Jacques Dixmier, AuteurEurocode 4 is the European design code for composite construction; in its so-called ENV version, the scope is limited to "nonsway building" with efficient bracing systems. Therefore, is gives mainly rules to analyze and to check structural eleme[...]

Discrete element methods (DEMs) provide new numerical means to study the behavior of soil-inclusion systems.In some cases, however, the classic DEM fails to model specific aspects of the inclusions. That is why a model based on spar elements is [...]
