The main topic of this study is a damage factor estimation of crane-hooks. Our estimation is to recognize the tendency of the load condition. We examine the relation between the load condition and its deformation by numerical analysis based on FEM. The relation is recorded into the database. The feature points are detected from the crane-hook images where these points are defined in order to correspond to the numerical analysis results in the database. These points are compared to the relation that the database has. A data is defined as the force that minimizes the difference between the feature points of the image and the deformed nodal position of the database. Using Bayesian theory, we estimate the distribution of the load condition in case of that the crane-hooks are damaged. We find out some knowledge about the crane-hooks from the estimation result. These are as follows: the load condition lies between the most downward point and the tip-end point, the direction is toward the gravity direction.

This paper presents an estimation of the elastic shear buckling capacity of corrugated plates with edges elastically restrained against rotation. The corrugated plate possesses higher shear buckling capacity compared to an unfolded flat plate. It has been used to replace the concrete web in PC box girders in recent bridge constructions in Japan. In this study, the corrugated plate is modelled as an orthotropic Mindlin plate. Elastically rotational restraint on boundary edges is taken into account in the form of rotational springs in the analysis. The prediction of buckling capacities of corrugated plates is carried out by using the Rayleigh–Ritz method, which was proved to be consistent with those as predicted by existing formulas for the limiting cases of simply-supported and clamped edges. The present study covers the more general case of elastically rotational restraint on the boundary edges showing transition curve of plate buckling capacities from the case of simple support to the case of clamped support.
