An experimental study to determine the optimum depth of steel anchors in RC subjected to shear force

An Experimental Study to Investigate Shear Performance of Anchor Bolt to Strengthen an RC Frame Against Lateral Load

“…Shear capacity of an anchor connected to the conjunction area of the RC frame with concrete strength fck=9.98 MPa and anchor bolt in diameter of 10 mm (Ø10) and 100 mm in anchor depth was found 15.75 kN for four bolts and 11.83 for two bolts. However, the shear capacity of one anchor connected to RC cubic samples with concrete strength fck=9.42 MPa gave 24.11 kN found by Odacioglu which is quite higher than the shear capacity of the anchors connected to the conjunction area of an RC frame (Odacioglu et al, 2022). In here, an RC cubic samples was being forced with only shear, but the conjunction area of the RC frame was forced with both shear and bending moment which is causing cracks in the conjunction area.…”

“…According to the tests the anchors are embedded in reinforced concrete in compression gave much more performance in comparison stress the anchors embedded in reinforced concrete under tension stress or no stress. The anchors used in the second group of tests where two of the specimens are in compressions and another two are in tension zone, gave quite reasonable performance in comparison to the results indicated in the tests carried out by Odacioglu et al (2022) where there is no tension or compression in the reinforced test specimens. As a result, the equation found by (2022) releated with the shear performance of anchors, is found quite preferable and reasonable as long as the anchors are embedded in a zone without tension stress of reinforced frame.…”

“…That is why in the second group of three tests C4, C5 and C6 another two anchors were additionally embedded in compression zone of the beam-column junction area. The anchors used in the second group of tests where two of the specimens are in compressions and another two are in tension zone, gave quite reasonable performance in comparison to the results indicated in the tests carried out by Odacioglu et al (2022) where there is no residual strain like tension or compression in the reinforced test specimens. According to the tests the anchors are embedded in reinforced concrete in compression gave much more performance in comparison stress the anchors embedded in reinforced concrete under tension stress or no stress.…”

“…As indicated in the tests carried out by Odacioglu et al (2022) used one anchor bolt in diameter of 10 mm (Ø10) with concrete strength fck=9.42 MPa, the linear equation for the values of T1S between 70 and 110 mm depths of anchor bolts is given in Eq. ( 6) ( Odacioglu et al, 2022) T1S= 0.0658 x hef + 17.531 (6)…”

Shear Strength of an Anchor Post-Installed into a Hardened Concrete Member

“…Another lack of balance in the literature that must be highlighted is that most of the papers about anchors present experimental research works [3,9,11,20,22,[24][25][26][27][28][31][32][33][34][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51], empirical formulations [4,10,13,14,20,26,33,40,44,45,[52][53][54][55][56][57], and numerical analyses [3,32,35,36,[58][59]…”
