Design aid SHEAR 2 consists of 3 tables that may be used to determine shear capacity for rectangular sections of width b or bw from 10 in to 32 in and thickness h from 10 in to 48 in. The failure will occur at the root of the nut threads. Req'd: (a) The Maximum Average Bearing Stress in the bolt. See the above two figures (Fig.1 and Fig.2) and design the cast in place anchor bolts according to the arrangement shown. Because the bolt is in single shear and threads are excluded from the shear plane, the shear stress on the bolt is simply given as in Eq. Caution. Fasteners - Bolts, nuts and threaded rods - torque, tension and loads; Related Documents . The shear force only becomes relevant when the bolts are not torqued. V = shear force on the bolt, in kN; and Vob = maximum permissible shear force on the bolt, in kN. Shear loads and tensile loads are the primary forces acting on a threaded fastener. Now, a bolt group might have less shear capacity than that due to other factors. !is~SmZf/q|J63dUahBL@/\ 7|s#_L_cy0liH&36$[`-A@,F These forces are computed using the mechanics principles discussed in Sections 4.3..

From the table at right, for a strength class of 10.9 and a maximum allowable load of 200 kgf, the suitable bolt is a 318[kgf]M8. Fn = Nominal shear strength, Fv = 0.50 Fu for bolts when threads are excluded from shear planes, i.e. nThe shear areas are: Zhenhai Guo, in Principles of Reinforced Concrete, 2014. To take full advantage of strength properties the shank of the bolt body should be within the shear planes. square base plate, subject to a factored axial dead load of 22.5 kips, factored live load of 65 kips, and a factored shear - In most bolted connection, the bolts are subjected to shear. To determine the average shearing stress in each plane, free-body diagrams of bolt L and of the portion of the bolt located between the two planes is drawn. When no shear strength is given for common carbon steels with hardness up to 40 HRC, 60 % of the ultimate tensile strength of the bolt is typically used as acceptable shear strength. Hence the bolt shank has a larger shear capacity. 5 An axial load bar becoming longer when in tension and shorter when A bolt commonly shears where its head meets the threads. For the shear margin of safety, simply swap out tensile and axial for shear. n s = number of shear planes intercepting non-threaded portion of shank = 1, for a bolt in double shear = 0, for a bolt in single shear. American Iron and Steel Institute. scenario, the bolt threads will shear out the nut threads. Again, citing Equation 1 and modifying it for the overlap of projected breakout area, Apt for each anchor bolt is found to be 90.99 in. (578.03 cm).
