Seismic behaviour of earth retaining structures

Past activity on this topic was related to investigate the behaviour of earth retaining structures, such as retaining walls, that frequently represent key elements of many constructed facilities and their stability is very important, in particular when they are used in seismically active areas. While significant advances have been made in the design of gravity type retaining walls under seismic loadings, little progress has been achieved in the analysis of the seismic response of flexible retaining walls, that is a challenging geotechnical problem, for which the dynamic soil-structure interaction plays a critical role. Simplified pseudo-static approaches are usually adopted in the current practice, but they do not allow a realistic assessment of the performance of these structures in dynamic conditions. A validation of existing pseudo-static approaches, or the introduction of novel simplified methods for design, requires the preliminary investigation of the problem by fully dynamic soil-structure analyses, involving the numerical determination of stress state, bending moments, displacements, and spatial and temporal variability of accelerations.

More recently the fragility curves for rigid earth retaining systems have been investigated on the basis of numerical modeling.
