The existence of periodic solution and a certain decay property for the nonlinear dissipative wave equation utt - Δu + σ(ut) = f in R × Ω (or R+ × Ω) with the boundary condition u|∂Ω = 0 are proved, where Ω is a bounded domain in Rn and σ(v) is a sublinear function, say, σ(v) = k0|v|-rv, k0 >0, 0<r<1.
