Before we delve into the calculations, let's set the foundation. In this four-legged stirrup arrangement, the cutting length for stirrup-1 and stirrup-2 is identical, simplifying our approach. The crucial formula for calculating the cutting length "L" is: L = [(2 × (a + b)) + hook length) − (90° bend + 135° bend)] First, we establish "a" by finding the value of "X," which represents the center-to-center spacing between the longitudinal bars horizontally. Using the formula: X = (Width of column − (2 × Clear cover + 2 × Diameter of stirrup + 2 × Diameter of main bar / 2)) / 3 We find X = 111.33mm. With "X" in hand, we determine "a": a = (2 × X) + (2 × ½ × Diameter of main bars) + (2 × ½ × Diameter of stirrup) a = 250.66mm. Next, we calculate "b": b = Column depth - (2 × Clear cover + 2 × ½ × Diameter of stirrup) b = 512mm. Now, onto the grand finale! The cutting length "L" for stirrup-2 takes shape: L = [(2 × (a + b)) + hook length) − (90° bend + 135° bend)] Substituting values: L = [(2 × (250.66mm + 512mm)) + (10 × Diameter of rebar) − (3 × 2 × Diameter of rebar + 2 × 3 × Diameter of rebar)] The result: L = 1589.32mm. And there you have it! 🎉 The cutting length for both stirrup-1 and stirrup-2 in this four-legged stirrup arrangement is 1589.32mm.
