Abstract: A load calculator includes a coefficient storage, a replacement deriver, and an internal-load deriver. The storage stores a first coefficient, an internal load acting on a target point in a target member when a unit load acts on a concentrated load point in the target member along one of three orthogonal axes, and as a second coefficient, an internal load acting on the target point when a unit moment acts on the concentrated load point around one of the axes. The replacement deriver derives a replacement load and moment by replacing an external load acting on the target member with six force components acting on the concentrated load point. The internal load deriver derives an internal load acting on any target point with the first coefficient, the replacement load, the second coefficient, and the replacement moment when the external load acts on the target member.

Abstract: According to one implementation, a structural health monitoring system includes an ultrasonic transducer, an ultrasonic sensor, a strain sensor and a signal processing part. The ultrasonic transducer oscillates an ultrasonic wave to the first inspection area. The ultrasonic sensor detects a waveform of at least one of a transmission wave of the ultrasonic wave and a reflected wave of the ultrasonic wave. The transmission wave has transmitted the first inspection area. The reflected wave has been reflected in the first inspection area. The strain sensor detects a strain amount of the second inspection area. The signal processing part obtains at least one index, representing health of the structural object including the first inspection area and the second inspection area, based on the waveform detected by the ultrasonic sensor and the strain amount detected by the strain sensor.
