Abstract
Appropriate positions of plastic hinges can be evaluated by using the adaptively shifted integration (ASI) technique in the elastic-plastic analyses of framed structures. In this paper the ASI technique is applied to the degenerated Timoshenko beam element developed by Dvorkin et al., which is considering the effect of large displacements/rotations. By slightly modifying the shape functions of Dvorkin's element, the effect of large rotations can be precisely taken into account with the use of the ASI technique. Therefore, precise rigid body rotation about a plastic hinge can be represented by the presented element. Stresses at the hinge are also evaluated appropriately.
