Abstract
In order to evaluate the wind load effect considering the wind speed directionality, the wind speed probability and the directional wind speed-load effect relationship should be known. This paper proposes improved typhoon simulation, the so-called POD-based pressure model and hybrid use of observed records and calculated values. Directional wind speed probabilities are evaluated using an improved method for typhoon winds and a statistical method for non-typhoon winds. Directional wind speeds are evaluated considering the wind load effects of tall buildings.
