Integration between SkyCiv Structural 3D and Load Generator helps bridge the gap between load calculation and load application. With this integration, users can automatically generate loads in the Load Generator module, then apply them directly to their model in Structural 3D. This functionality is integrated directly in Structural 3D, so no need to go to any separate modules before hand. 后来, SkyCiv recommends completing the modeling stage of your structure before engaging in any Load Generator applications, as it will increase the overall accuracy of the process.

The following types of code-generated loads are available to be directly applied to models in Structural 3D

  • 风荷载
  • 积雪
  • 地震荷载 (in development)

Before going into this article, SkyCiv HIGHLY recommends going through the Software Documentation on Modeling in Structural 3D, 区 & 风荷载, as well as be familiar with the use of the standalone 负载产生器, as all of those functions are relevant. This documentation will focus on the application of the loads using the integrated version of the Load Generator while operating in Structural 3D. 所以, this documentation won’t go into depth on how to calculate each individual load, as they are very reliant on which code you are using. 如上所述, please go through linked documentation on the Load Generator and the prevailing building code, before going through this article.

To use the integrated Load Generator, finish modeling your structure, then go to 区域负荷 on the left input tab while operating in Structural 3D. 然后, click on the red 负载产生器 纽扣.

注意: The simpler the structure is, the easier the integrated application will be. The more complex the model, the less accurate the application of the loads will be.

Applying Wind Loads from the Load Generator

At first glance you will notice that the full standalone version of the Wind Load generator now inhabits the left input side of the screen. Users enjoy all of the same functionality in the integrated version as they do in the standalone version. Things such as saving your calculation and printing site and wind load reports can be accomplished here. In the integrated Load Generator, the Structural 3D model will always be displayed on the right hand side of the screen.

As you go through the inputs the same as in the standalone version, you will notice some things will be auto-populated, thanks to your model being present in this integrated format. 例如, once you get to the 建筑数据 portion and have selected a few of the classification or building type options (depending on your code version), most of the building dimensions and roof angles will automatically be filled in based on the geometry of your model. Any of the fields in the 建筑数据 要么 网站数据 can be adjusted manually as well.

Once all of the available inputs are satisfactory, 点击 生成载荷 纽扣. The solver will then try to take the loads that are generated from the integrated Load Generator, and apply them directly to your structure. Each pressure value according to a face of the structure (again, depending on your applicable code) will be identified by a series of nodes. These nodes are found in the 节点编号 柱子, and are responsible for outlining the extents of each pressure. Any of these node sequences can be edited to apply that wind load to whichever face you want.

You should see that loads that were able to be generated and applied will show up in the 3D model space directly on your model. Each load case will be shown at the same time, so it might be harder to see what is going on. At the same time as the generator being open, you can toggle on and off the different load cases as well as hide or isolate members in the model space using the same visibility settings and tools available in Structural 3D.


If SkyCiv’s solver was not able to create a direct link between your model and the generated wind loads, that instance will be left blank, and you will need to input these node values manually. The simpler the model, the less manually input required, 反之亦然.

负载生成器 2Because the generated wind loads take the form of 柱风荷载, they can always be viewed and adjusted individually like any Area Load by going to the Area Loads tab on the left hand side and then clicking on the Datasheet:

负载生成器 3

一个 important note about Generated Wind Loads:

All of the generated Wind Loads take the form of 柱风荷载 (discussed in the Area Loads documentation) while present in Structural 3D. 因为这, the order the nodes inputted into each field DOES matter. 柱风荷载 distribute to their subsequent members using One-way distribution. The first two nodes indicate the 跨度方向: basically the direction of the members constrained within the load that should see the distributed load of the member.

SkyCiv highly recommends checking out the “例: 柱风荷载” section of the Area and Wind Loads Software Documentation article for more in-depth information about this.

Modifying or Resetting Loads

If at any point during the application of these automatically generated loads you want to change the underlying parameter values, or start over, you may do so. To change or reset the loads, 去 区域负荷 > 负载产生器 as if you were going to apply the loads the in the first place, and you should see this message:

  • To start over, hit the Reset 纽扣.
  • To adjust the values for previously calculate loads, hit the Use Previous Data 纽扣.

Both options will bring you back to the integrated load generator page. To make any changes applicable to the model, make sure to hit the Generate Load button again. Also note, the small “X” button that is next to the Generate Load Button will clear any automatically generated loads from the model.
