Abstract
AbstractMembrane 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 form-finding 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 D...
