Trees can also be severely damaged by Category 1 hurricane winds, with large branches breaking and some trees being completely uprooted.

An official website of the United States government. # Quantifying the hurricane risk to offshore wind turbines. The U.S. Department of Energy has estimated that if the United States is to generate 20% of its electricity from wind, over 50 GW will be required from shallow offshore turbines. We apply this model to estimate the risk to offshore wind farms in four representative locations in the Atlantic and Gulf Coastal waters of the United States. Offshore wind turbines in these areas will be at risk from Atlantic hurricanes. To illustrate the risk to a wind farm from hurricane force wind speeds, we calculate the expected number of turbine towers that buckle in a 50-turbine wind farm as a function of maximum sustained (10-min mean) wind speed, assuming that turbines cannot yaw during the hurricane to track the wind direction (we later consider the case in which the nacelle can be yawed rapidly enough to track the wind direction of the hurricane).

# ASCE 7-10 Wind Load Calculation Example. SkyCiv released a free wind load calculator that has several code references including the ASCE 7-10 wind load procedure. In this section, we are going to demonstrate how to calculate the wind loads, by using an S3D warehouse model below:. In our wind load example, design wind pressures for a large, three-story plant structure will be determined. Below are the formulas in determining the design wind pressure. \(p = q{G}\_{f}{C}\_{p} -{q}({GC}\_{pi})\) **(2)**. \({C}\_{p}\) = external pressure coefficient. \({q}\_{i}\) = \({q}\_{h}\) for negative internal pressure, \((-{GC}\_{pi})\) evaluation and \({q}\_{z}\) for positive internal pressure evaluation \((+{GC}\_{pi})\)of partially enclosed buildings but can be taken as \({q}\_{h}\) for conservative value. \({K}\_{z}\) = velocity pressure coefficient. Moreover, we will be using the Directional Procedure (Chapter 30 of ASCE 7-10) in solving the design wind pressures. The first thing to do in determining the design wind pressures is to classify the risk category of the structure which is based on the use or occupancy of the structure.
