Experimental and Numerical Investigation of IPE Reduced Beam Sections with Diagonal Web Stiffeners

Tahamouli Roudsari, M. / Jamshidi K, H. / Zangeneh, M. Mohebi

A reduced beam section (RBS) is a new type of connection in steel moment resistant frames. In addition to the major benefits, RBS has its own weaknesses, such as web local buckling and lateral torsional buckling. The purpose of this paper is to improve the performance of European I-beam profile (IPE) with an arched cut in the flange, using a diagonal stiffener of the beam web. With the help of laboratory tests and numerical models, it was found that the use of a diagonal stiffener in the area of an arched cut increased the energy dissipation and plastic rotation capacity of RBS connection.
