## 使用 “Select Worst Case Wind Source Direction” in Load Generator

Site analysis is crucial in wind load calculations. By conducting this analysis, we can determine the worst wind source direction to generate the largest design wind speed and pressures.

In the SkyCiv Load Generator, this can be done by clicking the “Select Worst Case Wind Source Direction” button. 然而, this is only available to ASCE 7, NSCP 2015, 和AS / NZS 1170 for now. Soon, we will be adding the other reference codes to aide your design process. The button will be enabled after the Basic Wind Speed has been pulled from our server.

Site data for wind load calculation.

By clicking the “Select Worst Case Wind Source Direction” button above the map image, it will generate the terrain sectors for each direction. It will generate the parameters for each direction and calculate the corresponding velocity pressures. Note that the radius of the sectors is equal to 2 miles for imperial units and 2 kilometers for metric units.

Initial values for the worst case wind source direction data.

The generated editable terrain/exposure category sectors in the map.

To update each Exposure or Terrain Category, you just need to click the sectors inside the Google Map. It will change its color to indicate that the Exposure/Terrain Category is updated and will also show the information of exposure or terrain category selected. After this process, just click the “Select Worst Case Wind Source Direction” button again to update the values in the table.

The updated terrain category for each direction.

You just need to re-click the “Select Worst Case Wind Source Direction” button again to check the changes. The maximum velocity pressure value in the table will be highlighted and can be clicked to automatically load the direction and the corresponding exposures/terrain category to the site data tab.

The updated parameters in determining the worst case wind source direction.

The elevation chart where you can modify the topographic factor/multiplier per wind source direction in the site analysis.

Once you’ve edited the elevation data per wind direction, you just need to re-click the “Select Worst Case Wind Source Direction” button to show you the changes in the the wind speed/pressure.

The updated velocity pressure after changing the topographic factor in the Elevation chart.

All of this process with just a few clicks! 通过以下方式利用此功能 注册专业帐户 或通过购买 独立的Load Generator模块!
