Title: | Experimental Validation of Finite Element Models for Open-to-CHS Column Connections | Authors: | DAS, Rajarshi Kanyilmaz, Alper DEGEE, Herve |
Issue Date: | 2023 | Publisher: | MDPI | Source: | 2673-3951, 4 (4) , p. 454 -469 | Abstract: | The conventional ways to construct an open-to-circular hollow section (CHS) connection are either to directly weld the open section to the CHS column wall or to use local stiffeners (e.g., diaphragms) and gusset plates to connect the two structural components. These construction methods often subject the CHS to severe local distortions and/or require high welding quantities, hindering the real-life application of hollow sections. To overcome such difficulties, this study proposes two types of moment-resisting "passing-through" connection configurations, developed within the Eu-ropean research project "LASTEICON". These configurations consist of main beams connected to the CHS column via either an I-section or individual steel plates passing through the CHS column. The passing-through system is implemented using laser cut and weld technology and efficiently avoids excessive use of stiffening plates, local damages on the CHS wall and premature flange failures. The proposed configurations are investigated experimentally and numerically under two different load cases in order to characterize their structural behaviour. Finite element models have been developed and calibrated with respect to the experimental force-displacement behaviour of the connections as well as their observed failure modes. The efficiency, benefits, and limitations of the modelling approach were discussed through a detailed comparison study between the experimental and numerical results. | Keywords: | tubular structures;open-to-CHS-column connection;passing-through joints;hollow section joints;through-plate connections;through-beam connections | Document URI: | http://hdl.handle.net/1942/42077 | DOI: | 10.3390/modelling4040026 | Rights: | 2023 by the authors.
