The combination coefficients of seismic and wind loads for multilevel designing buildings and structures in high seismic regions are considered. For design and maximum design earthquakes equiprobable pairs of seismic and wind loads are determined.  Correspondingly, these pairs are iven coupling coefficients for the loads under consideration, which determine the dependence of one combination coefficient on the other. In constructing the equiprobable pairs, the wind load is described by Weibull law and seismic load is described by Poisson’s law. It is shown that for the seventh wind zone with high seismic intensity in calculating structures under the action of the esign earthquake, the combination coefficients are close to 1, and in calculating structures under the action of the maximum design earthquake they are less than 1, and therefore it becomes necessary to choose the most dangerous pair of seismic and wind loads.
