Structures that duplicate a large number of identical or similar modules will substantially reduce manufacturing costs and greatly simplify the assembly process.
This project has been funded by the Australian Research Council under its Discovery Projects funding scheme (Project No. DP1094401).
Many architectural designs incorporate periodic or repetitive geometrical patterns and they often exhibit a distinctive aesthetic appeal. New techniques for the optimal design of periodic structures will enable architects to create innovative and efficient structural systems. The developed algorithms from this project can be applied to not only large scale structures such bridges and high-rise buildings but also the design of new materials at micro scales.
Example - a perforated bridge design
The work shown here was part of a project for a proposed footbridge in Australia, for which Professor Mike Xie and his team were retained as the structural optimisation consultant by BKK Architects.
Example - stiffness design of wheel rims
With modern topology optimisation techniques, the design of high performance wheels can be achieved quickly. One of the wheel designs obtained from using the BESO technique is given below, with comparison to existing real wheels.
