What is the minimum and maximum value of spacing between the bolts?

AISC Specification J3. 5 indicates that the maximum edge distance for bolt holes is 12 times the thickness of the connected part (but not more than 6 in.). The maximum spacing for bolt holes is 24 times the thickness of the thinner part (but not more than 12 in.).

What is the minimum bolt spacing?

Minimum pitch (distance between centres of bolt holes) shall not be less than 2.5 times the nominal bolt diameter.

What is the minimum allowable bolt spacing per AISC?

The minimum spacing between bolts and distance to the bolt centre to an edge of a connected part are checked. The minimum spacing 2.66 times (editable in Code setup) the nominal bolt diameter between centres of bolts is checked according to AISC 360-16 – J.

What is the maximum spacing of bolts if the connection is not subjected to corrosion?

The maximum spacing for bolts between painted members or unpainted members not subject to corrosion is 24 times the thickness of the thinner part (but not more than 12 in.).

What is the minimum value of end distance?

Explanation: Minimum edge distance and end distance from centre of any hole to nearest edge of plate shall not be (i) less than 1.7 x hole diameter, in case of sheared or hand flame cut edge, (ii) less than 1.5 x hole diameter, in case of rolled, machine flame cut.

What is the maximum distance between bolts?

AISC Specification J3. 5 indicates that the maximum edge distance for bolt holes is 12 times the thickness of the connected part (but not more than 6 in.). The maximum spacing for bolt holes is 24 times the thickness of the thinner part (but not more than 12 in.).

How do you calculate bolt spacing?

For example: The length of a workpiece is 48″ and you decide to install five screws as fasteners. The formula is: 5 + 1 = 6. Dividing this total into the 48″ length, means the five screws should be spaced every 8 inches – at 8″, 16″, 24″, 32″ and 40″.

What is edge and end distance?

3.Edge distance (e) : It is the distance of center of bolt hole from the adjacent edge of plate. 4.End distance (e’) : It is the distance of the nearest bolt hole from the end from the end of the plate.

What is end distance of bolt?

End distance (e1), i.e., the distance measured in the line of force from the center of the bolt hole to the nearest edge of an adjacent hole or to the end of the plate [11], has effects on the ultimate strength and failure mode of a bolted connection subjected to tensile loading.

How do you find the minimum edge distance of a bolt?

2. Minimum end and edge distance

  1. emin = 1.5 × diameter of the bolt hole ……. ( for machine cut element)
  2. emin = 1.7 × diameter of the bolt hole ……. ( for hand-cut element)

What is the edge distance?

Edge distance is a term used in sheet metal aircraft construction. It refers to the distance from the center of a rivet to the edge of the material it is holding together. … When two riveted parts are pulled apart, we have two forces at work.

Do bolts fail in shear or tension?

Bolts can fail in shear or in tension. Simple connection: If the line of action of the force acting on the connection passes through the center of gravity of the connection, then each bolt can be assumed to resist an equal share of the load.

What is bearing failure of bolt?

If the plate material is weaker than the bolt material, then failure will occur by bearing of the bolt on the plate and the hole will elongate. … Bearing failure. If the connected plates are made of high strength steel then failure of bolt can take place by bearing of the plates on the bolts.

What is maximum pitch distance?

Explanation: Pitch shall not be more than 16t or 200mm, whichever is less in tension member where t is thickness of thinner plate. Pitch shall not be more than 12t or 200mm, whichever is less in compression member, where t is thickness of thinner plate.
