Abstract:
Many cities have developed with
the rapid growth of the population. Due to the
shortage of land, tall buildings have to be
implicit closeness. In the recent past due to
various advantages, skybridges are adopted
widely to connect adjacent buildings in the case
of wind-induced motion, the vortex shedding
causes a periodic driving force across the
skybridge structure. Flutter and buffeting are
the main aerodynamic instabilities in flexible
bridges. In this research, a numerical
simulation based on CFD was used to
investigate the aerodynamic performance of
skybridges. The numerical simulation was
adopted using ANSYS/Fluent software to
analyze four different skybridge configurations
subjected to various wind forces. Throughout
the simulation process that was carried out, the
interaction of wind speed and cross-section of
the skybridge deck was examined. All three
aerodynamic forces showed an increment when
the velocity increases. Results revealed that
when the edges of the deck cross-section get
smoother, aerodynamic forces acting on the
skybridge get smaller. Hence, the model with
curved edges gives the optimum cross-section
for the construction of a skybridge.
