Connection Design Calculator
Calculate the shear capacity of bolted steel connections based on bolt size, grade, quantity, and number of shear planes.
How to Use the Connection Design Calculator
- Enter the bolt diameter in mm.
- Select the bolt grade.
- Enter the number of bolts.
- Select the number of shear planes and click Calculate.
Casos de Uso
- •Designing bolted beam-to-column connections.
- •Checking capacity of existing bolted connections.
- •Comparing bolt sizes and grades for connections.
- •Structural engineering design documentation.
Fórmula
Bolt capacity = Fv × Ab × n_planes. Total capacity = Bolt capacity × n_bolts.
Preguntas Frecuentes
What is bolt grade 8.8?
Grade 8.8 bolts have a nominal ultimate tensile strength of 800 MPa and a yield strength of 640 MPa.
What is double shear?
Double shear occurs when the bolt passes through three connected plates, effectively doubling the shear area and capacity.
