T Shaped RCC Beam Design Excel Sheet

T Shaped RCC Beam Design

Concrete beams are very commonly used for all types of buildings and structures. This is because concrete beams are versatile and cost effective. The composite nature of reinforced concrete means that the expensive steel can be placed exactly where it is needed while the concrete provides fire and durability protection as well as providing depth and compressive strength.

T shaped beams can be cost effective as an alternative to traditional beam and slab construction in some conditions and can be very strong. This is because when the beam is subjected to sagging bending moments the concrete at the bottom of the beam is neglected in the design. This means that the concrete in the bottom of the section can be omitted entirely, except for the width required to hold the reinforcing steel in place.

In this way T shaped beams are cost effective by removing a lot of unnecessary concrete from large beams. The T shaped beam can be designed as a large, wide rectangular beam so long as the neutral axis is within the flange of the beam. This ensures that there is none of the omitted concrete in the bottom of the beam is being subjected to compressive forces. The only parts of the beam which are omitted are in the tensile zone.

T Shaped Beam Design - Inputs

The design of T shaped beams can be completed similarly to rectangular beams so long as the neutral axis is in the flange at the top of the beam. If this is the case the beam will act exactly like a rectangular beam. If the neutral axis is below the flange the beam must be designed as a T beam which is more complex.

First the designer must input the geometry of the proposed T shaped beam and the loading conditions. The loading conditions can be determined from a beam analysis spreadsheet such as the Beam Analysis Spreadsheet. The Beam Analysis Spreadsheet is included in the CivilWeb Reinforced Concrete Beam Design Excel Bundle available at the bottom of this page for only £30.

Now the CivilWeb T Shaped RCC Beam Design Excel Sheet calculates the position of the neutral axis. This determines the method used for the detailed design of the beam. The spreadsheet checks the proposed beam dimensions for suitability. The designer can adjust the dimensions in order to suit the loading conditions, for example deepening the flange in order to ensure the neutral axis is within the flange. The spreadsheet includes unique design and analysis tools which show the designer the optimum beam dimensions, eliminating the need for iterative calculations.

The spreadsheet then calculates the reinforcement required in the top of the flange and in the bottom of the web of the beam in order to resist the bending moments and shear forces acting on the beam. These calculations are completed in accordance with either BS EN 1992 or BS 8110. The spreadsheet includes our unique reinforcement design tool which shows the designer at a glance the optimum bar size and number.
