摘要：	Membrane fabric structures are spatial structures that allow for long span and lightweight roofs. In many cases, membrane roofs are supported with trusses or masts and prestressed together with cables to obtain a resistant shape for a given loading condition. For the design of membrane structures, geometrically nonlinear analysis is required. Additionally, modeling of each membrane element and formfinding of the shape are of great importance in the design process. First, an equilibrium-finding analysis is conducted for the purpose of obtaining the optimal shape of the membrane structure, during which the initial stresses of the membrane and cables must be balanced. Next, the stress-deformation analysis is performed for the required loading condition. This analysis allows understanding of the behavior of the structure and confirms that the design of the membrane satisfies the required safety factor for the construction. The analyses of the Southwestern Baseball Dome in Seoul and the Jeju Stadium Dome in Jeju Island, both in Korea, are presented, with an emphasis on details in all aspects of the analysis process. It is found that the selection of analysis and design techniques and appropriate construction materials would be most critical. The analysis results also show that the form-finding step has a significant effect on increasing the stiffness of the structure and a more regular geometry promotes a more stable response under various loading conditions.
