In the literature [6,8,28]. 5.4. Effects of the Barrier Height and Airflow Speed on the Aerodynamic Coefficients of the BridgeThe responses of the bridge with five different barrier heights (i.e., 0, 8, 10, 12 and 13.5 cm) to different airflow speeds (5, 10, 15 and 20 m/s) are presented in Figure 9a,b for the overturning-moment coefficient (CBM) and the side-force coefficient (CBY). As shown in Figure 9a, CBM was only 0.02 for the bridge without a barrier for all applied airflow speeds, while it increased sharply to more than 0.15 when a barrier was used with a height of 8 cm. This meant the barriers introduced an adverse mechanical effect to the bridge in terms of the overturning moment. According to Figure 9a, when the barriers were used, CBM presented a non-linear relation relative to the barrier height, as its value reduced from 0.169 to 0.144 when the barrier height increased from 8 cm to 10 cm, which was then maintained within a range of 0.162 to 0.165 for the barrier height from 12 to 13.5 cm for all the applied airflow speeds. As shown in Figure 9b, for the airflow speeds from 10 to 20 m/s, the side-force coefficient (CBY) clearly increased with the barrier height. For example, when an 8 cm barrier was used, the average CBY increased from 0.72 (no wind barrier) to 0.91, and when the barrier height increased from 12 cm to 13.5 cm, CBY increased sharply from 1.07 to 1.22. Therefore, a barrier with a smaller height introduced a smaller side force on the bridge. In comparison to the barrier heights, the airflow speeds presented less of an effect on CBY, as the variation in CBY was within 0.1 when different airflow speeds (10, 15 or 20 m/s) were applied.The changes in CBM with the airflow speeds are presented in Figure 10. It can be seen that, in general, CBM decreased with the increase of airflow speed above 10 m/s for all the tested barriers and such decreases in CBM with the airflow speed were more significant for taller barriers. For example, when the. Airflow: Basic understanding of Architecture of Airflow and familiar with the following terminology of the DAG’s, Airflow config, Airflow scheduler, Airflow web-server.
