【Abstract】 Hualian Ground Track Field Stand consists of an arch truss of 155m span,29 7m×93 12m reticulated shell,and support space frames and cover membrane.The structural form is fairly novel,but structural analysis and design are rather complicated.The structural analyses includes the form finding analysis,loading analysis and cutting and patterning of cover membrane,reticulated shell and arched truss analysis.This paper presents the analytical models,numerical procedures and results in detail.Meantime,the key joints,membrane manufacture and setting up procedure,also the manufacturing and erecting of the space trusses are presented concisely.更多还原
