A new computational technique in the finite element collapse analysis of framed structures, which is called' the adaptively shifted integration technique', is proposed and applied to the analysis of static and dynamic collapse behaviors of steel as well as concrete framed structures. In the present method, plastic hinges, cracking and fracture on an arbitrarily located cross-section in each finite element can be taken into account in a physically explicit and exact way by shifting the locations of numerical integration points in the element. The present technique can be easily implemented in the existing codes equipped with standard beam elements.
