Basic Development Length for 18mm Diameter Bars Solution

STEP 0: Pre-Calculation Summary

Formula Used

Development Length = (0.125*Yield Strength of Steel)/sqrt(28 Day Compressive Strength of Concrete)
Ld = (0.125*fy_steel)/sqrt(f_c)
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Development Length - (Measured in Millimeter) - Development Length is the amount of reinforcement or bar length needed to be embedded into the column to establish the desired bond strength between the concrete and steel.
Yield Strength of Steel - (Measured in Megapascal) - Yield Strength of Steel is the level of stress that corresponds to the yield point.
28 Day Compressive Strength of Concrete - (Measured in Megapascal) - 28 Day Compressive Strength of Concrete is defined as the strength of the concrete after 28 days of using it.

STEP 1: Convert Input(s) to Base Unit

Yield Strength of Steel: 250 Megapascal --> 250 Megapascal No Conversion Required
28 Day Compressive Strength of Concrete: 15 Megapascal --> 15 Megapascal No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Ld = (0.125*fy_steel)/sqrt(f_c) --> (0.125*250)/sqrt(15)

Evaluating ... ...

Ld = 8.06871530459878

STEP 3: Convert Result to Output's Unit

0.00806871530459878 Meter -->8.06871530459878 Millimeter (Check conversion here)

FINAL ANSWER

8.06871530459878 ≈ 8.068715 Millimeter <-- Development Length
