This page details the methodology to resolve forces and moments applied to a bolt pattern into axial and shear loads acting on the individual bolted joints in the pattern.

As indicated in the RCSC Specification Commentary, there are two cases in which bolts and nuts must be treated as a manu-factured matched assembly: when bolts are galvanized (Com-mentary Section 2.3.3) and when “tension-control” bolts are specified (Commentary Sections 2.2 …

Two important steps to define bolt preload in simulations: load and lock. ‐ Load: Specify the tensile force developed in the bolt during its tightening. ‐ Lock: Simulates complete tightening of the bolt before applying any external loads on the assembly. Why is locking the bolts important?

Finding Forces on Bolts. Now that you know HOW a bolt transfers force, let's look at ways in which we can determine the force on a given bolt in a connection. The methods and procedures commonly used for finding forces resulting from applied forces are presented below.

Free and easy to use calculator for the analysis of numerous steel bolts, considering in-plane shear and moment loads. The ClearCalcs steel bolt group allows the user to analyze numerous steel bolts located at arbitrary X and Y positions in a few simple steps.

The direct forces in the X- and Y- directions, \(F_{c.x}\) and \(F_{c.y}\), respectively, are divided between the bolts according to the bolt stiffnesses. Because the bolts are all assumed to have the same material and length, the stiffness is dependent only on area.

Structural Central's Bolt Group Tool is structural engineering software that allows you to quickly generate the calculations required to analyze an eccentrically loaded bolt group used in a structural connection and design the bolts for the required strength.

A bolt pattern is arrangement of bolted joints, typically four or more, that connect two or more components together. This course details the methodology to resolve forces and moments applied to a bolt pattern into axial and shear loads acting on the individual bolted joints in the pattern.

bolt geometry that we used, longitudinal measurements would ac- tually reveal a component of the elastic stiffness tensor, and not E . Therefore, it was expedient to measure the shear modulus and use

Mechanical Fasteners (i.e. bolts, rivets, and pins) are most frequently used in structural steel connections where the load direction is perpendicular to the bolt axis as shown in Figure 4.2.1. In this situation the principle force in the bolt is shear.
