Outline of Final Research Achievements

For the purpose of developing a smart structural health monitoring system for super high-rise building, the story stiffness identification method using a shear-bending model was proposed to directly evaluate the story stiffnesses. The shear and bending model is useful to take into account the influence of bending deformation of high-rise buildings. In the statistical approach method, by supposing the floor rotation angle can be obtained as the additional measurement data, we proposed a new algorithm to correct the lowest mode shape of rotation angle. In this method, the probabilistic distribution of the lowest mode shape of floor rotation angle can be updated based on the conditional probability problem. By using the inverse-mode method for the shear-bending model, the bending stiffness can be identified stably from the updated the lowest-mode shape of floor rotation angle.
