EN 1992 Verification # 1

reinforced concrete design

Information presented on this page is intended to demonstrate the section design convergence of EN 1992-1-1: 2004 provisions for isolated foundations that can be achieved with SkyCiv. All examples are referenced from the following books:

Book 1: Bill Mosley, John Bungey, and Ray Hulse. Reinforced Concrete Design to Eurocode 2 (Seventh Edition), 2012.

Example # 1 Design of Axially Loaded Isolated Footing

reference: Book 1, p.300.

A pad footing is required to resist characteristic axial loads of 1000 kN permanent and 350 kN variable from a 400 mm square column. The resulting shear, moment, load transfer, and development length are compared with manual calculations. The foundation model lies in the X-Z plane.

GEOMETRY AND MATERIAL PROPERTIESAxially Loaded Isolated Footing Design, EN 1992

Figure 2: Footing model and material properties of example #1

Two characteristic loads are considered:

\(  \text{G} = 1000.00 \text{ kN} \)
\(  \text{Q} = 350.00 \text{ kN} \)

The results of service and factor load combination are computed in reference to EN 1990.


The analysis is done using the rigid conventional method. See the Isolated Footing User Manual for more explanation on using SkyCiv Foundation.


The most significant results are compared in the table below:

Notes: Discrepancies on some values are due to the following:

*Actual self weight of column and footing are considered in SkyCiv. In addition, SkyCiv requires a column height greater than zero.

*SkyCiv calculates actual measurement of the effective depth for both directions.



SkyCiv Foundation module offers an innovative and user-friendly interface for the design and analysis of an isolated footing in accordance with EN 1992-1-1: 2004 .
