摘要：

The time-history of wind velocity was simulated by using the harmonic superposition method, which was then turned into pressure time-history of wind. By using the ANSYS software, the FEM model for the structural system was constructed, and the structural wind-induced vibration responses under different incoming winds were calculated by using the simulated wind pressure time-history. Moreover, a novel equivalent static wind load was established, where the wind-induced dynamic amplification factor was combined with the instantaneous wind pressure distribution at a specific time. Finally, from numerical examples, the equivalent static wind load distribution based on the minimum vertical reaction forces and the maximum nodal displacement of the truss were obtained. © 2016, Editorial Board of Journal of Shanghai Jiao Tong University.
