This chapter first presents a finite element‐based framework for buffeting analysis of long‐span cable‐supported bridges under skew winds in the frequency‐domain, based on the linear quasi‐steady theory and the oblique strip theory in conjunction with the pseudo‐excitation method. The frequency‐domain framework is then extended to the time domain in terms of the spectral representation method, the convolution integral and the Newmark numerical method. The fundamental aerodynamic information required in the frameworks is obtained in wind tunnels by using specially designed test rigs and typical oblique strip models of a bridge deck. The proposed frameworks are finally applied to the Tsing Ma suspension bridge to compute the buffeting response caused by skew winds during Typhoon Sam, and to compare the computed responses with field measurement results.
