Working with load groups in SkyCiv構造3D

After you’ve finished modelling your structure you will want to apply loads to it. Most of the time you will want to group these loads together for a particular purpose to make your load combinations simpler. There is no way to add load groups, they are created at the same time as you add a load. S3D automatically names these as LGX where X = a positive number, however you can name these anything. 例えば: I would like to to apply a wind load to my structure, so I will name the load group W. Load Groups are not affected by load factors from load combinations because by themselves, they by default, are not assigned to a specific load case (dead/live/snow/wind/etc)

Example Workflow: Entering Load Groups and Assigning them to Load Cases

Lets go over an example so the workflow can be explained. 最初, you will want to apply a load. この例では, 私たちは適用します 10 kip load to a beam. Load Groups are used so users can distinguish between multiple different types of loads. Lets assume its a hanging load, so when applying the point load, 入力します “吊り荷” の中に 負荷グループ 分野, 次に、[適用] をクリックします.

load groups 1

の “吊り荷” Load Group is now defined. Any new load that is generated or applied will now have “吊り荷” as an option when selecting its load group.

注意: “吊り荷” is not attributed to a specific load case, we need to do that next.

To assign a load case to our new load group, に行く 編集する on the top toolbar and then down to 荷重ケースの割り当て. This window is where you will assign each arbitrary load group to its intended load case, which will differ from each code. この例では, we will be using load case nomenclature as set out by ASCE. Select the relevant design code and subsequent load case for each load group. We will assume that we want the hanging load to be designated as a Live Load, それを選択.

load groups 2

今、私たちは 1) defined our load groups and 2) assigned them to load cases, we can now move on to Load Combinations. これについては、 荷重の組み合わせ ソフトウェアのドキュメント.


Display Settings for Load Groups

Users can easily identify certain load groups using visibility settings on the right menu. ユーザーは色分けしたり、, or toggle the visibility for different load groups:
