Mar 09, 2015 · A p = cross-sectional area of pile base, m 2. D = diameter of pile shaft, m. γ = effective unit weight of the soil at pile tip, kN/m 3. N γ = bearing capacity factor. N q = bearing capacity factor. Φ = Angle of internal friction at pile tip. P D = Effective overburden pressure at pile tip, in kN/m 2.

Apr 21, 2016 · Crane Tech teaches a 4 step process: Calculate the FORCE exerted on the ground (i.e. crane weight and attachments, plus load weight and rigging) Obtain the Ground Bearing Capacity (GBC) permitted for the soil you are set-up on. This is the PRESSURE the soil can withstand. Determine AREA by calculating FORCE ÷ PRESSURE.

Step 1. Look at the general instructions at the front of your project plans. Under the heading "Concrete" you will see a specific note of the pounds per square inch--psi--strength that the ncrete must reach. This note reflects the specific mix you will order throughout your project. Write this number down.

In this example, the light truck tire has a load index of 117/112. Using the Load Range Chart, the 117/112 load index equates a load capacity for a single tire of 2,833 pounds and a load capacity of 2,469 pounds for two tires. The reason the capacity for two tires is lower than a single tire is to make sure that the vehicle can ntinue to

The bearing capacity of your soil will help you determine if you need a shallow foundation or deep foundation. Soil strength directly under the footing, where loads are ncentrated, is crucial to foundation performance. You can get a pretty good idea of the soil bearing capacity in the trench bottom using a hand penetrometer.
