Through-plate joints to elliptical and circular hollow sections

Experimental and numerical investigation of concrete-filled hot-finished and cold-formed steel elliptical tubular stub columns

“…There were some HF specimens with their values of SI being smaller than 1.0, as shown in Figs. [16][17][18][19]. These concrete-filled HF specimens (see Tables 9 and 13) possessed much larger values of De/tε 2 for their steel tubes (see Fig.…”

“…Figs. 16 and 17 present the relationships between the strength enhancement index (SI) and the infilled concrete strength for different values of the section aspect ratio (α) and different cross-section classes of steel tubes, respectively. As shown in Fig.…”

“…There have been an increasing number of studies on the performance of steel members with EHS in recent years. These studies covered a wide range of topics, including the cross-section capacities of stub columns [9], the behavior of beams under bending and combined bending and shear [10,11], the behavior of columns under pure compression and combined compression and uniaxial bending (about the major axis and minor axis, respectively) [12,13], welded connections [14,15] and gusset plate connections [16,17]. Furthermore, numerical and experimental investigations on concrete-filled steel EHSs were also conducted [18][19][20][21][22][23].…”

Characterization of moment resisting I-beam to circular hollow section column connections resorting to passing-through plates

“…This design equation was therefore incorporated in the CIDECT Design guides [9]. A preliminary experimental campaign was conducted by Willibald et al [22] and Zhao [23] to study the behaviour of longitudinal and transverse through plate-toelliptical hollow section (EHS) connections. These authors also compared different types of through connections with similar branch type connections and obtained almost 1.65-1.96 times greater connection capacity using the "passing-through" approach.…”

Tension Strength Prediction of Transverse Branch Plate-to-Rectangular Joint with Concrete Filling

“…Recently, concrete-filled chord has been a prevailed technical practice in the tubular structure [9][10][11]. Besides concrete-filled circular section joint, elliptical section joint were also investigated about its structural performance [12][13]. Transverse and longitudinal BPRH joints with concrete-filling and other reinforcements' configurations are summarized in Tab.…”
