Obtenha as seções mais otimizadas para seus projetos, em um único clique.
O SkyCiv Member Design Optimizer economiza tempo dos usuários, by adding checking every possible section in a given database and choosing the shape with the lowest cross sectional area and best utility ratio. Atualmente, o Otimizador suporta todos os códigos de design SkyCiv (AISC, NDS, AISI, COMO, CSA, BS, Eurocódigo e mais…).
O Otimizador existe em todo o nosso aço, wood and cold formed member design software via SkyCiv Structural 3D, SkyCiv Beam and our Standalone Design software.
Launching the Optimizer
Em 3D Estrutural, there are two ways to launch the Optimizer. em primeiro lugar, basta clicar noOtimizebutton 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, em seguida, clique com o botão direito – Otimize. Observação: this will optimize these members’Seções, 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 theOtimizebotão, 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
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
In this area of the settings modal, users can select their design code as they normally would in the Member Design module. Aqui, 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. In the below example, tudo 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:
*A linha vermelha indica que, 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. Isso exibirá a seguinte lista detalhada de corridas. Por exemplo, seção de seleção 3 (HSS) irá mostrar o seguinte:
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. No exemplo acima, 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 hitAgora continue e adicione os quatro nós a seguir para completar o quadro de empenae clique 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. Por esta razão, 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.
