САЖЕТАК / ABSTRACT:
The accuracy of finite element analysis (FEM) strongly depends on mesh density, particularly in reinforced concrete (RC) structures where local stress gradients and seismic effects are critical. This study investigates the influence of finite element mesh density on the global and local response of a five-story RC building, with special focus on slab behaviour. Numerical models were devoleped and analyzed in Tower 7, with design and verification performed in accordance with Eurocode 2 (EN 1992-1-1) and Eurcode 8 (EN 1998-1). Two slab mesh configurations were compared to evaluate displacement and moment distributions, required reinforcement, convergence behaviour, numerical stability and computational effort. The obtained results showed that the mesh density has varying levels of influence depending on the type of structural response being analyzed. The findings provide practical guidance for selecting slab mesh density in Tower 7 FEM workflows complaint with Eurocode requirements, balancing accuracu and computational efficiency in seismic-aware RC design.
