Reinforced Concrete Column Design Spreadsheet

The CivilWeb Reinforced Concrete Column Design Spreadsheet Suite is a collection of concrete column design spreadsheets. This suite provides all the tools the designer needs to design reinforced concrete columns in accordance with BS EN 1992. The suite includes spreadsheets for the design of uniaxial, biaxial rectangular columns and circular columns. The spreadsheets include unique interaction diagrams which show the designer at a glance exactly what reinforcement is required allowing an optimised design to be completed in minutes.

The CivilWeb Reinforced Concrete Column Design Spreadsheet Suite can be purchased at the bottom of this page for only £30. Alternatively the Reinforced Concrete Column Design Spreadsheet Suite is included in the full Concrete Design Suite which includes all of our reinforced concrete design spreadsheets. This is our best value design bundle and can be purchased at the bottom of this page for only £50.

Circular Column Interaction Diagram Spreadsheet

Concrete Columns

Reinforced concrete columns are very common in all types of concrete and steel framed structures. Reinforced concrete is economical, durable and fire resistant. It can also be easily moulded to any required shape or size.

Concrete is very strong in compression making it well suited to columns supporting a purely axial load. Where bending moments are included or the slenderness of the columns introduce a risk of buckling, structural steel reinforcement is required to resist any tensile forces produced in the column.

Concrete Column Design - Inputs

Firstly the designer must input the forces which the column is being designed to resist. The spreadsheets do not complete this analysis, they allow the designer to enter any value of bending moments and shear forces from a separate frame analysis.

Each spreadsheet allows the designer to select up to 6 different load cases for analysis. The spreadsheet analyses these load cases and determines which load case is critical for the design of this particular column. This is very useful as the interaction between axial force and bending moment makes determining the critical load case is impossible without detailed analysis. These spreadsheets remove the need for the designer to iteratively test several different load cases on each design saving precious time for the designer.

After the designer has input the loadings they must now enter a trial size for the proposed column. The CivilWeb Reinforced Concrete Column Design Spreadsheet Suite will then analyse this proposed column size and check its validity in accordance with BS EN 1992. If the column size is not valid the designer will be asked to alter the dimensions of the column.

When a valid column size has been determined, next the spreadsheet designs the required reinforcement. The spreadsheet does this by creating a column reinforcement interaction chart which shows the designer exactly how much reinforcement is required to resist any combination of axial and bending loads.

CivilWeb Reinforced Concrete Column Design Spreadsheet Suite

The CivilWeb Reinforced Concrete Column Design Excel Sheet Suite includes the following spreadsheets;

RCC Column Design Excel Sheet

This easy to use design spreadsheet can be used complete the design of simple uniaxially loaded rectangular concrete columns. Columns loaded with axial loads and moments in only one direction are very common so this spreadsheet is designed to be as simple and quick to use as possible. Using this spreadsheet a column design in accordance with BS EN 1992 can be completed in minutes. The spreadsheet allows the designer to input up to 6 load cases which are then analysed to determine the critical case. This is then used to design the reinforcement required. The designer is also presented with a reinforcement interaction chart which shows exactly where the column can be optimised to suit the loads and a desired bar size and spacing.

Biaxial Column Design Spreadsheet

This spreadsheet is more powerful and can be used to design biaxially loaded columns. Columns which can be subjected to moments in either or both directions are less common but can still occur. This spreadsheet can be used to design concrete columns with structural reinforcement designed to resist moments in either direction along with axial loads. The spreadsheet includes more load inputs including bottom and top moments. The spreadsheet also allows the designer to input the details of the connecting beams which are used in the analysis of the load cases. The spreadsheet analyses these load cases and then determines the reinforcement required. The spreadsheet also produces two reinforcement interaction diagrams, one for each plane of bending moments.

Circular Column Design Spreadsheet

This spreadsheet can be used to design circular concrete columns which can be loaded with axial forces and bending moments acting in any direction. The spreadsheet allows the designer to input up to 6 different load cases which the spreadsheet analyses for the most critical case. The spreadsheet calculates the reinforcement required to accommodate the critical load case. This spreadsheet also includes a reinforcement interaction chart which makes improving the column design simple.

CivilWeb Reinforced Concrete Column Design Spreadsheet Suite

The CivilWeb Reinforced Concrete Column Design Excel Sheet Suite includes all the tools required for the design of any reinforced concrete column. The suite includes three spreadsheets covering uniaxial loads, biaxial loads and circular columns. The spreadsheet completes all the calculations in accordance with BS EN 1992. The spreadsheets inbuilt column interaction charts speed up the design process, allowing a fully optimised design to be completed in minutes.
