Abstract
Cutting patterns of a simple form of a tent, so called 'Chinese hat', were analyzed in the paper. Stress distributions in prestressed membrane structures, according to cutting patterns prepared by the help of various numerical methods, were compared. A recently developed computer program, based on the dynamic relaxation method was used for the numerical analysis. The close connection between the shrinking of the cutting pattern and the stressing process of the tent was shown. Shrinking of the cutting pattern means that the stress free size of the tent is smaller than the boundaries of the theoretical shape, the tent structure achieves its shape and prestress during stressing on the original edges. The shrinking can be uniform or proportional to the stresses in the theoretical shape. The cutting pattern prepared without shrinking, produces tent surface that fits to the original boundaries without any strain and stress. To get prestress in the structure, the boundary conditions have to be changed. Cutting patterns prepared by the help of different methods and based on various models, without shrinking and with different shrinking, were analyzed. After the short demonstration of the different methods, the stresses in warp and weft directions were compared in the different construction shapes.
