Nonlinear Analysis And Behaviour Of Thin Concrete Axisymmeric Shells. This project concerns the highly complex behaviour of thin concrete shells and domes. These structures were in vogue in Australia in the 1970's because their construction is highly efficient, but their use ceased following several collapses. The reason was an inability at the time to predict their behaviour, which requires challenging theoretical methodologies and computer software. The project will develop sophisticated mathe ....Nonlinear Analysis And Behaviour Of Thin Concrete Axisymmeric Shells. This project concerns the highly complex behaviour of thin concrete shells and domes. These structures were in vogue in Australia in the 1970's because their construction is highly efficient, but their use ceased following several collapses. The reason was an inability at the time to predict their behaviour, which requires challenging theoretical methodologies and computer software. The project will develop sophisticated mathematical tools, that include concrete shrinkage, creep, cracking and thermal effects, to enable the design of safe concrete shells and domes, and it is underpinned by and builds on support awarded recently by the ARC to the investigators.Read moreRead less
Nonlinear Analysis and Behaviour of Shallow Concrete Arches. Concrete arches are widespread structural elements, but they are usually deep so that predicting their response is routine. The analysis of shallow arches is much more difficult, and with the contemporary use of higher strength concretes, shallow arches are often the optimum geometric configuration. This project aims to investigate the profoundly nonlinear behaviour of flat arches, which may be close to snap-through buckling, even unde ....Nonlinear Analysis and Behaviour of Shallow Concrete Arches. Concrete arches are widespread structural elements, but they are usually deep so that predicting their response is routine. The analysis of shallow arches is much more difficult, and with the contemporary use of higher strength concretes, shallow arches are often the optimum geometric configuration. This project aims to investigate the profoundly nonlinear behaviour of flat arches, which may be close to snap-through buckling, even under service load, due to creep and shrinkage. This research will fill an important gap in structural mechanics, and produce fundamental insights into the response of arches containing concrete. The outcomes will include much needed design guidance.Read moreRead less
