Deflection Capacity of Slender Concrete-Filled Square Steel Tube Beam-Columns Under Monotonic Lateral Loading

Shear force‐deformation relationship of concrete‐filled square steel tube beam‐columns under monotonic lateral loading

“…Comparison of predicted and experimental shear force‐rotation angle relationships for specimens of Ref. [18] ( η = 1.08 (FA), s σ u = 457 N/mm 2 )…”

“…[14 and 15], and middle to slender beam‐column specimens with buckling length‐section depth ratios of λ = 10.0‐20.0 in Ref. [18] are shown in Figures 13‐16, respectively.…”

“…Also, the rotation angle ( e R m ) of the elastic part due to the bending moment in Figure 2C and the rotation angle (R s ) of the elastic shear deformation of the entire column length in Figure 2D are given by Equations (10) and (11), respectively. Table 1 summarizes the experimental data from previous researches [8][9][10][11][12][13][14][15][16][17][18] used to examine the shear strength and deformation at each point in the proposed model of the shear force-deformation relationship. The experimental data are the shear strength and deformation results of previous researches based on the monotonic loading and the first cycle of cyclic flexuralshear loading tests under a constant axial force using square CFT beam-column specimens.…”

Behavior of square concrete‐filled steel tubular beam‐columns subjected to lateral loads with constant cyclic displacement

“…Table 1 shows the monotonic loading specimens, which included fourteen CFT columns. 17 Table 2 shows the cyclic loading specimens, which included twenty-eight CFT specimens and six vacant steel tube specimens (Nos. [10][11][12][13][14][15].…”
