Calculating the Design Strength of a Connection Involving a Tension Member, Channel Member, and Gusset Plate
What is the governing design strength of the connection?
Is the design strength of the connection limited by bolt shear failure, bearing failure in the channel member, or bearing failure in the gusset plate?
Design Strength Calculation:
The design strength of the connection is limited by bearing failure in the channel member. The calculations show that 11 bolts are required to resist the tensile force on the member in this case.
Calculating the design strength of a connection involving a tension member, channel member, and gusset plate requires consideration of various failure modes. In this case, the design strength is limited by bearing failure in the channel member.
The calculations take into account the nominal strengths of the bolts and the bearing strengths of the channel member and gusset plate. The governing strength is determined as the minimum of these values.
Based on the calculations, it is determined that 11 bolts are needed to resist the tensile force on the member when bearing failure in the channel member governs. This means that the design strength of the connection is 312.4 kips.
All the edge distance and spacing requirements are satisfied in this scenario. The calculations consider the inclusion of threads in the shear plane and use a hole diameter of 11/16 inches.
