PROBLEM TO BE SOLVED: To provide a technique for simulating breakage more precisely. SOLUTION: A structural analysis apparatus that can simulate breakage of a structure by using a model constituted of a plurality of elements is provided with: a state value calculation means for calculating a state value of each of the elements constituting the model; a breakage determination means for determining that the element is broken when the state value of the element satisfies a breakage threshold condition that is set in advance for the element: a crack face calculation means for obtaining a crack face of the breakage for the broken element that is determined to be broken by the breakage determination means; and a breakage threshold condition changing means for changing a breakage threshold condition that is set for the adjacent element, when there is an element that intersects with an extended face of the crack face of the broken element and that is adjacent to the broken element.
