Abstract: By using operator decomposition technique and priori estimation of the solution of the equation, we gave the uniform asymptotic compactness of the random dynamical system, and proved the existence of the random attractor for the stochastic suspension bridge equation with additive noise.

Key words: suspension bridge equation, random attractor, additive noise, uniform asymptotic compactness
