Abstract

Hinged connections are an often used type of connection between secondary and primary beam with flushed upper flanges. A very economic type of connection in terms of manufacturing and erection are long fin-plates. Unfortunately they are no fork bearing, therefore the usual formula for the elastic critical moment Mcr for beams cannot be used. To design a beam according to DIN EN 1993-1-1 it is necessary to know the actual stiffness of such connections to be able to consider it in the calculation of Mcr. This is also the case for other typical hinged connections like notched beams with either fin-plate or double angle connection. This problem of otherwise very economic connections is the reason for taking a closer look at their influence on the lateral-torsional buckling in the research project AiF-No. 16872 N at the Lehrstuhl für Metallbau (chair of metal structures) der Technischen Universität München. The following second part of the paper deals with the results of the parametric study, the substitute model to calculate Mcr and the additional aids for practical use (for part 1 of the paper see [9]).
