Seismic microzonation maps for Skopje (Macedonia) are presented based on the Uniform-Hazard-Spectrumud(UHS) methodology. UHS satisfies the guidelines for performance-based design (PBD), which require specificationudof two sets of spectral amplitudes, one for which the structure will remain essentially linear, and the otherudfor which it will undergo a nonlinear response. The UHS method also considers the contributions from largeuddistant earthquakes and includes simultaneous effects of site geology and site soils. The maps presented includeudthe effects of near and distant large earthquakes in a balanced way, spatial distribution of seismic activity, siteudgeology, and site soil properties.
