To thispurpose, twojointconfigurations aredesigned basedon acapacity-basedapproach, namely“partlyembedded”and “completely passing through” steel beam, and are examined through detailed FE analyses. A parametricstudy is carriedout to provide sufficient insight into the system interms of strength,stiffness and local bearingstrength, in view of validating the proposed design procedure | Keywords: | Steel and concrete hybrid connections;Embedment length;Energy dissipation;Seismic-resistant structures;Embedded steel sections | Document URI: | http://hdl.handle.net/1942/30692 | ISSN: | 2352-0124 | e-ISSN: | 2352-0124 | DOI: | 10.1016/j.istruc.2019.10.011 | ISI #: | WOS:000516825800011 | Rights: | 2019 Institution of Structural Engineers.
