Abstract

A Performance-Based Wind Engineering (PBWE) framework for assessing the serviceability limit state of tall buildings is considered. The immediate focus is on a key component of this procedure which involves creating an appropriate coupling interface between two independent fluid and structural solvers. The fluid solver (ANSYS FLUENT) uses the finite volume method to model the wind field and predict the wind-induced loads. The structural solver (Strand7) applies the finite element method to model the resulting dynamic response. The requirement of the coupling algorithm is to appropriately consider the interaction phenomena involving the wind and the tall building. Clearly, no single coupling algorithm exists which may be appropriate for all fluid-structure interaction problems; the choice depends on an appropriate level of detail and accuracy in a given simulation setting and has a significant impact on the computational demand and accuracy. The decision on the level of complexity for this particular coupling problem is related to the inherently probabilistic context of the PBWE framework and its ability to account for a whole range of uncertainties. The code for the coupling interface has been developed using Microsoft VBA and its functionality will be demonstrated using a case study of a standard 49-storey tall building. Attention will be focused on its capabilities and the potential consequences of its limitations.
