Experimental study on the shear strength of reinforced concrete composite T-shaped beams with web reinforcement

“…While interface shear strength has been widely studied in composite beams [6][7][8][9][10][11], their vertical shear strength has not been analysed in depth [4]. Experimental analyses of fullscale composite specimens with web reinforcement can be found in the literature [12][13][14][15][16][17][18][19][20], but they do not analyse either the contribution of slab to shear strength or the influence of the interface between concretes on shear strength. Current codes (like EC2 [21] and MC-10 [22]) do not clarify how to account for the slab in the shear strength of composite elements.…”

Analysis of the shear strength mechanism of slender precast concrete beams with cast-in-place slab and web reinforcement

“…In the scientific literature, several publications [14][15][16][17][18][19][20][21][22][23] are about the experimental analysis of full-scale concrete composite beams with web reinforcement. Most have focused on analysing the verification of these elements' shear capacity according to design code' formulations.…”
