Computer Simulation of Stochastic Wind Velocity Fields for Structural Response Analysis: Comparisons and Applications

Table 3

Computational efforts required by the three different methods for digital wind simulation (T₀ and 𝑇_𝑠𝑖𝑚 denote the computer times necessary for performing the “phase 0” and one single simulation in the “phase 1”, resp.).
