| Summary: | Tensioned fabric structures (TFS) are structures that have flexible membranes and highly suited for construction areas to maintain the concept of sustainability development, the new form and complex TFS need to be found in order to generate continuity in the development of TFS. However, research study on a new form of half-Costa TFS model in YZ-plane with different, has not obtained attention from researchers over the world. The objectives of this study are to propose suitable boundary of half-Costa TFS model in YZ-plane and carry out its form-finding. This study also incorporates computational form-finding using nonlinear analysis method. The results of this study serve as a reference for proper selection of most suitable parameters to increase the performance of TFS by considering the factor of selecting suitable boundaries. In order to achieve the objectives of this study, proper computational analysis needs to be adopted such as the convergence curve theory that value obtained must be less than 0.01. The possible initial equilibrium shapes for half-Costa TFS models in YZ- plane are obtained thru form-finding analysis. Additionally, different boundaries and geometries of half-Costa in YZ-plane will provide an alternative form for design engineer and architects to adopt in the design of TFS. The outcomes of this study indirectly relate to the betterment in achieving the sustainability development and green building concept that is beneficial for future consideration. © 2016 Universiti Putra Malaysia.
