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.
Claims21
A method for a large space structure collapse detection apparatus to detect collapse of a large space structure, comprising:
- 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.
A large space structure collapse detection apparatus comprising:
- a measurement unit that measures a change in external load with respect to at least one main member of a large space structure;
- and
- a control unit that calculates stress or stress sensitivity according to the measured external load change, and determines a risk of collapse of the large space structure by comparing at least one of the stress or the stress sensitivity with a predetermined collapse diagnosis reference value.
A method for a structure monitoring apparatus to monitor safety of a structure by measuring vibration of the structure, comprising:
- setting measurement cycles of a plurality of sensors disposed in the structure;
- simultaneously measuring a change in external load of the structure using at least two of the plurality of sensors according to the predetermined measurement cycles;
- and
- calculating strain of the structure by simultaneously analyzing measured signals and forming a time-based strain variation chart.
