摘要: 裁剪分析是张拉膜结构分析的重要环节‚收缩补偿值是裁剪分析的一个极其重 要的参数‚涉及到结构的安全与经济.本文探讨初应力、荷载和徐变等因素对收缩补偿值 的影响‚给出收缩补偿值取值的建议‚并分析收缩补偿值对结构内力的影响.

关键词: 膜结构, 裁剪分析, 收缩补偿值

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. 

Key words:  membrane structure, cutting, shrinkage compensation
