Optimizing Finite Element Meshes for Structural Analysis: The Role of GiD Pre-Processing in Multi-Story Building Models

This study explores the integration of GiD pre-processing software with ETABS to enhance the finite element modeling of large, complex, multi-story buildings under diverse loading conditions. The research highlights the benefits of using GiD for customized meshing of slab systems, which allows for precise control over mesh density and element quality. Through a case study of an eight-story reinforced concrete structure, the study demonstrates how GiD improves analysis accuracy and computational efficiency by reducing process time and minimizing mesh-related errors. The results indicate that GiD’s refined meshing capabilities enhances the structural model’s accuracy, improving load distribution, straining actions calculations, deflection accuracy, and load transfer representation under gravity loads. In addition, GiD’s approach leads to more reliable predictions of natural periods, lateral displacements, and story drifts under seismic conditions. This integration offers valuable insights for engineers seeking to optimize FEA workflows for complex structures.
