The present study is concerned with the shifted integration technique in one-dimensional finite element analysis. The proposed technique is effective in the plastic collapse analysis of framed structures, in which the locations of plastic hinge formations can be controlled by the movement of numerical integration points. Some numerical studies are conducted for a simple beam in order to verify the validity of the technique. The shifted integration technique is also applied to the crush analysis of three-dimensional framed structures under quasi-static loading, which is based on the incremental theory by the updated Lagrangian Jaumann stress rate formulation employing the resultant forces and considering the strain hardening and the frictional contact. The calculated finite element solutions are compared with the crush test results.
