Designer dei membri

Ottieni le sezioni più ottimizzate per i tuoi progetti, in un solo clic.

Lo SkyCiv Member Design Optimizer fa risparmiare tempo agli utenti, aggiungendo il controllo di ogni possibile sezione in un dato database e scegliendo la forma con l'area della sezione trasversale più bassa e il miglior rapporto di utilità. Attualmente, l'ottimizzatore supporta tutti i codici di progettazione SkyCiv (AISC, NDS, AISI, COME, CSA, BS, Eurocodice e altro ancora…).

L'ottimizzatore esiste su tutto il nostro acciaio, wood and cold formed member design software via SkyCiv Structural 3D, SkyCiv Beam e il nostro software Standalone Design.

Launching the Optimizer

Aggiunta rastremata, ci sono due modi per avviare l'ottimizzatore. in primo luogo, basta fare clic suOttimizzarebutton in the design module of your choice. Nel modello sotto, stiamo usando un modello in acciaio, che ha chiaramente alcuni membri AISC in mancanza:

aisc-member-design-optimization-run-failed-result

Second way is to simply highlight which members you wish to design, quindi fare clic con il tasto destro – Ottimizzare. Nota: this will optimize these members’sezioni, not each member individually.

right-click-optimize-member-design

 

impostazioni

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 theOttimizzarepulsante, the following options will appear:

member-optimize-settings

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. Qui, they can also choose to optimize their groups or to optimize their sections, within the model.

risultati

The results of each section will display in a popup, summarizing the selected section, it’s utility ratio and options on committing. In the below example, tutti 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. Per esempio, selecting section 3 (HSS) will show the following:

optimization-run-results-aisc-skyciv

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. Nell'esempio sopra, 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 hite Y si riferisce all'asse ye fare clic 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):

AISC completo

Changing your section from the design mode, will mean that your analysis results are out of alignment with your current model. Per questa ragione, 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.
