Deflection 5 8 18

broken image


Atkore pipe and conduit products are made from unplasticized polyvinyl chloride (PVC) compounds, which allow these products to flex without breaking. Consequently, Atkore pipe and conduit products can be purposely curved along their length a certain amount without adversely affecting their pressure-carrying or load-carrying ability.

Figure 1 Longitudinally Curved Pipe

Curving a pipe along its length is commonly referred to as longitudinal bending. See Figure 1 for an illustration of a pipe that has been longitudinally bent.

Proposed and experimental deflection methods include ion beam shepherds, focused solar energy and the use of mass drivers or solar sails. Initiating a nuclear explosive device above, on, or slightly beneath, the surface of a threatening NEO is a potential deflection option, with the optimal detonation height dependent upon the NEO's composition.

There are two important limitations to the longitudinal bending of Atkore products 1) the bending stresses that are induced in the pipe due to the bending, and 2) the axial deflection of gasketed pipe joints. These limitations are discussed below.

  2. The deflection calculator provides several engineering specifications such as the moment of inertia and yield strength to determine deflection. You also have options depending on the expected configuration of your solution: whether there will be one fixed end, two fixed ends or the load will be supported on both ends.

Bending Stresses

For a pipe of a given material, the stresses that are induced in the pipe when it is bent depend upon the radius of bending curvature and the diameter of the pipe. Smaller bending radii cause greater stresses in pipe walls. Also, larger diameter pipes will be stressed more than smaller diameter pipes for a given bending radius. Wall thickness is not a consideration for bending stresses.

The minimum Bending Radius (R), and maximum End Offset (Z), for each Atkore) product can be found in the tables on the back of this sheet. Longitudinal bending of Atkore products by mechanical means must be controlled to prevent excessive loading and/or damage to the pipe. In many cases, bending of PVC pipe can and should be accomplished manually. Pipes with large diameters and/or thick walls may be very difficult to properly bend, so fittings may be required to achieve directional changes in these cases.

Gasketed Joint Axial Deflection
Figure 2 Axial Deflection of Gasketed Joint

In the field, Atkore recommends a maximum of one degree of axial gasketed joint deflection. If greater curvature or joint deflection is desired than what is recommended, fittings should be used. There are many fittings for PVC pipe available for this purpose.

It is difficult to longitudinally bend gasketed pipe without causing axial deflection at the joints. For this reason, Atkore gasketed pipe joints must be restrained from excessive axial deflection if the pipe is to be longitudinally bent. It is sometimes possible to accomplish this by backfilling over the joint before bending the pipe body.

Use our online angle iron deflection calculator to calculate deflection for center load beam type by entering the modulus of elasticity of the iron(steel), load on beam, length of beam, moment of inertia of the L cross section of beam and choosing the support type as support or fixed at both ends.

Angle iron is a construction material constructed using a piece of structural iron or steel with the 'L' shaped cross section. It can be otherwise called as angle, angle bar, L bar, L beam. Use our online angle iron deflection calculator to calculate deflection for center load beam type by entering the modulus of elasticity of the iron(steel), load on beam, length of beam, moment of inertia of the L cross section of beam and choosing the support type as support or fixed at both ends.

Formula:

Support at both ends:d = (w × L3) / (48 × E × I)Fixed at both ends:d = (w × L3) / (192 × E × I)Where,d = Deflectionw = Load on BeamL= Length of BeamE = Modulus of Elasticity of the Iron(Steel)I = Moment of Inertia of the 'L' Cross Section of Beam

Example:

Calculate angle iron deflection of a beam fixed at both the ends with modulus of elasticity as 25 lb/inch2 for a load of 500 lb, length of 12 inch and moment of inertia of the L cross section of beam as 18 inch4.

Solution:
