3. Results and discussion The main results obtained from the finite element analysis carried out in SolidWorks Simulation® (Fig. 7) can be summarized as follows: • The critical regions are located near the supports ( ≤ 200 MPa) and the largest cone diameter ( ≤ 360 MPa) (Fig. 7a); • In general, the maximum principal stresses in the steel structure are less than 170 MPa; • In general, the maximum principal stresses induced in the concrete are greater than -80 MPa and less than 19 MPa; • The maximum vertical displacement was registered near the expansion joints, at the upper connection, with a value of approximately 13 mm (Fig. 7b); the vertical displacement calculated at the bottom expansion joint was about 4 mm. This reveals that the expansion joints installed, with an allowable displacement of 80 mm, are very well dimensioned and do not introduce stresses in the structure.
