The data was generated assuming a 5/8" diameter bolt, d, with a bolt head diameter of 15/16" (1.5 time the bolt diameter), d h. From this data we can see there is a large variation in Q depending on the thickness of the joint relative to the bolt diameter and the joint diameter (i.e. how much material is being clamped) relative to the bolt ...

Example Calculation. Next, determine the capacity of 5/8 inch diameter bolts for loads traveling perpendicular to the grain of the wood. For simplicity, use table 11B of the National Design Specification. This is a table for single shear bolt capacities. This is conservative since the flitch beam being sized actually has bolts in double shear.
where A i is the bolt area and x i and y i are the x- and y- bolt locations, respectively.. It should be noted that this calculation is directly analogous to the calculation of the centroid of a cross section.. Bolt Pattern Moments of Inertia. The moments of inertia of a bolt pattern indicate the ability of the pattern to resist bending moments.
Anchor Bolt Testing: TMS 402 8.1.3.2.1 Anchors shall be tested in accordance with ASTM E 488 under stresses and conditions representing intended use, except that a minimum of five tests shall be performed.
For example, a 5/8-11 bolt with a 90,000 P.S.I. tensile requirement would normally use 1038 steel. If a minimum torque requirement of 105 ft-lbs is specified an increase to 1541 steel would be required. The hardness and matching of materials of both the bolt and nut are critical. Selection of washer material also

According to ASME B16.5, for flange classes 150# and 300# it's height should be 2 mm and for flange classes 600# and above, it should be 7 mm. Actualy, suppliers use 1,6 mm for 150# and 300# and 6,35 mm for 600# and above. The surface of the facing can be smooth or serrated, if it's serrated then it can be either concentric or spiral (I ...
An Example of Calculating Bolt Torque. For this example, our K will be 0.2 for a non-lubricated joint. Our bolt's diameter will be 0.5 inches, and the axial bolt force will be 11,175 lbs: T = 0.2 x 0.5 x 11,175. T = 1,117.5 inch lbs. Then, convert to foot pounds by dividing by 12: T = 1,117.5 / 12. T = 93.125 ft lbs

Calculate ASME B31.3 process piping bolt design load and design stress from temperature (ASME B31.3 Table A-2). Stress values are interpolated from the US data tables (US units govern). Bolt load is calculated from the design stress and the tensile area for either ANSI threads or ISO threads. For temperatures below the data range, the stress ...
at the grout-to-bolt interface, use the following calculation: F = BD x x L x 1600 psi Where: F = Bolt Pullout Force in lbs. D = Bolt Diameter in inches L = Length in inches of the bolt embedded in grout (does not include the portion of the bolt that is wrapped with tape or inside a bolt sleeve. = 3.1415

distributed only across those bolts among which it is located. For the example shown in Fig. 3 this means the total tension force is distributed across the upper four bolts. It is further assumed that the distribution of the operating force across these four bolts depends on its vertical distance from the total normal force application point.

Bolt forces at ULS Force/bolt due to vertical shear = 215/4 = 53.75 kN Force/bolt due to axial compression = 21.89/4 = 5.47 kN Force/bolt due to moment (considering top and bottom bolts only) = (96.38 + 17.2)/0.36 = 315.5 kN Thus, a single row is adequate. Considering the second line of bolts at a horizontal pitch of 100mm
Example J.4 Slip-Critical Connection with Short Slotted Holes High-strength bolts in slip-critical connections are permitted to be designed to prevent slip either as a serviceability limit state or as a strength limit state. The most common design case is design for slip as a serviceability limit state.
So, minimum preload in the bolt, Fp=10 KN. From eq.3, by applying Max. Permissible stress = safe stress for bolt = 650 Mpa, 650 = 10/(3.14*d*d) Or, d = 14.28 mm. So for this example we have to select M16 bolt. Apart from the bolt diameter calculation for tensile application, you also need to calculate thread engagement length for the bolt.
