Abstract

This paper introduces an innovative structural solution for dissipative zones of moment-resisting steel frames and eccentrically braced frames. High local ductility and high performance are intended to be achieved by the application of longitudinally multi-stiffened girder elements. Monotonic and cyclic test series are completed to analyse the influence of different stiffener configurations on the cyclic strength and cyclic ductility of the girder. Based on the experimental results, practical conclusions are drawn on the preferable configuration. The test results further provide solid base for the numerical model development.
