SITE AMPLIFICATION EFFECT ON RESPONSE OF BRIDGE STRUCTURES
This paper focuses on the relative response between two adjacent bridge structures under earthquake loading. The interrelation between non-uniform ground condition, unequal slenderness and dynamic properties of the adjacent bridge structures, non-uniform site amplification of ground motions and unequal soil-structure interaction are considered simultaneously. The applied spatially varying ground motions are simulated stochastically based on the new Australian design spectrum.The numerical analysis of the minimum total gap, that a modular expansion joint must have, is performed using a combined finite and boundary element method. The results clearly reveal the significance of the simultaneous influence of structural, soil and seismic wave properties in proper design of expansion joints.
