SkyCivメンバーデザインオプティマイザーはユーザーの時間を節約します, by adding checking every possible section in a given database and choosing the shape with the lowest cross sectional area and best utility ratio. 現在, オプティマイザーはすべてのSkyCivデザインコードをサポートします (AISC, NDS, AISI, なので, CSA, BS, ユーロコードなど…).

オプティマイザーはすべての鋼に存在します, wood and cold formed member design software via SkyCiv Structural 3D, SkyCiv Beam and our Standalone Design software.

Launching the Optimizer

構造3D, there are two ways to launch the Optimizer. まず, をクリックするだけです最適化button in the design module of your choice. In the below model, we are using a steel model, that clearly has some failing AISC members:


Second way is to simply highlight which members you wish to design, 次に右クリック – 最適化. 注意: this will optimize these members’セクション, not each member individually.




Users have a number of controls and settings available, including a targeted Utility Ratio, Section Height/Width limits and which sections you wish to design. By clicking the settings button next to the最適化ボタン, the following options will appear:



Users have the option to choose between all the sections from the library, a range of section heights or widths. These options will govern what sections, the optimizer looks at when selecting the most optimized section


ユーザーはオプティマイザーの最大利用率を入力できます, これは、指定されたよりも高い UR を持つ結果は有効な選択とは見なされないことを意味します。. ユーザーは、オプティマイザーがセクション領域を最小化するように指定することもできます, it will then find the balance between the highest possible utility ratio and the smallest section area

Member settings

In this area of the settings modal, users can select their design code as they normally would in the Member Design module. ここに, they can also choose to optimize their groups or to optimize their sections, within the model.


The results of each section will display in a popup, summarizing the selected section, it’s utility ratio and options on committing. 以下の例では, 全て 7 sections of the model. A result was found for all section IDs, except one. The minimum working section for this shape had a Utility Ratio of 1.115:


*The red line indicates that, even the biggest section area could not withstand the loading conditions

We can take a closer look at all the runs and their results by clicking the icon underIterations. This will display the following detailed list of runs. 例えば, selecting section 3 (HSS) will show the following:


From here we can sort by Max UR, cross area and SFO (a weighted index) which will show the best result based on your predetermined criteria (in settings). This allows users to review the optimization runs to make sure the right section has been selected. 上記の例では, we set a max Utility Ratio of 0.95 and a desire to minimize the cross section area.

SFO for each result is calculated as shown below.

Committing your Results

Once you’re happy with the results, you can hit左側のメニューバーをクリックします Commit Changesto accept those sections. The software will commit these shapes in both the Design module, and your Structural Model. The software will also re-run your design check to give you the most up to date results. So in our above example, after committing we can see the sections are all working (except for the one section which was over loaded):


Changing your section from the design mode, will mean that your analysis results are out of alignment with your current model. このために, we highly recommend going back and resolving your model and re running the design check to ensure your analysis and design results are in sync.
