Abstract
Objective: This study presents a comparative analysis between conventional monolithic construction and the CUBIAX system in commercial buildings. The paper examines traditional monolithic construction alongside contemporary construction techniques that incorporate prefabricated void-forming elements made of plastic and rubber within reinforced concrete slabs and foundations. The innovative CUBIAX system enables faster and more rational construction by reducing concrete consumption, thereby decreasing the self-weight of the structure. Reduction of dead load is a fundamental objective in structural engineering; achieving this enhances the ductile behavior of structures under dynamic and seismic loading. Consequently, the application of the CUBIAX system represents a highly effective solution, particularly for structures located in seismically active regions. Methodology: The study involves structural analysis of systems designed using the conventional monolithic method, employing established reinforced concrete design procedures in accordance with national regulations and European standards, specifically Eurocode 2 (EC2) and Eurocode 8 (EC8). Similarly, the analysis of structures utilizing the CUBIAX system is conducted using verified design approaches based on Eurocodes and widely adopted European engineering practices. Results: In direct comparison with conventional reinforced concrete slabs, CUBIAX voided flat slabs demonstrate superior technical performance and are generally more cost-effective due to reduced material consumption. Furthermore, the overall costs of the supporting structural system and foundations can be significantly reduced as a result of the decreased dead load of the optimized slab system. The degree of optimization varies depending on project-specific conditions. The increased span capacity and optimized cross-sections of load-bearing elements contribute to enhanced flexibility in load distribution and allow for larger usable floor areas. Due to the reduced permanent load, CUBIAX slabs can be designed to be approximately 5–10% thinner than conventional reinforced concrete slabs while maintaining equivalent service loads and deformation limits. Additionally, construction execution is faster, resulting in time savings without compromising structural safety, stability, or ductility as prescribed by relevant standards. Conclusion: Based on the conducted analyses, the CUBIAX system proves to be a more suitable and efficient solution within the fields of structural engineering and architecture. Comparative evaluation with conventional monolithic construction indicates that the CUBIAX system offers advantages across multiple aspects of design and construction, including structural performance and efficiency. It effectively reduces: ● Structural self-weight ● Construction time ● Project costs ● Labor requirements ● Complexity of installation while improving seismic performance and overall structural behavior. The findings demonstrate that the CUBIAX system addresses many of the limitations associated with traditional reinforced concrete construction methods.
