In this research, we developed a mechanical loads measurement system for the stairs handrail during walking up. This system is composed of the handrail part including sensors and 3 steps stairs. The handrail material is midair SUS304, and has 2 strain gauges installed on it. and the height of the riser and length of the tread were based on standard dimensions for public facilities. The 3-axis force sensor is installed between the handrail and pillars using jigs for measuring mechanical loads perpendicular to the handrail. Using this system, 5 healthy adults participated in the experiment by walking upstairs. As a result, the total affecting time of the mechanical load against the handrail is about 1.396 s, normalized maximum load is about 0.036 N/N. Also, the mechanical waveforms graphs showed different behaviors,: Two participants' waveforms are positive at all phases, but one participant showed positive and negative phases, which means that both pushing and pulling action were performed.
