ABSTRACT

The restraining actions between adjacent segments in continuous beams are not easily predicted, because there are interactions between the segments at buckling, as indicated in Figure 10.1. These interactions affect the stiffnesses of the restraining segments, which depend not only on their geometric and material properties, but also on the relative importance of their loading. Because of this, the information given in Chapters 8 and 9 for elastically restrained beams and cantilevers cannot be used directly to predict the elastic buckling loads of continuous beams.
