This chapter first introduces the formulation of mean wind load and the concept of wind force coefficients. The torsional divergence and critical wind speed of a long‐span bridge are then discussed, based on a two‐dimensional bridge deck section model. Three‐dimensional non‐linear aerostatic instability analysis, considering lateral‐torsional divergence, follows, using the finite element method, and this modeling technique for long‐span bridges is discussed to some extent. The finite element method‐based mean wind response analysis is finally discussed and applied to the Stonecutters cable‐stayed bridge as a case study.
