Optimization of arch and archgrids against buckling
Confirmation seminar presented by Jinming Zhang
This research focuses on the development of the Hencky bar-chain model (HBM) for the elastic buckling analysis and optimization of arches and archgrids for maximum buckling capacity. Previous studies employing HBM predominantly addressed in-plane buckling problems involving funicular arches. This research extends the HBM application to any arch shape, loading and support conditions; including non-funicular arches and delves into their optimal designs against in-plane buckling and out-of-plane buckling. Additionally, the research aims to bridge the gap in current knowledge by formulating optimal design strategies for stability of archgrids, contributing significantly to the field of structural optimization design for this class of structures. The study developed a novel numerical method for easy analysis and optimization to achieve a better understanding of the buckling phenomena of arch structures.
