Abstract: A method for a large space structure collapse detection apparatus to detect collapse of a large space structure according to the present invention includes: measuring a change in external load with respect to at least one main member in the large structure; calculating a stress or stress sensitivity according to the measured change in the external load; and comparing at least one of the calculated stress or the calculated stress sensitivity with a predetermined collapse diagnosis reference value and determining a risk of collapse of the large space structure.
