...David Perozzi; Alexander M. Puzrin Determining earth pressure-induced moments in the active limit state is critical for the safety assessment of retaining structures. While traditional design methods assume a Coulomb's resultant force acting at one-third of the wall height, the literature suggests...

...Fengwen Lai; Ningning Zhang; Songyu Liu; Dayu Yang Active earth pressure on retaining structures supporting a narrow column of soil cannot be properly analysed using Coulomb's theory. Finite-element limit analysis (FELA) shows that the soil forms multiple failure surfaces if the soil column...

...Chuhan Deng; Stuart K. Haigh A series of centrifuge tests was conducted to explore the deformation mechanisms and earth pressures mobilised in loose and dense sand for a complete set of passive movement modes of a rigid retaining wall: rotation about the top and base and translation. Sand...

In this paper it is shown that accumulated loads acting on a building eventually lead first to a local limit state with failure in the vicinity of the building, followed...

... of an approximately rigid rotation around a point located close to the wall base, it is assumed that active and passive pressures are fully mobilised up to a certain depth from the excavation level. Below this depth, a simplified distribution of earth pressure is considered, with values that are not predetermined...

...B. Friedli; D. Hauswirth; A. M. Puzrin The problem of the limiting landslide pressure on an obstacle was first formulated in 1944 by Robert Haefeli of ETH Zurich, who recognised that the kinematics of the problem does not allow for classical active and passive earth pressure theories to be applied...
