Článek popisuje některé vlastnosti nově implementovaných modulů ve verzi 3.30 programového systému NEXIS. Jsou nastíněny koncepce a směry dalšího vývoje software v oblasti návrhu a posuzování betonových konstrukcí, které by měly být předmětem širší odborné diskuse.

Modern civil engineering structures can achieve considerable economy in construction by combining hybrid systems of steel and concrete or precast and cast-in-place concrete. The design of the structures combines both precast and cast-in-place techniques to obtain economy in construction, and maintains a high standard of quality while reducing the time needed to complete construction. „CONSTRUCTION STAGES“, „PRESTRESSING“, and „TDA“ (Time Dependent Analysis) are modules of ESA PRIMA WIN program system designated for the analysis of prestressed concrete and composite structures with respect to step-by-step construction, change of boundary conditions, and rheological effects of concrete. The modules make possible the structural analysis of both prestressed concrete and composite structures, successive assembling or casting of structural elements, progressive construction of cross-sections, gradual application of loads and prestressing, and removal of temporary structural elements. Special construction technologies can be modelled, such as cantilever segmental construction with both precast and cast-in-place segments, launching, cable stayed structures, making simple beams continues including successive casting of composite slab, or gradual construction of multi-storey buildings.
