PROBLEM TO BE SOLVED: To perform breakage generating prediction of high accuracy and high versatility. SOLUTION: This structural analysis apparatus performs numerical analysis of a structure including breakage using a finite element method of virtually dividing the structure into a plurality of elements and calculating change in each element. This structure analyzer includes a breaking strain storing means 4 for storing the breaking strain in each element in association with the stress three-axis degree of the element and the size of the element, a breakage determining means 6 for determining the breakage in each element based on the breaking strain stored in the breaking strain storing means 4, and a calculating means 8 for calculating the change in each element based on a change condition different depending on the determination result of the breakage determining means 6.
