| Abstract: | Cutting is an important step in the analysis of tensioned membrane structure and shrinkage compensation constitutes a very important parameter in cutting analysis, which affects the safety and economy of a project. In this paper the effects of load, prestress and creep on the shrinkage compensation are studied. Some suggestions are given for the determination of shrinkage compensation in engineering practice. Its effect on the interior force of the structure is also discussed. |
