PROCEDURE

Configuration

• Select the width of supports w1 and w2 within the range of 0.23 m to 2 m.
• Select the nominal cover in the range of 20 mm to 70 mm.
• After setting the parameters, click on the “Configure” button.
• Proceed to the next step by clicking the “Next” button.

Calculations

• Calculate effective cover and submit your answer. After three incorrect attempts, the formula and correct answer will be displayed.
• Similarly, calculate:
• Effective cover
• Factored load
• Effective span
• Shear force
• Bending moment
• Click on Next Arrow for the next level after calculation.

Overall Depth v/s Ast Graph with Calculations

• Calculate the effective depth required for a balanced section.
• Determine the corresponding overall depth (D).
• Compute the area of steel (Ast) for the balanced section.
• Select different values of total depth (D) in mm.
• Submit the values and click on the “Plot Graph” button to observe the D v/s Ast graph.
• Repeat this for a minimum of 4 readings.
• Click the “Next” arrow to continue.

Calculation of Reinforcement Bars

• Select the provided total depth value (D); the effective depth and Ast will be calculated.
• Select bar diameter and calculate the number of bars required.
• Trials can be taken by changing the bar diameter and observing the changes.
• After the trials, click on the "Next" arrow for the next level.

Calculation for Shear Force at Critical Section

• Calculate shear force at the critical section.
• Calculate shear stress at the critical section.
• Compute design shear strength of concrete.
• Calculate maximum shear strength.
• Provide 2-legged stirrups and select the grade of steel for stirrups. Spacing will be obtained.

Economical

• Select the grade of steel for longitudinal reinforcement, enter its cost per kg, and then click on "Submit".
• Select the grade of steel for stirrups, enter its cost per kg, and click on "Submit".
• Select the grade of concrete, enter its cost per kg, and click on "Submit".
• Observe the cost for different values of D.
