What is factor of safety?

A factor of safety, also known as safety factor, expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.

How to Calculate Allowable Load when Safety Factors are Given?

Allowable Load when Safety Factors are Given calculator uses Allowable Load=(Shaft Resistance/Factor of Safety F1)+(Toe Resistance/Factor of Safety F2) to calculate the Allowable Load, The Allowable Load when Safety Factors are Given formula is defined as the maximum working load which can be applied on the pile. Allowable Load and is denoted by Q a symbol.

FAQ

What is Allowable Load when Safety Factors are Given?
The Allowable Load when Safety Factors are Given formula is defined as the maximum working load which can be applied on the pile and is represented as Q a=(Q su/F1)+(Q bu/F2) or Allowable Load=(Shaft Resistance/Factor of Safety F1)+(Toe Resistance/Factor of Safety F2). Shaft Resistance is the load resisted by a pile's shaft, Factor of Safety F1 expresses how much stronger a system is than it needs to be for an intended load, Toe Resistance is the load resisted by the toe of a pile and Factor of Safety F2 expresses how much stronger a system is than it needs to be for an intended load.
How to calculate Allowable Load when Safety Factors are Given?
The Allowable Load when Safety Factors are Given formula is defined as the maximum working load which can be applied on the pile is calculated using Allowable Load=(Shaft Resistance/Factor of Safety F1)+(Toe Resistance/Factor of Safety F2). To calculate Allowable Load when Safety Factors are Given, you need Shaft Resistance (Q su), Factor of Safety F1 (F1), Toe Resistance (Q bu) and Factor of Safety F2 (F2). With our tool, you need to enter the respective value for Shaft Resistance, Factor of Safety F1, Toe Resistance and Factor of Safety F2 and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Allowable Load?
In this formula, Allowable Load uses Shaft Resistance, Factor of Safety F1, Toe Resistance and Factor of Safety F2. We can use 3 other way(s) to calculate the same, which is/are as follows -
  • Allowable Load=(Shaft Resistance+Toe Resistance)/Factor of Safety
  • Allowable Load=Gross area of column*(0.25*Compressive strength+Allowable stress in vertical reinforcement*Area ratio of cross sectional area to gross area)
  • Allowable Load=(Yield Strength*Cross sectional area/Factor of safety)/(1+0.25*sec((0.375*pi/180)/Least Radius of Gyration*Length of column*sqrt(Factor of safety*Allowable Load/Modulus Of Elasticity*Cross sectional area)))
