Allowable Load for Drop Hammer Driven Piles Solution

STEP 0: Pre-Calculation Summary

Formula Used

Allowable Pile Load = (2*Hammer Weight*Height of Drop)/(Penetration per Blow+1)
P_a = (2*W_h*H_d)/(p+1)
This formula uses 4 Variables

Variables Used

Allowable Pile Load - (Measured in Kilogram) - Allowable Pile Load is the load allowed on a pile by considering it's bearable stress.
Hammer Weight - (Measured in Kilogram) - Hammer Weight is the simply the weight of the hammer.
Height of Drop - (Measured in Meter) - Height of Drop is the height from which hammer is dropped.
Penetration per Blow - (Measured in Meter) - Penetration per Blow is the measure of penetration of pile on each blow of hammer.

STEP 1: Convert Input(s) to Base Unit

Hammer Weight: 2.02 Kilogram --> 2.02 Kilogram No Conversion Required
Height of Drop: 3 Meter --> 3 Meter No Conversion Required
Penetration per Blow: 2 Millimeter --> 0.002 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_a = (2*W_h*H_d)/(p+1) --> (2*2.02*3)/(0.002+1)

Evaluating ... ...

P_a = 12.0958083832335

STEP 3: Convert Result to Output's Unit

12.0958083832335 Kilogram --> No Conversion Required

FINAL ANSWER

12.0958083832335 ≈ 12.09581 Kilogram <-- Allowable Pile Load

Weight of Hammer given Allowable Load for Steam Hammer Driven Piles

Go Hammer Weight = (Allowable Pile Load*(Penetration per Blow+0.1))/(2*Height of Drop)

Height of Drop given Allowable Load for Steam Hammer Driven Piles

Go Height of Drop = (Allowable Pile Load*(Penetration per Blow+0.1))/(2*Hammer Weight)

Weight of Hammer given Allowable Load for Drop Hammer Driven Piles

Go Hammer Weight = (Allowable Pile Load*(Penetration per Blow+1))/(2*Height of Drop)

Height of Drop given Allowable Load for Drop Hammer Driven Piles

Go Height of Drop = (Allowable Pile Load*(Penetration per Blow+1))/(2*Hammer Weight)

Allowable Load for Drop Hammer Driven Piles

Go Allowable Pile Load = (2*Hammer Weight*Height of Drop)/(Penetration per Blow+1)

Allowable Load for Drop Hammer Driven Piles Formula

Allowable Pile Load = (2*Hammer Weight*Height of Drop)/(Penetration per Blow+1)
P_a = (2*W_h*H_d)/(p+1)

What is Drop Hammer?

The drop hammer is the simplest and oldest type of impact hammer. A hammer with approximately the weight of the pile is raised a suitable height in a guide and released to strike the pile head.

How to Calculate Allowable Load for Drop Hammer Driven Piles?

Allowable Load for Drop Hammer Driven Piles calculator uses Allowable Pile Load = (2*Hammer Weight*Height of Drop)/(Penetration per Blow+1) to calculate the Allowable Pile Load, The Allowable Load for Drop Hammer Driven Piles is defined as a group of piles penetrating a soil stratum of good bearing characteristics and transferring their loads to the soil by point bearing on the ends of the piles, the total allowable load would be the sum of the individual allowable loads for each pile. Allowable Pile Load is denoted by P_a symbol.

How to calculate Allowable Load for Drop Hammer Driven Piles using this online calculator? To use this online calculator for Allowable Load for Drop Hammer Driven Piles, enter Hammer Weight (W_h), Height of Drop (H_d) & Penetration per Blow (p) and hit the calculate button. Here is how the Allowable Load for Drop Hammer Driven Piles calculation can be explained with given input values -> 12.03593 = (2*2.02*3)/(0.002+1).

FAQ

What is Allowable Load for Drop Hammer Driven Piles?

The Allowable Load for Drop Hammer Driven Piles is defined as a group of piles penetrating a soil stratum of good bearing characteristics and transferring their loads to the soil by point bearing on the ends of the piles, the total allowable load would be the sum of the individual allowable loads for each pile and is represented as P_a = (2*W_h*H_d)/(p+1) or Allowable Pile Load = (2*Hammer Weight*Height of Drop)/(Penetration per Blow+1). Hammer Weight is the simply the weight of the hammer, Height of Drop is the height from which hammer is dropped & Penetration per Blow is the measure of penetration of pile on each blow of hammer.

How to calculate Allowable Load for Drop Hammer Driven Piles?

The Allowable Load for Drop Hammer Driven Piles is defined as a group of piles penetrating a soil stratum of good bearing characteristics and transferring their loads to the soil by point bearing on the ends of the piles, the total allowable load would be the sum of the individual allowable loads for each pile is calculated using Allowable Pile Load = (2*Hammer Weight*Height of Drop)/(Penetration per Blow+1). To calculate Allowable Load for Drop Hammer Driven Piles, you need Hammer Weight (W_h), Height of Drop (H_d) & Penetration per Blow (p). With our tool, you need to enter the respective value for Hammer Weight, Height of Drop & Penetration per Blow and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
