- Abstract
- The report deals with the nonlinear analysis of eccentrically braced steel frames (EBFs) for cyclic static and dynamic loading conditions. Two analytical models are developed using a finite element stress resultant formulation for the purpose of performing static and dynamic nonlinear analyses. The first of these elements is intended to model links in EBFs. The second element is used to model composite floor beams outside the link, accounting for moment-axial force interaction and the cyclic effects of composite action in a practical manner. Three numerical examples are presented concerning the nonlinear static analysis of links and EBFs.
