Generalized method for identifying yield-line patterns in T-stubs using discontinuity layout optimization

Yield‐line Mechanisms of Endplate Connections with Eight Bolts and Circular Bolt Configurations Using DLO

“…Detailed information can be found in the already given literature. The here presented version of the DLO approach for calculating T-stubs in steel connections was verified on a wide range of experiments from the literature and with numerical and analytical examples [25,7]. Therefore, the presented DLO approach is suitable for solving the given problems.…”

“…The DLO was applied in [24] to obtain the limit loads of steel connections with a single bolt loaded in-plane. Afterwards, the method was extended to steel connections loaded out-of-plane in [25], which provides a generalized method for identifying any yield-line patterns in Tstubs. In [7], the method was further verified on a large range of experiments from the literature on bolted flange-plate connections in hollow section members.…”

Bemessungsvorschlag für geschraubte, polygonale Endplatten bei runden Hohlprofilen unter Zug

“…Die DLO-Methode kann auch zur Analyse gemauerter Strukturen [28][29][30][31] und von Stahlbetonplatten [32][33][34][35] eingesetzt werden. Die Anwendung auf Probleme des Stahlbaus erfolgte in [10,11,[36][37][38]. Zudem existieren bereits interessante Weiterentwicklungen zur Kombination von FEM und DLO, wie z.…”

“…Des Weiteren wird die äußere Arbeit über eine Nebenbedingung normiert, weshalb λ als linearer Laststeigerungsfaktor betrachtet werden kann. Die hier verwendete Variante der DLO-Methode wurde bereits in mehreren Literaturquellen ausführlich erläutert, weshalb an dieser Stelle auf die Quellen [10,11,37,38] verwiesen wird. Die DLO-Methode wird zu rein akademischen Zwecken verwendet.…”
