The present invention relates to a method for analyzing the structure of a large-scale structure, the method comprising the steps of: entering input conditions to a plurality of structural members forming the framework of a large-scale structure to model the framework thereof by a program; entering loads sequentially applied to the structural members according to the construction sequences of the framework; and respectively calculating deformation and stress distribution cumulatively occurring in the structural members according to the construction sequences of the framework, wherein the step for respectively calculating deformation and stress distribution includes calculating deformation and stress distribution cumulatively generated by the loads in the case of a block defined by a section distant from each construction position of the framework as a predetermined distance, and calculating deformation and stress distribution respectively and proportionally by a load sharing ratio applied to each of the structural members in the case of structural members disposed further away than the block. According to the present invention, the cumulatively generated deformation and stress distribution can be calculated for only the structural members of the block, and the deformation and stress distribution can be calculated respectively and proportionally for the structural members disposed further away than the block by a load sharing ratio applied to each of the structural members, unlike conventional construction step analysis for respectively calculating and analyzing the deformation and stress distribution of the whole structural members in all the construction steps, thereby saving time and resources for structural analysis.
