Two tragic tsunamis that devastated the west coast of Sumatra Island, Indonesia in 2004 and North East Japan in 2011 had
damaged bridges to various extents. Due to the increasing popularity of cable stayed bridges, it is vital that more attention
be paid to the effects of tsunamis on this type of bridges. The objectives of this research are to identify mechanism of wave
propagation around cable stayed bridge, to evaluate the physical phenomena of tsunami force on cable and deck of cable stayed
bridge, to determine the distribution of hydrodynamic, impulsive, buoyant and uplift forces on cable stayed bridge due to tsunami
by simulating using numerical and computational analysis. In order to understand the tsunami force on cable stayed bridges,
tests were carried out to study the characteristics of hydrodynamic force at different wave heights. The fluid structure interaction
between the cable stayed bridge and tsunami for numerical model based on finite element analysis by LS-DYNA was conducted.
Numerical models of tsunami impact on the bridge superstructures were developed.
