説明

Gerber beam which is often used as a bridge has discontinuity conceming the slope and shearing force at hinge point and middle support. On the occasion of analyzing the stress, deformation, vibration or buckling of such structure as Gerber beam, solution becomes complex uselessly because of the discontilluity, and its numerical calculation becomes unstable. In this paper, the author shows the general method to analyze skillfully the structure with discontinuous elements and analyzes the buckling problem of Gerber beam. The buckling behaviour of Gerber beam groups into two classes by the difference of buckling parts of beam. It is showed that the positions of hinge and middle support act upon the buckling behaviour, and the domain of I and II-type buckling, the eigenvalue and buckling mode are calculated in addition.
