AbstractThis paper addresses key design considerations for single-layer mesh shell structures in public service projects in Jiaxing City，Zhejiang Province，encompassing mesh and component selection，extraction and division of structural benchmark surfaces，support configuration，primary load determination，structural stress analysis，and node design.The results demonstrate that a rationally designed single-layer steel mesh shell structure can support heavier roof ceramic panel systems with reduced member dimensions.Utilizing the Grasshopper component in Rhino software enables precise control of model data.Through analysis and statistical calculation of internal forces，diverse support forms are implemented to optimize support costs.By integrating spatial geometry and building functions，structural componentsand columns are strategically arranged to enhance grid shell stability.The computational process incorporates wind load data from wind tunnel tests and temperature stress effects.Design values are derived by enveloping results from combined and individual modeling analyses，with stress ratios，displacements，stability，and node strength allsatisfying code requirements.
