The paper explores the possibilities of defining geometry and its behaviors with using ESO digital tools in an integrated structural and architectural design. It is an response to the current needs geared towards sustainability, combining ecological and economic efficiency. The first part of the paper defines the Evolutionary Structural Optimization tools, which were developed specifically for engineering purposes using finite element analysis as a framework. The development of ESO has led to several variations wh...

The objective of the paper was to emphasize the influence of the biological activity on the structural improvement of the compacted clayey pedogenetic horizons of two Chromic Luvisols, by the organic matter bioturbation. The researches were performed on two Chromic Luvisols from Romanian Plain, where the mean annual temperature is 10.5oC and the mean annual precipitation is 548 mm. The analytical data showed that clay content increased from the top layer of both soil profiles (28.9% in P1, and 29.8% in P2), to Bt ...
