[en] A research on a specific type of unstiffened extended end-plate joint used to connect I-shaped
beams to concrete-filled rectangular hollow section columns is presented in this paper. The main idea is to use long bolts throughout the column to connect the beam end-plates, so: (1) avoiding intermediate connecting elements (e.g. a reverse U channel) or special bolts (e.g. blind bolts) that are sometimes used in practice; (2) improving the resistance and stiffness of the joint to be used in seismic resistant frames. Firstly, a test program has been performed within a RFCS European project entitled HSS-SERF “High Strength Steel in Seismic Resistant Building Frames”, 2009-2013. In the test program, specimens subjected to significant bending moments (and shear) or to shear only have been defined. Then, analytical models based on the component approach and aimed at predicting the joint response have been proposed; their validity is demonstrated through comparisons with the test results. Finally, the requirements of EN-1998-1-1 related to full strength resistance for the proposed joint configuration are discussed, accounting for the actual position of plastic hinges and the
possible individual over-strength factors for each component.
