In urban areas, adjacent structures can be seen in any insufficient distance from each other, because of economic reasons ‎and refusal of acquired minimum separation distance according to seismic previsions. Collapse capacity assessment of ‎structures is one of the important objectives of performance-based seismic engineering. The purpose of this study is to ‎consider the pounding phenomenon and P-Delta effect in seismic collapse capacity assessment of structures. For this ‎purpose, 2-, 4-, 6- and 8-story adjacent structures with different conditions of separation distance among them, were ‎modeled in the OpenSees software. Furthermore, Incremental Dynamic Analyses (IDAs) were performed using 78 far-field ‎ground motion records to compute the collapse capacities of adjacent structures. The results obtained from IDAs for ‎adjacent structures show that during pounding, taller structure reaches its collapse capacity earlier than shorter one. In ‎addition, by considering the P-Delta effect and increasing the distance between adjacent structures, time of collapse and ‎number of impacts increases. According to results, considering the P-Delta effect in modeling has significant influence in ‎seismic collapse capacity assessment of pounding structures.‎
