| Research Abstract |
Monitoring the relative story displacement in real time makes it possible to identify the damaged elements. First, we developed lateral displacement sensor composed of a LED array, a lens with a fixed focal length, and a position sensitive detector (PSD). Next, we discussed the feasibility of the LDS implemented in an actual building. Finally, we developed and evaluated a novel five-degree-of-freedom (5-DOF) sensor system which can simultaneously measure the relative-story displacement, the local inclination angle, and the torsion angle was developed using three pairs of LED arrays and PSD units.
