Abstract

Abstract Though every care is taken at the time of laying rails for the E.O.T. Crane travel, the track is usually found to be imperfect. These imperfect rail joints produce greater dynamic deflections in the E.O.T. Crane bridge girders. Earlier investigations mainly deal with simultaneous similar type of joints. Joints of the dissimilar type occuring simultaneously produce dynamic deflections of high magnitudes and need to be avoided. Considering the bridge girder as a beam of constant flexural rigidity, the effects of dissimilar type of joints occuring simultaneously are studied by considering them as support excitation functions acting on either side of the bridge girder.
