Improving sustainability and safety of the built environment is a major challenge of current European policies. In this regard, topology optimization may represent a powerful design tool for the selection of more suitable structural systems, by maximizing the performance efficiency while minimizing the overall material consumption. The accurate prediction of stochastic responses of structures induced by natural hazards is crucial to achieve reliable and effective designs. Therefore, it is of great significance to incorporate the impact of uncertainties into topology optimization of buildings, especially in the case of large structures. Despite recent technological advances, existing theoretical frameworks for the identification of optimal lateral bracing systems for tall buildings remain inadequate to overcome computational challenges of incorporating stochastic responses to optimization procedures. Thus, this project aims at contributing to the development of theoretical frameworks that integrate the random vibration theory with topology optimization using both fully non-stationary models and single pulse-like near fault records. Furthermore, the project is committed to producing positive socio-economic impacts in the medium- and long-term through the conversion of scientific and technical results into real-world applications, and it is intended to disseminate the benefits of automated techniques in the definition of advanced designs.
