摘要

The present test summaries present the experimental research carried out at the "Politehnica" University of Timisoara, Romania, with the scope of investigating the influence of different column web stiffening solutions on the performance of beam-to-column joints of moment-resisting steel frames. The response parameters, such as resistance, rigidity, and ductility have been monitored. Five different types of panel web stiffening are compared in regard to a reference test. A quasilinear relationship between the moment capacity and the total shear area of the web panel resulted from the experimental tests. The initial rigidity has increased nonproportionally with the same parameter. The investigation of the failure modes proved that fragile failures have been obtained for the specimens with web reinforcement.
