In the realm of structural engineering, optimisation is a key tool that unlocks the potential to create designs that are both efficient and cost-effective.
It involves the systematic exploration of various design possibilities to find the best solution that meets specific criteria. From maximizing strength to minimizing material usage, optimisation techniques play a pivotal role in achieving optimal structural performance.
In this blog post, we'll delve into some of different types of optimisation available to structural engineers, highlighting their uses through real-world examples.
-
Topology Optimisation - This type of optimisation focuses on determining the optimal layout of material within a given design space to achieve desired structural performance. By removing excess material, engineers can design lightweight yet strong structures. Topology optimisation has traditionally been especially useful in industries like aerospace, where weight reduction directly impacts fuel efficiency and overall performance.
-
Shape Optimisation - Shape optimisation involves altering the geometry of a structure to improve its performance. This can include adjusting dimensions, curves, and angles to optimize load distribution and stress concentrations. One notable application of shape optimisation is in bridge design, where section geometry can be optimised for any number of constraints in the properties of the section, but also constraints on fabrication or transport.
-
Size Optimisation - Size optimisation revolves around determining the ideal dimensions of individual structural components to meet specific criteria, such as minimizing deflection or maximizing load-bearing capacity. In civil engineering, size optimisation is already often employed in the design of steel sections or prefabricated concrete sections for buildings, purely through the selection of appropriate catalogue sections. By optimizing the size of columns, engineers can ensure structural efficiency while reducing material costs.
It's not just about the product
Optimisation techniques aren’t all about technical constraints. In fact, these techniques can offer a powerful means to save firms valuable time, resources, and money. By employing these techniques, businesses can streamline their design processes and enhance overall efficiency.
A well implemented optimisation process helps engineers quickly identify the most efficient structural configurations, reducing the need for time-consuming trial and error. This accelerates the design phase, enabling firms to meet project deadlines more effectively.
These techniques can also reduce many of the tedious tasks associated with the design process, allowing engineers to focus on more creative aspects of their role.
Conclusion
Optimisation techniques empower design consultants to navigate the complexities of structural engineering with precision and effectiveness. By swiftly identifying optimal designs, conserving resources, and curbing unnecessary expenditures, these techniques enable consultants to deliver high-quality solutions while saving their clients and their own business valuable time, resources, and money throughout the design process.
