94 The footbridge “Roerdomp” is located in the protected natural site of Natura 2000, home to the “roerdomp” birds. Spanning the scenic Kalkenvaart near Ghent, the bridge harmoniously blends with its surroundings, showcasing a simple yet elegant design. SCIA Engineer plays a crucial role in verifying the arch’s resistance to global buckling. Through nonlinear analyses and an initial deformation mirroring the first instability mode, the bridge’s stability is confirmed, addressing buckling concerns. Additionally, SCIA Engineer ensures dynamic comfort for pedestrians, assessing the impact of their movement. By defining the structure’s eigenmodes and adhering to SETRA guidelines, dynamic calculations reveal minimal risks of vibrations during pedestrian circulation. Accelerations remain below the 1.0 m/s² threshold, providing a comfortable and secure experience for bridge users as per the SETRA guide.
