# Concepteur de membres

## Obtenez les sections les plus optimisées pour vos conceptions, en un seul clic.

L'optimiseur de conception des membres SkyCiv fait gagner du temps aux utilisateurs, by adding checking every possible section in a given database and choosing the shape with the lowest cross sectional area and best utility ratio. Actuellement, l'Optimizer prend en charge tous les codes de conception SkyCiv (AISC, NDS, AISI, COMME, CSA, BS, Eurocode et plus…).

L'Optimizer existe sur tout notre acier, wood and cold formed member design software via SkyCiv Structural 3D, SkyCiv Beam et notre logiciel de conception autonome.

## Launching the Optimizer

En 3D structurelle, il existe deux façons de lancer l'Optimizer. d'abord, cliquez simplement sur leOptimiserbutton in the design module of your choice. Dans le modèle ci-dessous, nous utilisons un modèle en acier, qui a clairement des membres défaillants de l'AISC:

Second way is to simply highlight which members you wish to design, puis clic droit – Optimiser. Remarque: this will optimize these members’sections, not each member individually.

## Paramètres

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 theOptimiserbouton, the following options will appear:

### Variables

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

### Criteria

Users can input their own maximum utility ratio for the optimizer, this would mean that any result with a higher UR than specified will not be considered a valid choice. Users can also specify for the optimizer to minimize the section area as well, 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. Ici, ils peuvent également choisir d'optimiser leurs groupes ou d'optimiser leurs sections, within the model.

## Résultats

The results of each section will display in a popup, résumer la section sélectionnée, c’est le rapport d’utilité et les options d’engagement. In the below example, tout 7 sections du modèle. Un résultat a été trouvé pour tous les ID de section, sauf un. 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. Par exemple, 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. Dans l'exemple ci-dessus, 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.

$\bg_white&space;SFO&space;=&space;\frac{\sum&space;\frac{\text{Result}}{\text{\&space;Criteria}}}{\text{Number&space;\&space;of&space;\&space;Criteria}}$

Once you’re happy with the results, you can hitet Y se rapporte à l'axe yet cliquez 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. Pour cette raison, 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.
