I want to analyze a tall building for performance based wind design, How and where can I get the time-history wind load function ?.
The time history function of wind load for non-linear dynamic analysis can be obtained using a combination of measurements and simulations. Here are some general steps to follow:
It is important to note that the specific process for obtaining the time history function of wind load for non-linear dynamic analysis may vary depending on the application and specific requirements.
Mourad el Idrissi Many thanks for your replying, but the frequency domain analysis is invalid in an inelastic system, so I need to generate time history wind load from a PSD function.

How can I get the time history function of wind load for non linear dynamic analysis ?
The time history function of wind load for nonlinear dynamic analysis can be obtained using a combination of experimental and analytical methods.
Experimental methods involve measuring wind loads on structures using wind tunnels or full-scale testing. These methods can provide a reliable time history of wind loads, but they can be expensive and time-consuming.
Analytical methods involve using computational fluid dynamics (CFD) to simulate the wind loads on the structure. This can be done using specialized software that can model the wind flow around the structure and calculate the resulting loads. However, these simulations can be computationally expensive and may require significant expertise to set up and interpret.
Once the time history of wind loads has been obtained, it can be used as input for nonlinear dynamic analysis. This type of analysis involves modeling the behavior of the structure under the time-varying wind loads, taking into account the nonlinear behavior of the materials and the dynamics of the structure.
It is important to note that the accuracy of the time history function of wind load will depend on the quality of the measurements or simulations used to obtain it, as well as the assumptions and simplifications made in the nonlinear dynamic analysis. Therefore, it is essential to carefully validate the inputs and assumptions used in the analysis to ensure the reliability of the results.
