Elastic - plastic analysis of steel damper by using degenerated Timoshenko beam element based on the ASI technique

The finite beam element with the use of the adaptively shifted integration (ASI) technique is suitable for elastic-plastic analyses of framed structures, because a plastic hinge can be set at an appropriate position. In this paper the ASI technique is applied to a degenerated Timoshenko beam element that is generally used. The developed element is applied to the analyses of the steel damper for base isolation systems of large scale buildings (AU)
