Low-cycle fatigue cyclic and psd testing of a two storey moment resisting steel frame with beam-to-column welded connections
The experimental campaign carried out at the European Laboratory for Structural Assessment of the Joint Research Centre at Ispra in a two-storey steel frame is presented d herein. The experimental activity is part of the Environmental and Climate SteelQuake project, for the assessment of low-cycle fatigue behaviour of steel beam-to-column welded connections of beams non-composite with the slab in location of the plastic hinges. The description of the mock-up, the testing apparatus and the relative instrumentation for measuring displacements, forces and deformations is presented. Pseudodynamic and cyclic tests were performed and the corresponding results are presented at the structure and connection levels in terms of the absolute and accumulated plastic ductility's in relation to the failure events of the welded connections. The importance of the panel zone in contributing towards the total rotation of the connection is highlighted.
