The thickness of each element has been defined in the Property Section Manager module. Table 4 Geometric properties of structural elements in the model DECK CEN.

Figure 11 Deck plan showing the layout of longitudinal and transverse reinforcements and columns in Abaqus 2.7 Geometric Properties of the Model The finite element mesh was generated using free meshing with the medial axis algorithm. The mesh consists of both quadrilateral and triangular shell elements, with a global element size of 40 mm. The final model contains 71 996 nodes and 72 259 elements, including 71 822 quadrilateral elements of type S4R and 437 triangular elements of type S3 (Table 5).
