LimitState:GEO featured in 'Soil Dynamics and Earthquake Engineering'
LimitState:GEO was used extensively in a recent paper in the international journal, Soil Dynamics and Earthquake Engineering.
Entitled "Pseudo-static limit analysis by discontinuity layout optimization: Application to seismic analysis of retaining walls", the article describes how discontinuity layout optimization (DLO), the powerful analysis technique used in LimitState:GEO, can handle pseudo-static seismic analysis problems.
The paper then goes on to verify the DLO analysis against the work of Mononobe-Okabe and Richard and Elms, examining the effects of wall inertia and combined retaining wall failure modes.
A framework for modelling water pressures during seismic loading within a computational limit analysis framework is then proposed, and discussed in the context of two quay wall failures from the Kobe earthquake.
