“…Ruopp et al [28] did very extensive research concerned with the behaviour of large anchor plates under shear loading in steel-to-concrete joints and determined the load distribution of forces at the different rows of studs on the anchor plate. Luo et al [29] investigated steel plate-concrete joints connected with anchors and adhesive in terms of sheer performance and discovered that the ultimate loads of the anchor-and adhesive-connected specimens were approximately 78% of the sum of adhesive-connected and anchor-connected specimens.…”

The article presents the pull-out strength tests carried out on M10 expansion anchors in non-cracked and cracked concrete with a crack width cw = 0.30 mm. The breaking loads and the average pull-out strength of anchors in fibre-reinforced concrete substrates were determined. Fibre content ratios of 15, 30 and 50 kg/m3 were used. In addition, two different classes of concrete (C20/25 and C50/60) were tested. The addition of steel fibres caused a decrease in the pull-out strength by 5% for non-cracked concrete of C20/25 class and fibre content up to 30 kg/m3 and a further 7% for the remaining specified dosage. While for concrete of the C50/60 class, it a decrease in the pull-out strength of up to 20% was observed. For cracked concrete class C20/25 with crack initiation cw = 0.30 mm, the reduction was from 9% to 16% in relation to non-cracked concrete and a maximum of 18% for the fibre content of 50 kg/m3. The difference between the tensile load capacity of C50/60 class cracked and non-cracked concrete was lower than 5% and fell within the measurement error.

“…Ruopp et al [ 15 ] investigated large anchor plates under shear loading in steel–concrete connections. However, Luo et al [ 16 ] analyzed the connections of steel plates with concrete using anchors and adhesives in terms of shear performance. Woyciechowski et al [ 13 ] examined the load-bearing capacity of steel fixing anchors depending on the condition of the concrete substrate, which was degraded as a result of carbonation, water absorption, and freezing.…”

Pull-out strength tests conducted on screw anchors in uncracked concrete substrates of the C25/30 class are presented in this article. The destructive force for anchor–concrete fasting was tested, and in the next step, the average pull-out strengths of screw anchors in concrete substrates with and without the addition of steel fiber were determined. Currently, the pull-out strengths of anchors in fiber-reinforced concrete substrates are defined as for unreinforced concrete substrates. Therefore, pull-out tests were performed for screw anchors in fiber-reinforced concrete substrates. Fiber contents of 10, 20, 30, and 50 kg/m3 were used. An increase in the load capacity of screw anchors in a fiber-reinforced concrete substrate was demonstrated in a pull-out test compared to base samples without fibers. The coefficient related to the actual fastening behavior of a screw anchor in the fiber-reinforced concrete substrate was determined. It was assumed that a coefficient of 13.10 should be adopted. This was the lowest value obtained for the load capacity in this study for screw anchors in a fiber-reinforced concrete substrate.

“…So, the anchor webs welded between the double tubes would also play a better role in force transfer to reinforce the beam-to-CFDST column connection. Wang et al [12] tested existing reinforced concrete columns enhanced by web indirect bonding and web direct bonding combined with a steel end plate, and Luo and Wu [13] applied steel plate-concrete joints to strengthen the engineering structures, in which the steel plates and concrete were connected with anchors. The research results showed that the ultimate loads of the specimens using anchor steel plates improved a lot.…”

The haunched joint with ribbed anchor webs in the concrete-filled double steel tubular (CFDST) structure was proposed in this study. The CFDST column and the steel beam were connected by ribbed webs, which were anchored inside the column and connected to the beam web by the bolted connection, and haunches were welded to shift plastic hinges from the joint core to the beam end. The cyclic loading test was conducted on three beam-to-column joint specimens. Seismic behaviors, including failure modes, strain and stress responses, hysteretic curves, ductility, and energy dissipation capacity, were, respectively, analyzed. Besides, finite element (FE) modeling was validated and was used to further analyze the seismic behavior in consideration of connection constructional details, geometric dimensions, material strength, and axial compression ratios. The parametric investigation shows that besides ribs and haunches, stiffening diaphragms are practicable to connect the double tubes, especially for the high-strength steel beam; beam-to-column bending stiffness ratio per unit length is appropriate to be 0.3–0.5; choosing low strength grade of concrete is allowed to satisfy engineering requirements; the axial compression ratio should be limited within 0.5.
