Logo of Eurocode 7. In the Eurocode series of European standards (EN) related to construction, Eurocode 7: Geotechnical design (abbreviated EN 1997 or, informally, EC 7) describes how to design geotechnical structures, using the limit state design philosophy. It is published in two parts; "General rules" and "Ground investigation and testing".
Section 7: Specific rules for composite steel-concrete buildings; Section 8: Specific rules for timber buildings; Section 9: Specific rules for masonry buildings. Section 10 contains the fundamental requirements and other relevant aspects of design and safety related to base isolation of structures and specifically to base isolation of buildings.
The standard also encompasses the structural design of bridge foundations [4] as well as the design and requirements of bridge bearings for both ordinary and moving bridges. [6] [7] In 2010, BS 5400 was superseded by the Structural Eurocodes for the design of new bridges. However, BS 5400 still serves as the foundation for assessment standards ...
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
All of the EN Eurocodes relating to materials have a Part 1-1 which covers the design of buildings and other civil engineering structures and a Part 1-2 for fire design. The codes for concrete, steel, composite steel and concrete, and timber structures and earthquake resistance have a Part 2 covering design of bridges.

A general bearing failure occurs when the load on the footing causes large movement of the soil on a shear failure surface which extends away from the footing and up to the soil surface. Calculation of the capacity of the footing in general bearing is based on the size of the footing and the soil properties.
Eurocode 4 is divided in two parts EN 1994-1 and EN 1994-2. Eurocode 4 is intended to be used in conjunction with: EN 1990: Eurocode - Basis of structural design; EN 1991: Eurocode 1 - Actions on structures; ENs, hENs, ETAGs and ETAs for construction products relevant for composite structures;
