Typically, an essentially low number of standard structural elements used in an engineering practice in general and in civil constructions in particular. As such, examples c an be given: beam, plate, shell and their reinforced analogues. Nevertheless, there are approaches that are able to offer the more complex systems of structural elements. For example, using topology optimization methods, it is possible to obtain rather com plex variants of structures that are quite unique and are implied in execution only with the support of additive manufacturing technologies. Modern specialists miss opportunities based on such approaches to obtain a system of new and more effective for ind ustry structural elements. Such elements can be standardized, their cost can be reduced, and used in everyday design practice. This research shows examples of the use of new structural elements in application to horizontal slab for construction engineering and plates in general. Their effectiveness of proposed solutions are shown and analyzed. This work was supported by the Russian Science Foundation under Grant No. 20 11 20230. SPECIAL
