Keywords:Microzonation maps, which include descriptions of site geology and site soil properties Contribution of a large distant earthquake to the design strong motion amplitudes Computation of seismic hazard for earthquake sources, which follow different attenuation laws A B S T R A C T Seismic microzonation maps for Skopje (Macedonia) are presented based on the Uniform-Hazard-Spectrum (UHS) methodology. UHS satisfies the guidelines for performance-based design (PBD), which require specification of two sets of spectral amplitudes, one for which the structure will remain essentially linear, and the other for which it will undergo a nonlinear response. The UHS method also considers the contributions from large distant earthquakes and includes simultaneous effects of site geology and site soils. The maps presented include the effects of near and distant large earthquakes in a balanced way, spatial distribution of seismic activity, site geology, and site soil properties.

Keywords:Microzonation maps, which include descriptions of site geology and site soil properties Contribution of a large distant earthquake to the design strong motion amplitudes Computation of seismic hazard for earthquake sources, which follow different attenuation laws A B S T R A C T Seismic microzonation maps for Štip (Macedonia) and its surroundings are presented based on the uniformhazard-spectrum (UHS) methodology. Such mapping satisfies the guidelines for performance-based design (PBD), which requires specification of two sets of spectral amplitudes-one for which the structure will remain essentially linear, and the other for which it will undergo a nonlinear response. The UHS method also enables us to include contributions from excitation by large distant earthquakes as well as the simultaneous effects of site geology and site soils. Thus, the maps we present include, in a balanced way, the effects of near and distant large earthquakes, spatial distribution of seismic activity, the site geology, and the site soil properties.
