Eurocode 7 – second generation – spread foundations
Eurocode 7 – second generation – spread foundations
In the new second generation version of Eurocode 7, Part 3 the limit state design for various geotechnical structures is outlined. Spread foundations are covered in Clause 5 of this part where requirements for the verification of ultimate and serviceability limit states are provided. In comparison to the current version of Eurocode 7 the requirements have been improved first by revising the structure of this clause so that it is now unified and consistent with the other clauses in this part and follows the design-path defined in Part 1. In addition, various aspects addressing the limit state design of spread foundations have been complemented or modified such as the inclusion of the well-known Terzaghi-Buisman method for calculating the bearing resistance in the main text, the explicit consideration of rock mass as well as various calculation models provided in Annex B, e.g. models for punching failure and foundation settlement evaluation. The present paper provides an overview of the design of spread foundations according to the new Eurocode 7. A simple design example illustrates the design procedure.
