Abstract: Performance-based design was widely used to realize structural multi-level performance objectives under all possible external loadings during life cycle. Based on performance-based earthquake engineering approach being pursued by Pacific Earthquake Engineering Research (PEER) Center, the probabilistic assessment framework of performance-based wind engineering was developed. According to the close-form expression of mean annual frequency of exceeding limit state for seismic design, the close-form expression of mean annual frequency of exceeding structural wind-resistant demand was derived under some simplified assumptions, with the consideration of random features of wind velocity at specific site. A typical high-rise building was adopted as an example to present the probabilistic assessment of performance-based wind engineering, in which the peak acceleration and displacement at key joints were acted as the evaluation criteria of the wind-resistant performance levels.
