Combined with the design of three-stage fortification standards of highway bridges and two-stage seismic design, it is widely used in wind-resistant design of highway bridges. The criteria for fortification of highway bridges and bridges under windy conditions are discussed. The principle of multi-level fortification of highway bridges and bridges is proposed. The design idea of two-stage wind-resistant design for highway bridges is expounded. This provides a feasible approach for highway bridges to optimize design.
