A study on comparisons of design wind loads and responses for tall buildings with actual wind load distributions and responses

Generally design wind load and responses are evaluated with the force balance test. Several limitations, however, are included into the force balance test method. Profiles of mean and background wind loads are assumed, and only peak values of wind loads and responses are evaluated by the force balance test. Therefore, shapes of total wind loads and acceleration responses might be improperly evaluated for peculiar types of buildings. In this study, expected problems in evaluating design wind loads and responses due to such limitations in the force balance test method were investigated by comparing evaluation results of the force balance test with actual wind loads and responses derived by advanced conditional sampling (ACS) method for a slender structure and a shear wall type tall building.
