Abstract：The optimal prestress is the core and key problem of the design of string-supported dome.There is no unified design method of prestressing force for the current suspen-dome structure.Based on the four prestress design criteria,this paper summarizes the methods to determine the prestress of various suspender dome structures.In particular,the methods and steps of setting the prestressed force of large-span spacer cable and elliptical suspen-dome are described.The advantages and disadvantages of each method and the applicability of the method are discussed.The optimal prestress design of suspender dome is put forward:the lower strut layout optimization and the prestress value optimization two levels must be considered,which can provide reference for practical engineering prestress design.
