A serious earthquake was occured in Japan on March 11, 2011 and some escalators fell off to downstair. A story drift make an installed length of a escalator fluctuate. Because of the forced displacement, the escalator-truss may catch the fatal damage. Therefore we carried out strength analysis (elasto-plastic analysis) of the escalator-truss. An Upper support angle is complete constraint condition, and lower support angle is taken forced desplacement. The maximum displacement is 200mm. Because the escalator-truss has horizontal reaction force when it is had forced displacement, we judged the frame to be able to become independent. A original-sized model displacement examination was compared with this calculation effect, we got similar force-displacement curve. We established strength evaluation means of the escalator-truss for the seismic design.
