This study presents an analysis of dry masonry retaining structures based on yield design theory : the structure stability is assessed using rigid block and shear failure mechanisms in the wall and its backfill. An application of this simulation on 2D scale-down brick and wood models is then addressed, showing close agreement between theoretical predictions and experimental results. Finally, the possibility of widespreading the study to periodic dry joint and dry-stone retaining structures is discussed.

“…This study has been completed by full-scale field experiments on 2 . 5 m high drystone walls backfilled until failure with a cohesionless soil; the experimental protocol can be found in Colas et al (2010b). The present paper presents an innovative analysis of drystone retaining walls based on these theoretical and experimental data.…”

International audienceDrystone walling is a widespread form of construction that utilises local materials. It has received growing interest over the past few years, owing to the recognition of its rich heritage in the framework of sustainable development. However, the growth of dry masonry has been slowed by the lack of scientific evidence proving its reliability. The authors have previously established a model based on yield design to assess drystone wall stability. This theoretical approach has been supplemented by field experiments on full-scale drystone retaining walls that were backfilled until failure with a cohesionless soil. These field experiments followed a first set of experiments in 2002-2003 in which the walls were loaded using hydrostatic pressure. The aim of these experimental programmes was to achieve better understanding of drystone masonry behaviour under loading, and of its failure mode. The present paper consists of a comparative analysis of these theoretical and experimental results, and provides a richer understanding of drystone retaining wall phenomenology. Further perspectives on this work are presented in the conclusion

“…There is now a renewed interest in dry stone masonry. As many walls build in the 19th and at the beginning of the 20th century are aging, modern engineering tools are needed to assess their mechanical performances [91,92]. The environmental impact of natural stones and aggregates is extensively discussed by Calkins [84].…”

Sustainable Buildings: An Ever Evolving Target

Environmental considerations have called for new developments in building technologies to bridge the gap between this need for lower impacts on the environment and ever increasing comfort. These developments were generally directed at the reduction of the energy consumption during operations. While this was indeed a mandatory first step, complete environmental life cycle analysis raises new questions. For instance, for a typical low thermal energy consumption building, the embodied energy of construction materials now becomes an important component of the environmental footprint. In addition, the usual practice in life cycle analysis now appears to call for some adaptation-due to variable parameters in time-to be implemented successfully in building analysis. These issues bring new challenges to reach the goal of integrated design, construction, commissioning, operation, maintenance, and decommissioning of sustainable buildings.
