Digital Simulation of Wind Load Effects

The time domain solution of the equations of motion of structures subjected to a stochastic wind field is often obtained by a step-by-step integration approach. The loading is often described by simulated time histories of the aerodynamic force. In this paper different simulation schemes that are based on wave superposition, linear filtering and recursive approaches are discussed, e.g., summation of wave form, state space modelling, auto regressive and moving averages, and the Karhunen Loeve expansion.
