This paper investigates an improved soil-pile foundation-bridge system against earthquake motions and a honeycomb shaped WIB (Wave Impeding Barrier) measure for reduction of traffic-induced vibration. Formulation is conducted in the hybrid method between the finite element for the near field and the boundary element method for the far field. The two-dimensional analysis includes the nonlinear soil and structure behavior for in-plane as well as out-of-plane motions. Focusing on the different types of vibrations of a highway bridge, parameter studies are conducted for the system response in transversal (in-plane) and longitudinal (out-plane) directions. From the results, the advantages of soil improvement are interpreted for the seismic and traffic-induced vibration problems.
