WebDec 6, 2024 · The anchor bolt with thread height of 2.0 mm is taken as an example in the discussion below. Because the axial bearing capacity of the anchor rod with a thread height of 2.0 mm is 233 kN, the shear stress distribution of the anchor rod body and the nut under the axial force of 250 kN under different screw pitches was analysed. WebFRP Anchors High-strength FRP anchors are field-laminated and used to carry load into the concrete to effectively improve bond strength, or through the concrete to transfer load for increased capacity. CSS-CA and CSS-GA are carbon and E-glass fiber-reinforced …
