Rock anchor design calculations
WebJan 7, 2024 · It is recommended in this commentary that the minimum required anchor capacity, derived from wall or other calculations, should be treated as the minimum ULS design resistance of the anchors. This design resistance must equal the characteristic resistance divided by the factor ym (Equation 8.4).
