The prestress affects the shape and mechanical property of the membrane structure.In general,the process of shape-finding can't simulate the process of construction.In this paper,a new shape-finding method has been offered to solve this problem.During the shape-finding process,the stress of any point in the structure during the construction can be attained.This process can also determine the construction method and give some guidance during the construction process.At the same time the error of the distribution of the prestress field caused by the construction can be given.
