Equivalent Static Wind Loading on Buildings: A New Perspective

摘要

A framework for evaluating the equivalent static wind load (ESWL) for any given peak response of buildings characterized by uncoupled motions in the three primary directions is presented. This includes a new description of the background loading based on the gust loading envelope, whereas the resonant component is described in terms of the inertial loading. The ESWL for the total peak response is then expressed as a linear combination of the background and resonant components. A closed-form formulation of the ESWL based on this framework utilizing an analytical wind loading model is presented. The gust response factors and ESWLs for various alongwind response components at different building elevations are discussed to highlight advantages of the proposed scheme.
