LIMIT STATE DESIGN OF STRUCTURAL PARTS AT AND IN THE GROUND
This paper briefly comments on some shortcomings in the Eurocode 7 standard ULS 1B, which proposes ultimate limit states for designing structural states at and in the ground, and presents several aspects of the German pre-standard DIN V 1054-100 and the German National Application Document (NAD) of April 1996, which attempt to avoid these shortcomings. The ultimate limit states were introduced to reconcile the structural Eurocodes. The resulting compromise has three disadvantages from a geotechnical viewpoint. DIN V 1054-100 is intended to: (1) incorporate established global factors; (2) avoid arbitrary interpretations of the partly vague EC7 text; and (3) avoid over- or under-design in cases of well-established practice. Shallow and spread foundations are treated first. Groups of piles and anchors are treated similarly. The same concept can be used for retaining structures. Uphill and seepage forces can be incorporated by taking effective forces in the soil skeleton and in structural parts of the ground. Possible redistributions of structural forces are discussed briefly. The proposed concept achieves the main objectives of DIN V 1054-100, but is not intended as a final solution. The author suggests that the geotechnical community should defend ground engineering and well-established design methods.
