  1. 6. Buckling of End-Bearing Retaining Walls in Clay

    University essay from KTH/Jord- och bergmekanik

    Author : Fredrik Jansson; Nils Nilsson; [2018]
    Keywords : Berliner walls; Critical loads; buckling; finite element model; Eurocode 3; Berlinerspont; Rörspont; kritisk knäckningslast; knäckning; finit element modell; Eurocode 3;

    Abstract : The design of back-anchored retaining walls in Sweden has traditionally not included global elastic instability of the retaining wall as a possible failure mode. Eurocode 3 part 5 (SS-EN 1993-5) requires design of steel structural members for retaining walls to assess the risk of buckling if the normal force exceeds 4 % of the critical buckling load of the retaining wall.
