Towards preparation of national annex to Eurocode 7: From aspect of retaining walls

Unlike the other eurocodes where structure designing is fairly clear, there are three design approaches offered in Eurocode 7 and sets of applied partial factors. After accepting Eurocode 7, each country has to decide on two very important decisions related to the selection of appropriate design approach according to which designing of geotechnical structures is going to be performed and define adequate partial factors. Selection of appropriate design approach is based on analyses of certain geotechnical problem both with actual and proposed methods. Therefore, it should be find out which approach is the closest to hitherto calculation 'style', which compatibility of 'old' and new method will serve as a base for selecting appropriate design approach. Moreover, it will be tested with different partial factors in order to obtain approximately the same size of structural elements or construction, which similarity will suggest the value of partial factors. Analyses and verifications are performed for such purposes for retaining walls, which conclusions, presented below, lead to solution that can be used in the region.
