Forces on bolted connections
The spreadsheet calculates the forces on the bolts in a bolted connection inserting the coordinates of each bolt composing the joint.
The considered external loads are: shear and tension forces, bending and torque moments.
It calculates the center of the connection with inertia characteristics and, taking into account the eccentricity of the point of forces application, calculates the bolts shear force along each axis and the tension.
Assigning the bending axis position it allows to evaluate the bending tensions on the bolts.
The results are shown in a graphical format enhancing the bolts in tension and compression.
Summary an detailed tables are included with summaries of all the reactions on each bolt:
- Total shear reactions on each bolt along X-Y axes
- Resultant shear on the bolts
- Resultant tension on the bolt
- Shear reactions due to the derived torque moment of applied shears Vx,Sd and Vy,Sd
- Shear reactions due to the design torque moment
- Shear reactions due to the design shear forces Vx,Sd and Vy,Sd
- Tension reaction on each bolt due to the design bending moment
A number of 100 bolts maximum can be represented.
Different worksheets are available:
- General bolted configuration assigning the coordinate of each bolt
- Specific sheet with bolts configuration disposed along a circle, useful for circular flanged connection
- General calculation of the neutral bending axis of the bolting with relevant calculation of forces on bolts and compressed contact area of the connection flange
Visual information are presented in a graphical format for shear and tension.
Shear vectors distribution for each bolt is shown giving the possibility to select one single bolt to show the forces acting on, with an easy identification of its position on the bolting.
The obtained values of the force on bolts can be used to verify the bolted joint by means of the other specific spreadsheet (see dimensioning of bolt spreadsheet in the connection category).
The spreadsheet you will purchase and receive is an excel file compiled in a “.EXE” application file format identified by our icon image. See the Activation/Support page for more details.
