Calculate Development Length





Formula

The formula to calculate the Development Length (DL) is:

\[ DL = \frac{D \times S}{4 \times BS} \]

Where:

Definitions

Example

Let's say the nominal diameter of the rebar is 20 units, the stress in the bar at design load is 400 units, and the design bond stress is 100 units. Using the formula:

\[ DL = \frac{20 \times 400}{4 \times 100} \]

We get:

\[ DL = 20 \]

So, the Development Length (\( DL \)) is 20 units.

Development Length Calculation Example

Formula: \( L_d = \frac{\text{f_y} \times \text{d_b}}{4 \times \text{t}_b} \)

Example: \( L_d = \frac{400 \times 20}{4 \times 1.5} \)

How to Compute Development Length

Formula: \( L_d = \frac{\text{f_y} \times \text{d_b}}{4 \times \text{t}_b} \)

Example: \( L_d = \frac{500 \times 25}{4 \times 2} \)

How to Calculate Developed Length

Formula: \( L_d = \frac{\text{f_y} \times \text{d_b}}{4 \times \text{t}_b} \)

Example: \( L_d = \frac{600 \times 30}{4 \times 2.5} \)
