Nonetheless, few studies have focused on the effect of topography amplification on the seismic vulnerability of buildings adjacent to slopes. In this study, using “match up damage index to damage thresholds” method introduced in HAZUS, fragility curves were developed for steel momentresisting frames (SMRF) built adjacent to slopes. A two-dimensional finite-element model of the soil was implemented in ABAQUS to develop the fragility curves. Six models of combination of soil-structure and topography were considered. Furthermore, three types of buildings at different distances from the crest of the slope were considered. The results indicated that slope effect leads to up to 37% increase in the damage probability and illustrated that amplification factor had a range of to , moreover, in comparison with slight states, the probability damage growth rate in moderate and extensive states are higher. 1. Introduction According to HAZUS, the fragility curves of the buildings are obtained using the median values of interstory drift ratio of the building, defined in four damage states of low, medium, extensive and complete. Generally, the damage is estimated based on several parameters such as type of the building, height of the building, and level of seismic .
