Abstract

Form-finding analysis is carried out and presentedfor half-Costa tensioned membrane structure model inYZ-plane. There are three models presented, each withdifferent center part of the half-Costa boundaries. Nonlinearanalysis method is adopted for the form-finding analysis.Half-Costa tensioned membrane models in YZ-plane withdifferent geometry have been found in a good agreement withleast square error of total warp and fill stress deviation. Resultsobtained from this study would become a reference to selectsuitable parameters to increase the performance of sustainabletensioned membrane structure in the form of half-Costa inYZ-plane respected to their boundary condition. Theseresource efficient structures have the ability to prevent furtherdamage to the environment hence these models presented aregood selective forms for design engineer and architect to ponderon.
