Study of Bridge Parameters on Aerodynamic Performance of Steel Arch Bridge

Aerodynamic stability is a condition required in the planning of long span bridges. Not all countries have detailed planning rules for aerodynamic stability. One of the rules that is often referred to for long span bridge planning is the Design Rules for Aerodynamic Effects on Bridges BD 49/01. This paper will discuss the effect of the value of the average wind speed per hour (V_r), mass per unit length (m) and frequency (f) on The Aerodynamic Susceptibility Parameter (P_b), critical velocity of vortex excitation (V_cr), vibration amplitude for vortex excitation (y_max), critical speed for galloping and stall flutter (V_g), and critical speed for classical flutter (V_f) refer to Design Rules for Aerodynamic Effects on Bridges BD 49/01. The value of the average wind speed per hour (V_r), mass per unit length (m) and frequency (f) will be varied for case study of Teluk Mesjid Bridge a steel arch bridgelocated in Riau Province, Sumatra Island of Indonesia.
