Architectural Design Based on Structural Performance


图片



Innovative and efficient designs of structures can be achieved by applying optimisation techniques that are capable of minimising the material usage and maximising the performance. The bi-directional evolutionary structural optimisation (BESO) method, originally proposed by Professor Mike Xie and his co-workers, has been well developed for this purpose. BESO is based on the simple concept of gradually removing inefficient material from a structure and, at the same time, adding material to the most needed locations. Such a simple but universally applicable technique can be used to not only reduce the weight and the associated energy consumption of aircraft and motor vehicles but also produce strikingly elegant structural designs of bridges and buildings. This presentation will demonstrate how the BESO method (and the Ameba software developed by Professor Xie’s team) could be effectively used to design a wide range of high-performance and light-weight structures including spectacular buildings, long-span bridges, unmanned aircraft, exquisite furniture, and so on. The talk will also show how such beautiful and organic designs can be realised by using advanced manufacturing technologies including 3D printing.

Mike Xie is an Australian Laureate Fellow and a Distinguished Professor of RMIT University where he directs the Centre for Innovative Structures and Materials. He received his bachelor’s degree in engineering mechanics from Shanghai Jiao Tong University in 1984 and earned his PhD in computational mechanics from Swansea University in the United Kingdom in 1991. He was elected a Fellow of the Australian Academy of Technology and Engineering in 2011. His research impact in the field of structural optimisation was recognised by the 2017 Clunies Ross Innovation Award and the 2017 AGM Michell Medal. In 2019, he was appointed a Member of the Order of Australia (AM), for “significant service to higher education, and to civil engineering”. In 2020, he was awarded the Victoria Prize for Science and Innovation. In 2022, he was named the Sir John Holland Civil Engineer of the Year. Professor Xie is one of the most influential scholars in his field, with more than 500 publications and over 27,500 citations.
