Design Aids for RCC Beams and Columns

This is an Android app for Design of Beams and Columns.
This App will be very useful for Design of Rectangular Beams, Rectangular Columns, Circular Columns,

If you click on the link in your Android phone,, it will ask for installation. You can install and then open. You will see 3 buttons in the first screen showing Rectangular Beam, Rectangular Column, Circular Column. If you click on any of the buttons it will take you input screen of Design page. There will be some default values and you just click on Calculate button. You will see the calculations of design procedure below the Calculate button. If you get the results, it means it works fine.
For Design of Beams: 
Click on Rectangular Beam in the first screen. It will take you to the input screen of Design of Rectangular Beam input page. There will be some default values and you just click on Calculate Button. You will see the design calculations and results below the Calculate button. If you get the results, it means it works fine.

Then yoi can change Values of Fck- Concrete Strength values M15 to M60, Fy- Steel Strength Values 250 to 550. Then you can edit breadth, depth, effective cover, Moment values and then click on Calculate button. You will get the results below. If the depth of the beam is not sufficient, you will get notification that the depth of beam is not sufficient. Then you increase the value of depth of beam or change both values of width and depth as per your requirement. Then click on calculate button you will get the results.

For Design of Rectangular Columns:
Click on Rectangular Column in the first screen. It will take you to the input screen of Design of Rectangular Column input page. There will be some default values and you just click on Calculate button. You will see the design calculations up to Area of Steel below the Calculate button. If you see the results, it means it works fine.

Then you change Values of Fck- Concrete Strength values M15 to M60, Fy- Steel Strength Values 250 to 550. Then you edit Width in mm, Depth in mm, Effective Cover in mm, Load in KN, Moment Mx in KNM(Moment along X-direction means along Width dimension of column), Moment-My in KNM(Moment along Y-direction means along Depth dimension of column) and then click on Calculate button. You will get the results below the Calculate button. If the size is not sufficient, you will be prompted with 'sz not enough' notification on right side of Calculate button. If you get sz not enough message, increase the Width / Depth values as per your requirement. Then click on Calculate button you will get the results.

For Circular Columns:
Click on Circular Column in the first screen. It will take you to the input screen of Design of Circular Column input page. There will be some default values and you just click on Calculate button. You will see the design calculations up to Area of Steel below the Calculate button. If you see the results, it means it works fine.

Then you change Values of Fck- Concrete Strength values M15 to M60, Fy- Steel Strength Values 250 to 550. Then you edit Diameter in mm, Effective Cover in mm, Load in KN, Moment Mx in KNM(Moment along X-direction means along Width dimension of column), Moment-My in KNM(Moment along Y-direction means along Depth dimension of column) and then click on Calculate button. You will get the results below the Calculate button. If the size is not sufficient, you will be prompted with 'sz not enough' notification on right side of Calculate button. If you get sz not enough message, increase the Diameter values as per your requirement. Then click on Calculate button you will get the results.

 

General Notes:
Design Aids to IS-456-1978 is published by BIS as special publication SP-16 in 1983.Most of Civil Engineers use the tables and charts in that publication for design of beams and columns. Since it was published in 1983, the limitation of materials concrete is M15 to M25 and Steel Fe250 to Fe500. Now the concrete technology developed a lot and Euro code starts with Concrete M30 to M60 and Steel Fe500 to Fe550. This app includes both Euro standard and Indian standard with Concrete M15 to M60 and Steel Fe250 to Fe550. The usage is very simple just replace the existing values in the app with your real design values and click on Calculate button to get results of your design. If the section is not sufficient you will be prompted that size is not enough.
